Unable to upload code to Arduino Nano (using Arduino IDE works) #108

Closed AlbertEmil closed 5 years ago

AlbertEmil commented 5 years ago

I am using an Arduino Nano (Clone) which I was programming with the Arduino IDE (Version 1.8.5 on Mac OS X 10.10.5).

Using the Arduino IDE I need to re-plug the Nano before uploading, but after doing this everything works as expected and the sketch is being uploaded successfully.

I then tried to use Platformio core (CLI) and get the well-known not in sync error:

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

As said, this error is well-known, esp. in relation to Arduino clones, and reported several times around the Internet with different solutions.

I just wonder how Arduino IDE is able to upload the code successfully, but Platformio is not since both Arduino IDE and Platformio CLI are just calling avrdude to upload the code.

Just to make sure the installation of Platformio is working as desired I switched to an Arduino Uno board, added the additional environment by platformio init --board uno, compiled the code and uploaded it which works like a charm (with Arduino IDE as well as Platformio).

I enabled verbose output for both Arduino IDE and Platformio to get the exact avrdude command executed to upload the compiled hex-file. I then adopted the call to avrdude from the Arduino IDE with the path of the compiled hex-file:

avrdude -v -p atmega328p -c arduino -b 57600 -D -P /dev/cu.usbserial-00000000 -U flash:w:.pioenvs/nano/firmware.hex:i

Using the Arduino IDE's avrdude call to upload the hex file which was built by using Platformio works as desired, so I had a look at Platformio's call to avrdude which is slightly different form the Arduino one and provides an additional config-file with passing the -C option (neglecting possible pre-upload scripts here):

avrdude -v -p atmega328p -C /Users/Albert/.platformio/packages/tool-avrdude/avrdude.conf -c arduino -b 57600 -D -P "/dev/cu.usbserial-00000000" -U flash:w:.pioenvs/nano/firmware.hex:i

Unfortunately, I am not able to run this command from the Terminal by myself due to an error:

         System wide configuration file is "/Users/Albert/.platformio/packages/tool-avrdude/avrdude.conf"
avrdude: syntax error at /Users/Albert/.platformio/packages/tool-avrdude/avrdude.conf:1080

Arduino IDE's version of avrdude is packed with the Arduino IDE itself and uses a config-file in the etc subdirectory of the Arduino application directory. Since I am assuming that the error might come from different config files, I compared both. The only difference in the ATmega328 section is an additional

part parent "m328"
    id          = "m328pb";
    desc        = "ATmega328PB";
    signature       = 0x1e 0x95 0x16;

    ocdrev              = 1;
;

in Platformio's config-file.

For the sake of completeness I should mention that I have three different versions of avrdude installed on my system:

Please use board = nanoatmega328new in your platformio.ini.

AlbertEmil commented 5 years ago

Neither nanoatmega328new nor nanoatmega328 did do the trick on my Mac. However I was able to upload/flash the code to both of my tested boards with using PlatformIO Core (CLI) on Fedora 29. Due to that, I assume that this issue is not related to the boards itself (from a hardware perspective), but more an avrdude issue of PlatformIO since using Arduino IDE's version of avrdude, if you can call it that way, is working as expected.
