Re: [OpenOCD-user] Anyone using STM32U5 with OpenOCD?

[Rob M. <Rob...@u-...>]

Interesting: attached find the [non-debug I'm afraid] log output from a success case using OpenOCD with the Zephyr west tool, plus the openocd.cfg file it employs.

In the openocd.cfg file it does indeed say:

# Reset configuration
# use hardware reset, connect under reset
# connect_assert_srst needed if low power mode application running (WFI...)
reset_config srst_only srst_nogate connect_assert_srst

However, if I power the board down entirely and modify the reset_config line in my own stm32u5.cfg file to be the same as this I still, unfortunately, get the problem.

There's something I'm missing here...
