Bug? PlatformIO Esp32 doesn't upload via serial in debug mode

PlatformIO IDE

For some reason the PlatformIO environment doesn’t upload the debug build it creates when trying to enter debug mode (Run->Start Debugging) - for me at least. It will build it, but never uploads it. I’m using the esp-prog tool for debugging but want to keep the serial upload for circuitry reasons.

I can serial upload either release or debug builds fine when building/uploading, it is only during the debug sequence that it doesn’t upload.

This is my platform.ini:

[env:esp32thing_plus]
upload_port = COM19
platform = espressif32
board = esp32dev
framework = arduino
build_type = debug
monitor_speed = 115200
debug_tool = esp-prog
debug_init_break = tbreak setup
build_flags = -DCORE_DEBUG_LEVEL=5

Note I need the upload_port specified there as during regular upload platformio will incorrectly autodetect the esp-prog port and try to upload to that…

Any thoughts?

When you start a debug session, what does the “Debug Console” tab in VSCode say? There is critical info there.

Most likely you haven’t connected the debugger to the board correctly per this article.
