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

[Tommy M. <tom...@ho...>]

Sporadic connection/instability issues can often be caused by things like poor (or too long) wiring between the host PC/probe/target, unreliable power to the probe/target, clocking/timing issues etc.
So these are all things that might be worth eliminating as relevant factors.

Also - if you can capture and post a verbose (openocd -d3) log for a failure case it may help to identify problems.

And if you're not already doing so you might want to build and use the very latest OpenOCD from the repo rather than using some older version from an OS software repository or other download source.
