Here is my progress,

I’ve found ac6 repository for openocd at git://git.ac6.fr/openocd.
Last tag on st branch “st_2.8.0” matches the git hash 5352c55 of installed openocd used by eclipse.
- The fact is that this version doesn’t seem to compile because of calls to JIM old API...
- Once compiled, stm32l4x.cfg tcl file isn’t enough to connect to target because of bad DEVICEID
- Finally, with a custom stm32wbx.cfg openocd connect, then freeze when trying to flash with command openocd -d3 -c “program binFile.bin verify reset exit 0x8000000” or openocd -d3 -c “program elfFile.elf verify reset exit”

Thank’s for your attention, if someone has information about this I’ll be pleased to hear of.

PS: I’ve attached my modifications patch to this message
PPS: Same error is reproductible with a stm32l4 (Nucleo board in my case)

Finally i managed to get it working

Using official repo https://git.code.sf.net/p/openocd/code
Then applying to patch corresponding to these commits:
- https://sourceforge.net/p/openocd/code/ci/2e8b2c4e516c5eef4790688840c2f2fb956bc46a/
- https://sourceforge.net/p/openocd/code/ci/0018081ed3cb1200e74d9911e66f1edf72e75579/
Finally including tcl script in the cfg file:
source find interface/stlink-v2-1.cfg
source find target/stm32wbx.cfg

I put commits patch as attachement
