Hello,
I have some custom atmega328P board that have no bootloader on. I am using arduino IDE to burn a new bootloader with a UNO board.
Now, I want to use the burn bootloader of platformIO but I am not able to make it work even if I got a success message after burn bootloader.
What i don’t understand is that i have a success message whereas I am still unable to upload a simple program to my board. When I do the same operation with arduino ide. I don’t have those issue.
I don’t really understand if it is possible to burn bootloader whithout using a script suggest in this warning message :
Warning: The
customupload protocol is used! The upload and fuse flags may conflict!
I am just using the programmer “arduino as isp” used in arduino IDE too : Atmel AVR — PlatformIO latest documentation
With some extra argument such as :
board_hardware.oscillator = external ; added
board_build.f_cpu = 4000000L ;added 4 MHz
I got the following platformio.ini configuration
platformio.ini
[common_env_data]
platform = atmelavr
framework = arduino
src_filter = ${env.src_filter} +<bootloader.cpp>
[env:uno]
platform = atmelavr
board = uno
framework = arduino
[env:program_via_ArduinoISP]
platform = ${common_env_data.platform}
framework =${common_env_data.framework}
board = atmega328p
board_hardware.oscillator = external ; added
board_build.f_cpu = 4000000L ;added 4 MHz
upload_protocol = custom
upload_port = COM10
upload_speed = 19200
upload_flags =
-C

stk500v1
upload_command = avrdude $UPLOAD_FLAGS -U flash:w:$SOURCE:i
src_filter =${common_env_data.src_filter}
lib_extra_dirs =
/lib
If I try to understand what is doing burn bootloader:
- it first recognize the target device with its signature
- then it check the fuses
- finally it upload the bootloader
result after burn bootloader platformio
