Remote debugging works for stm32 , remote download fails

PlatformIO Core
#1

Platformio on Lubuntu , config project

upload_protocol = custom
upload_port =  limero.local:3333
debug_tool = custom
debug_port =  limero.local:3333
debug_build_flags = -O0 -ggdb3 -g3

I can do remote debugging to a raspberry pi running openocd with this config

lieven@limero:~/workspace/hoverboard $ more ocd-server.sh 
sudo openocd -f openocd.cfg
lieven@limero:~/workspace/hoverboard $ more openocd.cfg 
bindto 0.0.0.0
source [find interface/stlink.cfg]
set CHIPNAME stm32f1x
source [find target/stm32f1x.cfg]
init
targets
reset halt
# program testProgram.hex verify reset
# shutdown

When I use remote debug ( F5 ) it uploads code and I can debug, when doing the download , it doesn’t connect to the openocd and doesn’t transfer the image.

PlatformIO has built in remote uploading capabilities if you use PIO Remote.

The OpenOCD upload will always try and invoke OpenOCD locally (source), setting a remote upload_port where a GDB server opened by OpenOCD is listening doesn’t change that. You would have to write a custom upload protocol command that invokes GDB with the right commands to flash the firmware on the device.

That was quick ! Didn’t expect an answer anytime soon.
I’ll have a look at PIO remote.
Thanks !
