Platform IO cannot locate “ upload_port” . In configuration.h do l simply add
#define_ upload_port com xxxx . Is there a numbered line to add it to or simply any where ? Have spent many hours trying to upload VS CODE . To MKS GEN L board. Cheers
Per PlatformIO documentation, this is a configuration option of the platformio.ini
file.
If you open Marlin’s platformio.ini
file, there should be a default_envs = ..
at the top. Take that name and search for the corresponding [env:<name>]
section in the file. There you can put the option.
