Trouble with openocd-v0.12.0

[41exey]

When I updated openocd to 0.12 I'm to face a problem:

Open On-Chip Debugger 0.12.0 (2023-01-14-23:37)
Licensed under GNU GPL v2
For bug reports, read

Info : auto-selecting first available session transport "swd". To override use 'transport select <transport>'.
Error: CMSIS-DAP command mismatch. Sent 0x0 received 0x3
Error: CMSIS-DAP command CMD_INFO failed.

In 0.11 version it wasn't:

Any ideas?

Hello @41exey!

The error message suggests that there is a command mismatch between the CMSIS-DAP interface and OpenOCD 0.12.0. One possible solution is to try changing the session transport from SWD to JTAG by using the transport select jtag command.

Could you do this and tell me if a change was presented please.

Best Regards!

try changing the session transport from SWD to JTAG by using the transport select jtag command.

I changed transport to jtag but same error. Nothing has changed.

Hello @41exey !

It seems like there may be an issue with the compatibility between the version of OpenOCD being used (0.12) and the CMSIS-DAP protocol on the device.

In the meantim, I suggest continuing to use version 11 of OpenOCD, However, I will put the bug tag in the issue to check it and see the root of the problem.

Thank you for bringing this to our attention.

Good Day!
