Bump to linux-4.x.y #3

ndoo · 2016-07-12T00:42:25Z

linux-3.4.y is quite an old release, and the amount of changed lines from upstream kernel is not too much.

Are there plans to work on a newer kernel version? Also it would be great if support for this SoC is upstreamed.

friendlyarm · 2016-07-27T03:09:35Z

Thank you for your attention. In general we focus on a kernel which gets support from chip vendors. If chip vendors release a new kernel usually we will catch up with it otherwise we may not do it.

ndoo · 2016-07-27T04:07:13Z

Thanks for the comment. It would bring about a lot of nice things like having updated device tree support.

sarietta · 2016-08-23T06:26:26Z

@friendlyarm is there any word from the chip vendor (Nexell I believe) about when they are going to release a new version?

Supporting 4.x.y on some of your products would be a enormous win.

igorpecovnik · 2016-08-23T08:36:04Z

We just added 4.6.7 and 4.7.2 for H3 based boards, first one is Nanopi Neo: http://www.armbian.com/nanopi-neo/

ndoo · 2016-08-23T08:39:28Z

This issue is specifically referring to linux-3.4.y boards i.e. Nexell boards.

igorpecovnik · 2016-08-23T09:16:36Z

With Nexell I haven't done much of a research yet but moving from "old android kernel" toward recent is a heavy project even for experienced crews, especially if documentation is poor, if we need to face blobs and (c) issues. How far and what was already done, don't know and can't really comment. Out of all dev boards, what is known to me, good mainline support is on: Rpi, most popular Allwinners, some imx6, ... , rk3188, odroid xu4, ... Even Samsung chips have issues on mainline kernel what prevents usage in productive environment, while you can use first three from the list mostly without any serious problems.

ndoo · 2016-08-23T09:24:36Z

Yup, the request is intended to be addressed to FriendlyArm and Nexell to complete the port as vendors of the boards rather than a request for the larger community to unbreak the codebase and forward port :)

sarietta · 2016-08-23T18:15:24Z

Exactly @ndoo. I have attempted to email the contact noted in arch/arm/boot/cpu.c at Nexell about any possible updates, but I'm not sure if that will work.

It seems to me that someone at @friendlyarm must have a contact at Nexell who can at least provide a timeline.

awl1 · 2016-08-24T18:47:33Z

Have a look here for the latest news:
http://www.friendlyarm.com/Forum/viewtopic.php?f=44&t=204&start=10

Nexell:

There will be a 64-bit based linux kernel on S5P6818 and the kernel version will be 3.18 or up. But when will it be released, we don't know exactly. It's under developing. The schedule is at the end of 2016 the 64-bit kernel will be released.

FriendlyARM:

Once we get this support we will arrange its development but we cannot say it for sure exactly we will be able to release it since it depends on various factors

daiaji · 2017-04-08T14:50:52Z

Oh, it's 2017
No new kernel messages

spacecdr · 2017-04-08T14:56:21Z

They have totally gave up this project... never an update... 🙁

@spacecdr
A good news！
I found SamsungARTIK
Artik 710 (S5P6818) has available 4.4 ARM64 kernel
Metro94 seems to be working on some NanoPi-M3 bootloader and kernel porting
😄

ghost · 2017-05-21T19:50:49Z

Dear Metro94, dear jensen, dear hmz007 Dear Friendly-arm community,

I would like to use the kernel from the A710/v4.4 branch of https://github.com/SamsungARTIK/linux-artik on the Nanopi-M3. With gcc-linaro-6.3.1-2017.02-x86_64_aarch64-linux-gnu.tar.xz toolchain from Linaro, I get :

./arch/arm64/boot/dts/nexell/s5p6818-artik710-raptor-rev01.dtb
./arch/arm64/boot/dts/nexell/s5p6818-artik710-explorer.dtb
./arch/arm64/boot/dts/nexell/s5p6818-drone.dtb
./arch/arm64/boot/dts/nexell/s5p6818-artik710-raptor-rev03.dtb
./arch/arm64/boot/dts/nexell/s5p6818-artik710-raptor-rev00.dtb

and 211 modules. (I will see later for the three modules bcmdhd.ko nx_vpu.ko vr.ko, for now, I just need a reasonable recent kernel able to start an android init service or even just a linux elf binary or bash script)

and a image

arch/arm64/boot/Image

Is it possible to load it ?

-with the nanopi2-lollipop-mr1 branch of https://github.com/friendlyarm/uboot_nanopi2.git ?

if not

-with the A710/v2016.01 branch of https://github.com/SamsungARTIK/u-boot-artik.git or the NanoPi_M3 branch of https://github.com/metro94/NanoPi_M3-U-boot.git ?

if not

-with a mixture of NanoPi_M3 branch of https://github.com/metro94/NanoPi_M3-2ndboot.git + one of the previous mentionned uboot

if not

something even more strange ;) ???

What is the current status of Samsung/Nexell/friendlyarm collaboration on these reasonable recents uboot + 64bits-linux/drivers ???

I mean... come on... guys, it's May 2017, Jonathan Corbet announced yesterday on lwn.net

The 4.11.2, 4.10.17, 4.9.29, 4.4.69, and 3.18.54 stable kernel updates have all been released with the usual set of important fixes. Note that this is the final update for the 4.10 kernel.

and Greg KH announced in September 2016 on lwn.net

the 3.14.y LTS kernel series is now end-of-life ...

Please Friendly-Arm, update the wiki and give us a way to have reasonable recent uboot/linux/{ubuntu/android} software !! and not a 32bits 3.4.* kernel thas has already reached it's Projected EOL (https://www.kernel.org/category/releases.html)

We can help, test, debug, but the bare-metal stuff have to be done by friendly-arm / nexell / samsung ...

Thank you all in advance !

friendlyarm · 2017-05-23T03:04:55Z

Actually we tried code from https://github.com/SamsungARTIK/boot-firmwares-artik710 and https://github.com/SamsungARTIK/u-boot-artik and made an SD card. Unfortunately that SD card couldn't boot our board. We may have to wait for Nexell to release its latest BSP. We can do development based on u-boot-artik and https://github.com/SamsungARTIK/linux-artik but without a workable boot-firmware we cannot boot our board and test an image.

ghost · 2017-05-23T03:09:04Z

Have you tried this alternative to 2ndboot.bin ?

https://github.com/metro94/s5p6818_bootloader

it boots ...

I have compiled the bl1 firmware from sources bl-artik710 with BOARD set to DRONE and it works. I have used NSIH based on drone-sd-64.txt file stored in reference-nsih in this project. Below is the script used by me to embed the compiled bl1 and u-boot in SD card. Note that first partition on the SD card should start at 2048 sector. The script should be updated before use, the environment variables with SD device and location of the bl1 and u-boot sources shall be set appropriately.

The Linux kernel is much more problematic, but I have managed to boot the linux-artik, branch A710v4.4. To be precise, I have entered shell within initial ramdisk, through serial port:

/ # uname -a
Linux S5P6818 4.4.19+ #184 SMP PREEMPT Wed Jun 14 21:10:51 CEST 2017 aarch64 GNU

I have used defconfig for drone, too. To be honest, I don't remember all the changes that I have made in the configuration. As I remember, I have disabled some drivers because they have compilation errors. At least DS1307 driver I have disabled.

There were also some important changes in Linux source code. First change I have made in file head.S (arch/arm64/kernel/head.S). The two lines below should be added somewhere at startup, e.g. in el2_setup:

mov	x0, #3 << 20
msr	cpacr_el1, x0	/* Enable FP/SIMD at EL1 */

Second change: in file s5p6818.dtsi (arch/arm64/boot/dts/nexell/s5p6818.dtsi) the "psci" device description I have removed (commented out). Otherwise system panics at smc instruction call. I have also removed all "enable-method=psci" from all processor descriptions.

Third change: a bug in axp228-mfd.c file (drivers/mfd/axp228-mfd.c). Below is the patch. The bug causes memory corruption and kernel panic little later. From unknown reason the driver does not find axp228 chip and returns with error. Before return it releases memory, but bad function is used for that.

 }

I got stuck in CPU configuration - the kernel sees only one processor. In dts file the processor "enable-method" is set to "psci", but I don't know how this might work. The smc instruction is disabled at exception level 3 and not intercepted by exception level 2. Even if it would be enabled, the boot loader lacks of handling code.

The bootloader provided by metro94 has one bug in trustzone configuration, but after fix the bootloader works also. It may be used instead of bl1-artik loader. Below is the needed patch:

avafinger · 2017-06-16T15:57:11Z

Nice work!
If you could create/fork all the code (patched code) and the instructions to build it in github would be awesome and kernel developers could try to help trimming this.
Anyway i will follow your progress with interest.

rafaello7 · 2017-07-05T19:51:40Z

Actually I'm trying to work with vanilla kernel 4.11.6. I have some trouble when all 8 cpu's are enabled. System behaves unstable, but with 4 processors seems to work pretty. At least ethernet, display, usb and serial port are working. I'm writing this post from NanoPi with the 64-bit kernel. Device drivers I have moved from Samsung Artik kernel 4.4. Here is my desktop:

Graphics driver is nice, because screen resolution may be changed on the fly. No need to compile kernel to change resolution.

I can upload prebuilt boot loader and kernel image. But work is in progress.

Nice work rafaello7 !!!
The best would be to fork on github : bl-artik710 , u-boot, linux-artik so you can push your progress.
In that case, we could follow/test/push-request then.

rafaello7 · 2017-07-05T21:26:59Z

All my work is on github:
bl1-nanopi-m3
u-boot-nanopi-m3
linux-nanopi-m3

Additionally I'm using nanopi-load tool to upload images to device through USB port instead of embedding in SD card. But booting from SD card is also possible.

I provide some instructions soon, how to build and run all together. Maybe in README on bl1-nanopi-m3 project.

daiaji · 2017-07-06T04:43:07Z

@rafaello7 coooooool！
Can code work on NanoPC-T3?

rafaello7 · 2017-07-06T05:55:02Z

Yes.

rafaello7 · 2017-07-06T19:37:43Z

I have added build instructions on bl1-nanopi-m3 page.

metro94 · 2017-07-08T03:55:50Z

Sorry for ignoring the issue of @rafaello7 for a long time. He has made a great progress on it. Actually my NanoPi has been sold, so I'm afraid not to maintain s5p6818_bootloader and s5pxx18_load from now on.

rafaello7 · 2017-07-10T12:44:07Z

@metro94 no problem ;)

As of Linux 4.11.6, there are stability problems with this kernel when all 8 CPU's are brought up. Kernel boots correctly, but just after boot I'm performing simple test: I'm starting a few "yes" processes:

yes >/dev/null &
yes >/dev/null &
....

Kernel hangs just after 6th process start. I have no idea how to fix the problem. Kernel 4.4 from Samsung Artik does not have the problem, but I have no idea how to find the change that makes difference.

I will try to prepare the Artik v4.4 kernel for NanoPi. Kernel 4.11 goes aside for now.

rafaello7 · 2017-07-11T20:50:04Z

I have found the problem reason. In fact, these were two reasons: two long extension cables between USB socket on my PC and micro USB cable connected to NanoPi. I think you can guess the rest. After shortening the distance NanoPi seems to work stable with 8 CPU's.

JamesKingdon · 2017-07-11T20:59:40Z

Excellent - that's exciting news!

PVlado · 2018-05-13T13:01:41Z

So, now I change location to SD card. Installed fixed Release 1.2.
And
root@T3plusMMC:/home/vlado/Downloads/Rafal/u-boot-nanopi-m3-master# nano-blembed u-boot.bin
unable to determine boot device

this
dd if=/dev/mmcblk0 bs=4 skip=166 count=1 | od -t x4
give 03100302
dd if=/dev/mmcblk2 bs=4 skip=166 count=1 | od -t x4
give 03100301

PVlado · 2018-05-13T13:03:08Z

I tried it /dev/mmcblk2p1 instead of uuid for /boot
Did not help

PVlado · 2018-05-13T13:05:08Z

can you give me contact?

rafaello7 · 2018-05-13T14:06:28Z

Please install release 1.3. I have added possibility to specify boot device in command line:

nano-blembed u-boot.bin /dev/mmcblk2

Are you booting from SD card or from EMMC? You should install updated bl1 on SD if you are booting from it.

PVlado · 2018-05-16T15:18:55Z

@rafaello7
Can you give me link to datasheets where it described?

I allege change in startup_aarch64.S line 61 may help. This line and subsequent one are the SDRAM memory parameters. Maybe change of 0x03100301 to 0x03100302 would help?

rafaello7 · 2018-05-16T20:38:06Z

@PVlado I don't know about any such datasheets. I looked at bl1 source code.

@PVlado it looks bad. I mean the oops. Does it appear with 2GB ram only?

You can also try to load the 4.14 kernel using loaders from FriendlyARM.

PVlado · 2018-05-21T13:09:05Z

All img. from FA works OK.
32 and 64 bit

PVlado · 2018-05-21T13:15:16Z

On my board it happened only with it:
startup_aarch64.S line 61 change of 0x03100301 to 0x03100302
and
include/configs/s5p6818_nanopim3.h
CONFIG_SYS_SDRAM_SIZE 0x80000000

awl1 · 2018-09-06T23:01:21Z

Hello,
can someone please provide an update about the status of booting the 2GB NanoPC-T3+ variant from emmc using Ubuntu Bionic (18.04) and the Armbian (or Rafaello7) 4.14 kernel?
Is this currently possible? If not, what exactly is missing in Armbian to allow for booting from emmc?
Many thanks!

igorpecovnik · 2018-09-07T04:53:50Z

It is possible since yesterday. armbian/build@86a00ad Images are not yet updated and you need to build on your own (with parameter EXPERT="yes") or wait a few days.

awl1 · 2018-09-07T20:36:52Z

That's great news, Igor! Thanks a million for your great work on Armbian and the M3/T3/T3+! 🥇

igorpecovnik · 2018-09-08T05:54:09Z

You are welcome :) https://twitter.com/armbian/status/1038146549124083715

awl1 · 2018-09-08T07:24:55Z

@igorpecovnik Just one more question, if I may:

Regarding the old, 1GB, NanoPC-T3 (without "+", but which also already had an 8 GB emmc), when I build Armbian myself using board "nanopim3", does it now also offer the chance to install onto emmc for this old board?
In case it does not (yet), as the old T3 is very similar to the T3+, would it be feasible to add this even though it is marked as EOS, as I hope this would be a very minor change due to the similarity of the boards?

Thanks a million one more time! 😄

igorpecovnik · 2018-09-08T07:47:43Z

It is possible that 1G version won't boot at all. You might need different boot loader settings (the same as for M3/Fire3). Let's do it this way - I will prepare a CSC build target for the one without + and if it works for you it can have the same status. Boards are nearly identical.

awl1 · 2018-09-08T07:51:29Z

Great! 👍 Once you've prepared this (did I get you right that it will be a new board name, such as "nanopct3" without plus), just give me a ping!

And: Clearly, there's no need to hurry - enjoy your weekend!!! 😄

igorpecovnik · 2018-09-08T08:03:57Z

Briefly checked: 2G hacks are tied directly to the + board, eMMC size does not matter and its made universal, ... and that's all that is different. BT does not work yet on + and it will not work here ... I have to dive into that once in the future.

Thanks. Enjoy yours as well!

awl1 · 2018-09-08T08:47:01Z

Thanks again, @igorpecovnik

Regarding Bluetooth, I might be able to help, because I got it working back in the very old days when I had just received my first T3 - see this post on the FA forums:
https://friendlyarm.com/Forum/viewtopic.php?f=44&t=312#p958
and the file attachment below from back then.

Once I found some time to install onto my T3+, I will report back here whether I think that my old BT work will be of any help...

nanopi_bluetooth_fix.tar.gz

awl1 · 2018-09-08T17:32:16Z

Bad news: Armbian_5.59_Nanopct3plus_Ubuntu_bionic_next_4.14.68_desktop.7z does NOT work at all for emmc on my T3+ 😞

After copying rootfs onto emmc with nand-sata-install (where I only see option 1 - boot from emmc, system on emmc), when I reboot with SD card removed, it simply hangs at Nano-Pi logo with Armbian u-boot.

When I leave the SD card in the SD card slot, it looks like it might boot from emmc u-boot, but it then always mounts SD card from /dev/mmcblk2p1 as the root partition and leaves /dev/mmc0blk alone. 😢

Will continue testing tomorrow and report back about u-boot logs, but I need to reestablish my NanoPC serial console debugging environment...

awl1 · 2018-09-08T17:36:21Z

BTW: I also seem to have issues with wired eth0 on T3+ kernel 4.14.68 when connected to at least one of my switches - will also report back about this later, sometimes no connection, sometimes a bad connection with very erratic latencies (up to 1300ms) and dropped packets... 😞

igorpecovnik · 2018-09-08T17:37:36Z

I guess I must have made some mistake somewhere, serial console is a must ... Have you tried to power cycle? Regarding network ... never experience any troubles. That is odd.

awl1 · 2018-09-09T10:09:00Z

@igorpecovnik
OK, so having exectuted nand-sata-install, selected option "1" (boot from emmc, system on emmc), here is the serial console NanoPi U-Boot log output when trying to boot from emmc without SD card inserted: putty.log

I am wondering why there is a "CRC" error in the U-Boot environment - maybe nand-sata-install fails to correctly write an U-Boot environment?

Will try to compare the output to that of a successful FA "FriendlyCore" boot from emmc with kernel 4.4.x and Ubuntu xenial and report back one more time...

awl1 · 2018-09-09T10:21:12Z

Second update: eth0 wired networking issue seems to be an incompatibility between kernel 4.14 eth0 driver and only one out of three switches that I own. Networking works fine using the other two as well as when connecting directly to the DSL router, so it looks like this is an issue with this particular old GbE switch...

daiaji · 2018-09-09T12:15:25Z

@awl1 @igorpecovnik Though hardly anyone reported
But I did encounter T3 network related problems.
It seems that T3's NIC does not work under gigabit network.
Now I connect T3 to another 10/100 BaseT router and he can work normally.

In fact, I think the router of MT7621 should not be old.
Maybe you can try the old kernel provided by friendlyarm.

igorpecovnik · 2018-09-09T14:17:54Z

I am wondering why there is a "CRC" error in the U-Boot environment

That is not a problem but the problem is wrong default boot environment. I didn't clean it (env default -a) before testing and if I clean it now I get the same error as you get. Will be fixed asap.

A network is another story. It works well on both of my switches, gigabit or fast ethernet.

igorpecovnik · 2018-09-09T15:20:33Z

Fixed. Flash this u-boot to eMMC and it should work. Perhaps you will need to clear environment with env default -a

dd if=bootemmc.img of=/dev/mmcblk0 seek=1 status=noxfer

bootemmc.img.gz

awl1 · 2018-09-09T15:50:31Z

@igorpecovnik Bingo! Many thanks, Igor! I can confirm that it does work fine now! 🏅 👍

Will try to look into the Bluetooth issue later tonight, could be possible I might be able to pay something back (see above with regards to brcm_patchram_plus)... 😃

Regarding eth0, I tend to think the kernel is most probably fine, as it works ok with all but one of my switches/routers. When I find some time, I might check whether the dev kernel changes something to the better for the affected switch, but that's really low prio...

awl1 · 2018-09-09T16:34:48Z

Regarding Bluetooth: Hmm - it looks like kernel 4.14.x may still be missing kernel modules for Bluetooth - we need /sys/devices/platform/bt_bcm.0 to be able to access AP6212 Bluetooth device!?
Will check this in Armbian vs FriendlyARM kernel source and report back...
