Uploading to AVR using Raspberry Pi GPIO (avrdude GPIO reset)

FAQ
42

I am trying with

env.Replace(UPLOADER="/usr/bin/avrdude")

that is the version avrdude default for raspberry pi and linuxspi programmer if it is available, but platformio does not detect it

I’ve just checked and it works for me

pio run -t program -v

  1. Please verify that you use extra_script.py above
  2. You should use program target
  3. The script should contain env.AddPreAction("program", before_upload).
  4. Try uploading with --verbose.

Working, but I have the next error

scons: *** [program] /sys/class/gpio/gpio22value: Permission denied

I am run with sudo

sudo pio run -t program -v

45

Could you try to restart RPi?

46

Yes, if not restart i have the next error

scons: *** [program] Device or resource busy

47

Please try to disable “after” uploading

# env.AddPostAction("program", after_upload)
48

Same error
scons: *** [program] /sys/class/gpio/gpio22value: Permission denied

Could you flash this board without PIO?

Working!!

My platformio.ini is:

[env:attiny85]
platform = atmelavr
framework = arduino
board = attiny85
board_f_cpu = 800000
upload_flags = -C /etc/avrdude.conf -P$UPLOAD_PORT -b 10000
upload_protocol = linuxspi
upload_port = /dev/spidev0.0
extra_script = extra_script.py

Thanks!

Aaaaa /etc/avrdude.conf :slight_smile: Yep, the config also should be used a correct.

My congrats! That was really interesting for me to resolve this task with PlatformIO. Now I understand how is PlatformIO powerfull :blush:
