Problem with 8u2 (uno)

[thesymbol]

I have been trying to upload the HoodLoader2_NoUSB_Blink to the 8u2 (since i do not have the space to fit the HID library for keyboard). but every time it fails to verify. here is the output from Arduino 1.6.1

Sketch uses 646 bytes (15%) of program storage space. Maximum is 4 096 bytes.
Global variables use 9 bytes (1%) of dynamic memory, leaving 503 bytes for local variables. Maximum is 512 bytes.

do you use the newest 2.0.4? Have you installed the 8u2 version? the
16u2 version will not work on an 8u2.
I never tested it since i dont have a 8u2.

Does the usb serial still work to flash the 328?

Yes im using the 2.0.4 version for the 8u2, the flashing went through without any errors, (i used a Arduino Mega ADK to flash the UNO with Hoodloader 2.0.4)

And yes i can still upload sketches to the 328. (for example the blink from arduinos example sketches).

i used these settings in the ino sketch:

// make some of these false to reduce compile size (the ones you don't want)
#define USE_ATMEGA8U2 true
#define USE_ATMEGA16U2 false
#define USE_ATMEGA32U2 false
#define USE_AT90USB162 false // todo, not supported

// also use Mega 16u2 bootloader files?
#define USE_MEGA_BOOTLOADER false

// force Mega bootloader for blind pin selection/DFU hex file
#define FORCE_MEGA_BOOTLOADER false

// DFU options (16u2 only)
#ifdef USE_ATMEGA16U2
#define USE_ATMEGA16U2_DFU true
// use the full 16kb DFU Bootloader with USB-Serial
// you have to deactuivate the mega bootloader then
// but you can stull burn a mega DFU file in the followed setting
#define USE_ATMEGA16U2_DFU_FULL false
#endif

[NicoHood]

Interesting. Try the UNO or Mega file. Both should work the same, no
matter what board is used.
Can you try to upload a hex file via avrdude in the tools folder? the
usbserial firmware for example.

I'd have to get a board myself to test this. and I wont buy this myself.

Do you have a 16u2 to test this? Maybe the fuses are set wrong :S
I'd have to retest this myself. Maybe i uploaded crap?

Interesting. Try the UNO or Mega file. Both should work the same, no
matter what board is used.

what files are you reffering to?

Can you try to upload a hex file via avrdude in the tools folder? the
usbserial firmware for example.

Getting the same error, or atleast a similar validation error.

Do you have a 16u2 to test this? Maybe the fuses are set wrong :S
I'd have to retest this myself. Maybe i uploaded crap?

No i do not have a 16u2 to test, i wish i had. :(

[NicoHood]

Too bad the ADK has no 16u2.
In the uploading process you can say 'M' for mega and 'U' for uno. try both.

Otherwise I have no clue why that error occurs. Is it a real atmega 8u2
or atusb9082? What does the print on the chip say?

Where do you live? I'd be willing to test this if you send me the board
on your cost or buy me one. ADK is 25€ on banggood.
Otherwise I suggest you to use a mega and buy a shield separate for usb
host if needed.

it says
ATMEL
mega8u2
and two more rows that i cant read.

i think the uno is a rev 1 since the mega8u2 chip is turned a bit so it looks like a diamond when the arduino is correctly orianted.

I think the mega has a 16u2 but cant make out the text that well, but i wont flash that board since im borrowing it from a friend.

Im not willing to pay for a board tho, i might just try and get my hands on a 32u2 or 16u2 uno later down the road.

[NicoHood]

yeah. just grab a new one.
It would be interesting to get it working though. very weird. And i
have no real idea why. maybe I compiled the files wrong?

Can you please open an issue on github? maybe others have this problem
as well. also as reminder for me.
I will try to recompile the bootloader. Just remind me. I think I
probably forgot to change the size of the bootloader.

this conversation is already on github ;)

Tried to flash an old hid .hex firmware from another project that i used to be able to flash and got this

avrdude.exe: verifying ...
avrdude.exe: verification error, first mismatch at byte 0x0000
             0xff != 0x9a
avrdude.exe: verification error; content mismatch

avrdude.exe: safemode: Fuses OK (E:FC, H:D8, L:EF)

avrdude.exe done.  Thank you.

here is the output from flashing the normal Arduino-usbserial-uno.hex

avrdude.exe: verifying ...

If i take your HoodLoader2_0_4_Uno_8u2.hex file and flash it it goes through and verify correctly

[NicoHood]

how do you flash? via real ISP or via installation sketch?

Totally missed, that this was a github post. though it was by mail from my blog. well.... :D

[thesymbol]

I dont have a real ISP, and im flashing with avrdude.exe from the tools folder directly to the UNO.
i also tried doing the bootloader_converter.lua way but the .hex file's turned into 16384 when the 8u2 only has 8192 of memory to flash to and that will just end badly if i try to flash that.

hehe, the more you know eh? ;)

[thesymbol]

i tried the M way aswell nothing changed.

[thesymbol]

Got some good news, i managed to manually upload the sketch (HoodLoader2_NoUSB_Blink) to the 8u2, but to do so i had to use avrdude and specify at90usb82 instead of atmega8u2 for the -p parameter. im guessing this is because its a rev 1 uno.

The command i used was this:
avrdude -C avrdude.conf -F -p at90usb82 -c avr109 -b 57600 -P COM14 -U flash:w:HoodLoader2_NoUSB_Blink.cpp.hex:i

now the RX and TX leds are blinking as they should :D

[NicoHood]

Try to change this line to at90usb82, restart the IDE and try to upload.
It should then work. If yes, I'll probably add this MCU type as well.

Still weird though.

https://github.com/NicoHood/HoodLoader2/blob/master/avr/boards.txt#L164

[thesymbol]

Already one step ahead of you, did that already (but copied the whole 8u2 section and renamed it to at90usb82).
But i get an signature verification error if i dont specify -F to skip the check.

avrdude: Device signature = 0x1e9389
avrdude: Expected signature for AT90USB82 is 1E 93 82
         Double check chip, or use -F to override this check.

[NicoHood]

that is weird.

So you get an error with the IDE on both 8u2 and at90usb82.
With avrdude you only get an error with 8u2, right?

I am wondering why avrdude accepts the wrong device signature with manual control
A good idea is to provide a blink.hey file. good idea!

The only thing I can think of is to burn the hex file via ISP and not with the installation sketch. maybe the conversion was wrong.
I know this page has to be improved, but you may want to try ISP with one of your other arduinos.

[thesymbol]

So you get an error with the IDE on both 8u2 and at90usb82.
With avrdude you only get an error with 8u2, right?

in the IDE i get the signature verification check error (and it suggest to force it with -F)
so when i enter the same command manually into cmd with the -F parameter the upload goes through successfully.

I am wondering why avrdude accepts the wrong device signature with
manual control A good idea is to provide a blink.hey file. good idea!

The -F parameter makes avrdude skip the verification completely and just uploads the data to the 8u2 without questioning the signature of the device.

https://github.com/NicoHood/HID/wiki/Arduino-as-ISP

Doesnt there exist a list of devices (atmega16u2 etc) with their device signatures? could help in finding why the at90usb82 doesnt match the uno 8u2 chip.

[NicoHood]

here is the signature
https://github.com/nickgammon/arduino_sketches/blob/master/Atmega_Board_Programmer/Atmega_Board_Programmer.ino#L282-L286

try to burn via isp, maybe the installation sketch did something wrong.

[thesymbol]

still no success, still getting the verification error of the device if i use at90usb82 and with atmega8u2 i get the 0xff != 0x0c

[NicoHood]

With an ISP you can do 2 things:
Burn a bootloader and try to upload via bootloader
or flash a program directly

Can you please try both versions? At least uploading the blink via the IDE via programmer should work, since it has nothing to do with the bootloader itself.

[thesymbol]

Uploading normal ino for the 328 works.
I do not have the ADK anymore (had to give it back today) so i cannot test this if i need the ADK as ISP.

but if i do not can you point me in the right direction (im a bit confused by you phrasing) what do you mean by flashing a program directly?

[NicoHood]

You can flash a program via bootloader or via ISP. You can burn Bootloaders only via ISP.

I want to know if its an IDE or chip problem or a bootloader problem. When you upload the blink via ISP there is no bootloader used. If this works, we know that its not a chip/IDE problem.

Then you can burn the bootloader via ISP instead of the installation sketch (which emulates an ISP but a bit different stil, with file conversion etc). Then we know if its an installation sketch problem or a real bootloader problem.

Just buy a new Arduino with a 16u2. One from china is 6,5€ so why not buy one with even a better usb chip? It takes some time till it arrives but otherwise you wont be able to use it, it seems. And I have no idea where to get a 8u2 from and also it doesnt really make sense to buy that "old" chip.

[thesymbol]

Im going to buy one when i get the time for it, but im probably going to buy a real arduino.

I dont mind paying extra for the real deal :P
i will just have to make sure its a 16u2 and not a 8u2 but i guess all rev 3 has 16u2?

i will report back once i get my hands on a new arduino.

[NicoHood]

All rev3 (official ones) have a 16u2 so you are at the secure side. Good idea to support the developers!

FYI: march 28th is Arduino day. I think a lot of shops offer sales. So you should have a look then (this saturday). Sparkfun, Adafruit and Seeed looks promising (for international shops, also see local sellers).

[thesymbol]

Ah thx, then i dont have to worry that i get a different chip. I love the arduino so its a no brainer to support the developers :P

Ok I will look for deals on the 28th then :D

[chandran13]

Greetings

I am chandran from Chennai India I get the following error can you pl help not very good on electronis or programming

Arduino: 1.6.3 (Windows 7), Board: "Arduino Uno"

HoodLoader2_Installation_Sketch.ino.ino:218:35: fatal error: bootloader_atmega16u2.h: No such file or directory

compilation terminated.

Error compiling.

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

regards
chandran

[NicoHood]

What chip do you want to use? 8u2 or 16u2?
Have you changed anything in the sketch?

It compiles for me, not sure what you are doing wrong. In the IDE you must see several tabs with different .h files.

[chandran13]

16u2

I have not touched any thing in sketch

[NicoHood]

Issue opened. Looks like an avrdude bug. And I cannot imagine of any clean solution for this. I could compile the hex file for the at90usb82 and mark it as an 8u2 (as you have it right now) and change the boards.txt. Since avrdude wont be updated in the IDE (even if they'd have a patch) there is no other way to fix it.

You have time to play with it now. can you also test if the IDE uploading now works (edit the baords.txt and set the at90usb82 mcu instead).

[thesymbol]

i will give it a shot as soon as im back at my computer.

[NicoHood]

Looks like an avrdude configuration file issue.

[NicoHood]

Thx for all the help.
So today we found 2 bugs. And both make HL2 not work with 8u2 or at90usb82 :D
I'll wait for some feedback from them now.

HL2 > Lufa (fixed in HL2, not yet in lufa itself, affected at90usb82)
HL2 > Arduino > avrdude (has to be fixed on one of those projects, affected atmega8u2)

[thesymbol]

Glad i could help with figuring this out 👍

EDIT: changed the boards.txt and added the special version of the at90usb82 and i can compile in the gui now aswell! thanks alot for this.
Will have to reflash once the bugs are fixed in avrdude 👍

[NicoHood]

Cool. Any bugs you noticed? I tent to push this to master soon.

What about Windows 10 drivers? Does it work natively?

[thesymbol]

No bugs so far, other than i cannot fit the entier USBCore on the 8u2 (not enough space to store it).
And there was no need for drivers on windows 10.

[NicoHood]

Oh sure, space could be a problem. You can use it without usb or without serial I think.
Thx for the infos!

[thesymbol]

It works without USB atleast when i try and compile in DFU mode in Arduino IDE. and i can get the LEDs to blink and get some output from the chip without problem.

[NicoHood]

Could you do me a favor? I need a screen shot of the window that pops up if you try to install the Teensy driver:
https://www.pjrc.com/teensy/serial_install.exe

Do not fully install it, abort it but take a screenshot with Control + Print please. There must pop up two windows. A welcome window and a windows "do you really want to install" like window. Please shot both. You can drop the pics here in the github comment. That'd be nice, because I dont have a windows system here.

[thesymbol]

Sorry for being so late to respond.
sadly i have already installed it on my machine so i can not take screenshots of it.
It is possible to do it through a virtualmachine, but if you can wait a while i might be able to take some shots off my laptop when im done installing windows on it again :)

[NicoHood]

Nevermind, played with win10 today.

[thesymbol]

Oki, sorry that i couldnt help.

[NicoHood]

at90usb82 support now got added. the problem with avrdude is still there though.

Can you please try to force upload the bootloader to your 8u2 (better use the at90usb82 bootloader and modify the installation sketch a bit, I trust in you that you can do that) and upload this sketch then:
https://github.com/nickgammon/arduino_sketches/tree/master/Atmega_Self_Read_Signature

Can you please report your signature then?

[thesymbol]

I will see what i can do, but I do not have the time to do it today, might be able to do it tomorrow tho.

[thesymbol]

i have forced the at90usb82 hex to upload to the arduino now, no problem there but im having trouble making the signature reading scetch to fit onto the 8u2's 4096 byte memory. (the scetch is 15592 bytes large).

[NicoHood]

hahaha damn. Well I contacted atmel now. If they dont respond I will ask Joarg wunsch again for patching avrdude anyways. for now there is no better solution and its not a bug of the hoodloader2 itself.

[thesymbol]

well i managed to get it down to around 5000 bytes but it looks like the usbcore is still uploading (taking away around 3000 bytes). so the program should fit onto the 4096 bytes of memory if i dont have to upload the usbcore.

[NicoHood]

place #undef USBCON inside arduino.h and replace serial with serial1. you need to read the data via the RX pin of the uno from another board/ftdi device.

[thesymbol]

After doing some tinkering i now cant compile the .ino file, getting

In file included from C:\Users\thesymbol\Desktop\Atmega_Self_Read_Signature\Atmega_Self_Read_Signature.ino:35:0:

exit status 1
Error compiling.

this happened when i did a clean install of arduino ide 1.6.6

[NicoHood]

which ino file? which nightly build? For me it works with the IDE from yesterday, recompiled myself

[thesymbol]

Arduino 1.6.6 Hourly Build 2015/09/28 05:01
and the self read signature ino file, it complains about <avr/boot.h>

[NicoHood]

Seems like an avrlib problem. Can you please post your fully modified sketch somewhere? Via github repository, via fork of this repo is maybe the best idea.

Very interesting.

[thesymbol]

Here is the modified version of the ino file: https://gist.github.com/thesymbol/483dcdbd88f057d2d3eb
i removed the md5 functions since that was taking up around 10kb, and it didnt have any problems before i did a clean install.

[NicoHood]

What did your setup look like before?

[thesymbol]

i used an older version of the nightlies, but i do not have that left sadly. it was the old PR version atleast that is what i know, and i installed the hardware manually. (HoodLoader2 folder in the Arduino folder in Documents).

[NicoHood]

Closing as this is an avrdude problem. Information can be found in this issue.
