Hi,
I am trying to use one Maix longan (nano) to debug another one. The VS code project to do this is here
But when doing an upload from platformio I get this error (I put more debug on the line for the key name)
KeyError: ‘Invalid board option ldscript build.ldscript’:
The project comes with a platformio, and a build.py
Platformio
; PlatformIO Project Configuration File
;
; Build options: build flags, source filter, extra scripting
; Upload options: custom port, speed and extra flags
; Library options: dependencies, extra library storages
[env:sipeed-longan-nano]
platform = gd32v
;framework = gd32vf103-sdk
board = sipeed-longan-nano
monitor_speed = 115200
upload_protocol = dfu
debug_tool = sipeed-rv-debugger
