Arduino for STM32

Fine.

Hi All.
I install last Arduino IDE (2.1) and last STM32 core (2.5.0) on a Windows 10 64 bit.
Install the Arduino SAMD Boards (32-bits ARM Cortex-M0+) from Board Manager.
I used ST-Link v2 and tried to debug Blink on BluePill board. I am getting an error:

Error: timed out while waiting for target halted
Error: timed out while waiting for target halted
Error executing event gdb-flash-erase-start on target stm32f1x.cpu:
TARGET: stm32f1x.cpu - Not halted
Error: Target not halted
Error: failed erasing sectors 0 to 8
Error: flash_erase returned -304
Error: timed out while waiting for target halted

Luca got the same error.
nrst pin is connected and work.

"reset_config srst_nogate" not apply !
Instead of the "reset_config srst_nogate" option, the "reset_config srst_only" option is substituted.

Hi all.

Following this link https://github.com/vsergeev/arm-bmw-sw/issues/1 I found that using reset_config none separate instead reset_config srst_only in file openocd.cfg (under variants directory), you can debug without connect reset pin to ST-Link programmer.
I tried using a Bluepill and it works.
Can anybody else confirm?
If it really works, can openocd.cfg file be updated with new reset_config setting?

Maybe you doesn't need to connect reset pin to ST-Link probe also if you cancel reset_config line from openocd.cfg file (in this way openocd will use default reset configuration).

Regards.

Hi Luca,
Having the same issue with an STM32F030C8 chip. Only way I can get debugging to connect at all is to hit the reset button while connecting. After it's connected though, nothing works unless I've disabled srst_only.

I tried getting this to work with IDE 2.3.2 ans STM32core 2.7.1 but no success loading the .svd so far
debugging itself works

I added debug_custom.json to the sketch folder and had it pointing to the SVD folder of STM32CubeProgrammer
As that did not work, I copied the svd to the sketch folder as well (and changed the json), but that did not help either

I also tried downgrade to 2.0.3, no luck with that as well

In fact since IDE 2.3.x, the debug has been reworked by Arduino.
I'm currently working to support the new way to support debug svd files.
