esp32c6 support (IDF v5.2) #11869

andrewleech · 2023-06-26T01:55:07Z

The is esp32c6 officially supported in IDF v5.1 but requires a number of changes to work...
Pulling together changes and generic board support needed here.

I'm expecting these lines to not be required for real / merged support, but I've been having issues with the risk-v compiles and this is part of the WIP to get it going.

andrewleech · 2023-07-26T11:59:58Z

I've hacked past a bunch of compile flags to get further in the compile, but still not complete.

Bluetooth is not working - #include "esp_nimble_hci.h" is not available unless cmake set(CONFIG_BT_NIMBLE_LEGACY_VHCI_ENABLE "y") is set, but once that's enabled a bunch of other compile errors jump up.

ADC does not support the legacy api currently being used in idf v5 support.

I should rebase this on top of #12952 to include everything already fixed there.

add this to the sdkconfig file:

Maybe its the order in which sdkconfig files are resolved in mpconfigboard.cmake?
Here is mine:
set(IDF_TARGET esp32c6)

set(SDKCONFIG_DEFAULTS
boards/sdkconfig.base
boards/sdkconfig.ble
boards/ESP32_GENERIC_C6/sdkconfig.c6usb
)

I dont know if it matters. I seem to remember running into this problem and renaming sdkconfig to sdkconfig.c6usb resolve it. Though totally possible I incidentally resolved it in some other way, and the file name was irrelevant.

mattytrentini · 2023-11-26T01:16:35Z

Seems similar here:

set(IDF_TARGET esp32c6)

set(SDKCONFIG_DEFAULTS
    boards/sdkconfig.base
    boards/GENERIC_C6/sdkconfig.board
)

Confusing!

For anyone that is interested, i have a hacked up fork that appears to be working on C6. I havent done any robust testing yet. Use at your own risk. However, it may provide additional insight for the professional devs on here.

Can you guide me on how can I test your fork? I'm unable to find the proper firmware to esp32-c6 on https://micropython.org/download/?vendor=Espressif.

I haven't seen it in your repository either. Where to get it?

With my older boards, I was downloading FV from this page and then installing it with 'Thonny' IDE. Is there another way that I should attempt for this board?

That downloads list are the officially supported builds generated by cicd. To get this to work on C6 you have to build and compile the binaries yourself. You may want to first start with building the main branch by following these instructions. If you get that working, then take a whack at building my forked repo.

Ok, that sounds doable. But, I need to clarify some things:

I understand that you propose to first try to do a normal .bin file using the main/official micropython repo. The thing I don't understand is, what and how should be set for the sake of using this main repo in a way that it will work with a particular model of ESP32. The binary should be set up in a way that it will be compatible with a particular board. In other words, I know that for that practice I need to use another board because the official repo doesn't support ESP32-C6 and I have ESP32 WROOM 32D too, so it's not a problem, but what I don't know is what to do, to prepare files for compilation in a way that they will be compatible with, for example, ESP32 WROOM 32D. Where to find the most up-to-date documentation for this?
Besides creating this binary, do I need to establish any Espressif IoT Development Framework firmware on ESP32, before I flash it with this binary we were speaking about before?
Doing such actions as preparing my own binary, do I risk bricking the board in the process of flashing?
Can you elaborate on the limitations of your version (fork) of micropython regarding ESP32-C6? Are you aware of what doesn't work, or - at least - what is working at this moment?

Take a look at this file. I set the build target and a couple CMake variables such that the build points to the correct sdkconfig files under ports/esp32/boards.
https://github.com/jschott780/micropython/blob/master/flash-build.sh

Yeah, you have to clone this repo, and follow the build instructions in the README.
https://github.com/espressif/esp-idf
Once you've built the esp-idf tools, you can do then execute "export.sh" which will place the build tool chain on your path (idf.py).

Yep, you can brick your board.

No idea of the limitations yet. I'm about to test my application in the next few weeks. Entirely possible nothing works.
For clarification, I'm not presenting this fork as a shrink wrapped bug free solution. I was able to get the build to a point where the micropython shell is accessible. Just providing this as a reference to help move the ball forward.

IhorNehrutsa · 2023-12-27T07:29:01Z

Please rebase current branch to top of master

andrewleech · 2024-01-17T23:58:21Z

I've finally rebased this up to current master, including a bunch of fixes recently contributed by @IhorNehrutsa
It was a rather complicated rebase as lots has changed in esp32 in master recently, I haven't tested this branch yet to see how close it is to working.

andrewleech · 2024-01-18T03:54:49Z

To build and flash:

cd micropython
docker run -it --rm -e BOARD=ESP32_GENERIC_C6 -e UID=$(id -u) -v $(pwd):/micropython -v /sys/bus:/sys/bus -v /dev:/dev --net=host -w /micropython espressif/idf:v5.1.2 bash -c '\
useradd -ms /bin/bash -g root -G sudo -u $UID esp;\
git config --global --add safe.directory /opt/esp/idf;\
su esp -m -c ". /opt/esp/entrypoint.sh; export HOME=/tmp; \
make -C mpy-cross && \
make -C ports/esp32 BOARD=$BOARD submodules && \
make -C ports/esp32 BOARD=$BOARD deploy PORT=/dev/ttyACM0; \
"'

This command looks nuts at first glance to be sure... it's starting a temporary docker container from the official esp idf image and running the build commands inside it. There's some mucking around with users (inside the container) so that the build can access the idf files correctly while not breaking the permissions on the micropython code shared into the container.

Using docker means though you don't need to install and configure anything esp / idf / compiler related on your PC, just docker. It also makes it easy to switch between different versions of IDF, just pick the appropriate image version!

@mattytrentini espressif/esp-idf#11924 - currently still broken in the v5.1 image, v5.1.2 was released ~ 1 week before that fix was merged.

There's also compile failures relating to ADC... probably closely related to what @IhorNehrutsa fixed previously which I've likely re-broken in the rebase to master where a lot of changes have been made to consolidate machine/adc functionality across ports.

kdschlosser · 2024-01-27T02:49:47Z

I am not sure why you are having such a hard hour getting it to compile properly using IDF5.1.2

I know I am not compiling for the C6 is the ESP-IDF API different for the C6 vs the S3?

mattytrentini · 2024-01-27T08:33:22Z

I know I am not compiling for the C6 is the ESP-IDF API different for the C6 vs the S3?

Yes. Some APIs are deprecated but still supported (as legacy) on the S3 and other micros. Those legacy APIs don't exist for the C6. So some components need to be rewritten.

kdschlosser · 2024-01-27T17:19:31Z

ahhh OK. That makes sense then.

mancausoft · 2024-03-12T09:27:04Z

I was able to compile micropython using the code from: #11869 (andrewleech:esp32c6)
I rebase it to: #13775 (DvdGiessen:esp32_idf52)

and fix ADC calibration and a problem with UART name.

Do you have a list of what is working currently and what's not for this board?

Is there currently a stable version anyehere - if so, where do I find it?

mattytrentini · 2024-05-01T01:22:32Z

I've just added a board definition for the M5Stack NanoC6 (limits the pins to and defines I2C(0) to use the 'grove' port).

>>> from machine import Pin, I2C
>>> help(Pin.board)
object <class 'board'> is of type type
  G1 -- Pin(1)
  G2 -- Pin(2)
  IR_LED -- Pin(3)
  LED_BLUE -- Pin(7)
  BUTTON -- Pin(9)
  NEOPIXEL_POWER -- Pin(19)
  NEOPIXEL -- Pin(20)
>>> I2C(0)
I2C(0, scl=1, sda=2, freq=400000)
>>>

Do you have a list of what is working currently and what's not for this board?

I've tested Pin, I2C, NeoPixel, and - lightly - network.WLAN. bluetooth appears to work but there may be some failing tests, it hasn't been thoroughly tested. Are there particular features you're interested in that I could possibly test?

Is there currently a stable version anywhere - if so, where do I find it?

It hasn't been merged yet, so builds aren't part of the regular CI system. For now, you ought to build it yourself, though I've attached the my latest build of the ESP32_GENERIC_C6 that you can use. To deploy:

> esptool.py --chip esp32c6 erase_flash # Only necessary when the partition layout changes, ie the first time you deploy
> esptool.py --chip esp32c6 --baud 460800 write_flash -z 0x0 esp32_generic_c6_firmware.bin

(You may need to use --port if you have multiple devices connected.)

I've found an issue with the ADC implementation:

I've found an issue with the ADC implementation:
[snip]

Hmm, it may need a little more work - that C6 ADC peripheral looks different again to the rest of the ESP32 family. Specifically, it has only one 12-bit SAR which can be assigned to seven pins. I think the single ADC channel is unique to the C6?

But thanks for the bug report and patch - that helps, a lot!

p2k · 2024-05-03T06:37:42Z

For reference, this seems to be the relevant documentation. Indeed, it shows a 12-bit SAR with 7 channels/pins GPIO0 through GPIO6. The fact that 13 bit are enabled in my patch relate to the "Deprecated ADC APIs" being used here, which for some reason don't allow the other bit settings. The API documentation is unclear about all of this, even hinting at 9 through 13 bits being allowed and that there's 2 ADC units and up to 10 channels.

Not sure what to make of all of this, but I guess we'd have to fix machine_adc.c and machine_adc_block.c to reflect this, as you already pointed out.

I'm interested in this development since I have also obtained an ESP32-C6 dev board, but none of the builds work.
Over the last few days I've tried with the build linked here as well as building the thing myself, for all possible ESP-C6 board types currently in this branch.

While all of them flash fine, the only output I get over the serial interface is this:

ESP-ROM:esp32c6-20220919
Build:Sep 19 2022
rst:0x1 (POWERON),boot:0xc (SPI_FAST_FLASH_BOOT)
SPIWP:0xee
mode:DIO, clock div:2
load:0x40875720,len:0xed4
load:0x4086c410,len:0xaf0
load:0x4086e610,len:0x2b3c
entry 0x4086c410

Flashing other firmwares (e.g. the blink examples) works fine.

Does anyone have any idea what I am doing wrong here and/or how to troubleshoot this further?

Yes, certainly! Your problem looks like the one I had some days ago, to which I've found the solution. In short: Just use the other USB port on the Dev Kit, the C6 firmware by default does not use the serial aka UART port for its console.

EDIT: I've checked the link you sent and your board definitely has two USB ports, albeit they are labelled differently.

andrewleech · 2024-05-17T07:53:09Z

Ah that's interesting, I've got two C6 modules but both are small and only have the USB that's natively handled by the chip itself, they don't have a UART connected. I for one am very happy esp chips are moving towards built in USB rather than needing separate conversion chips.

I didn't realise other Dev boards for this chip might still default to a UART converter!

p2k · 2024-05-17T08:01:56Z

When I first got the C6 Dev Kit and found that it has two USB ports, I honestly was a bit confused. But at the end of the day, this frees us to use the UART port for other applications; there's quite a few peripherals which work with a serial connection. The fact that the Dev Kit still has a conversion chip and thus a second USB port is probably meant for easier debugging purposes and, well, why not.

Meaning to say that I'm fine with the default setting of using the main/integrated USB for the Micropython console, but I still suggest that this should be documented somewhere.

DaanOlbrechts · 2024-05-17T08:07:43Z

Yes, certainly! Your problem looks like the one I had some days ago, to which I've found the solution. In short: Just use the other USB port on the Dev Kit, the C6 firmware by default does not use the serial aka UART port for its console.

Thanks for the assistance, this is exactly what is going on! The REPL is available on the second USB port.

andrewleech · 2024-05-17T08:11:19Z

For reference, this seems to be the relevant documentation.

The correct doc links are helpful too, certainly the best path would be to follow those docs and use the newer drivers, moving away from the 4.x deprecated drivers is a slow but desirable goal certainly!

andrewleech · 2024-05-17T08:38:10Z

Certainly, it is the ESP32-C6-WROOM-1-N8 variant listed here.

It would probably be worth making a board definition fit this that enables the UART repl as well to avoid the confusion!
