Hi @Antonio Borneo,

Many thanks for your reply, and the time you spend to help me out.
I can send you an SWDAP probe.
Or I can send you the funds over PayPal so you can buy one directly from the 
store:
https://www.l-tek.com/web-shop/l-tek-swdap-interface/

Please let me know what you prefer.

Many thanks :-)
Kind greetings,
Kristof Mulier

Hi Kristof,

I have seen the messages about the daplink issue, but without the
adapter I though I cannot do that much, so I dropped it.

I have read again all the threads (very quickly, I have to admit) and
also downloaded the daplink code from
https://github.com/armmbed/DAPLink
It is a special implementation of CMSIS-DAP for mbed.

The original FW you had in your board was a v0244 or older, because
OpenOD recognizes it as
Info : CMSIS-DAP: FW Version = 1.0
This string has been changed in DAPLink FW file
source/daplink/cmsis-dap/DAP.c with commit
https://github.com/ARMmbed/DAPLink/commit/48417e9f8541f51bf2ca2e26a7ee69c5fcb34b80
so the newer FW you have tested v0252 and v0253 report
Info : CMSIS-DAP: FW Version = 1.10
and both do not work with OpenOCD. I don't have a cmsis-dap v1.10 to
verify if there is already something wrong in OpenOCD.

The DAPLink FW v0254 adds many changes. Between them it stops
reporting the CMSIS-DAP version "1.10", reporting instead the DAPLink
version "0254".

Checking the code of DAPLink, looks like it is possible to recompile
it for STM32F103 (ST-Link)!
Maybe I will have a look at it using an old Nucleo board, but it will
depends on my spare time.

Or maybe some other OpenOCD developer could take this reply as a hint.

Antonio
