OpenOCD config results in error #10

Using the openocd.cfg/openocd.gdb in the repo I get the following error:

Tried multiple board resets and only reverting it back to the original cortex example (modified for the f40x) restored the connection.

No idea, sorry. I've been using OpenOCD only for flashing but even that is obsolete now.

@arkap Any idea?

Sorry, I don't know either. The config works fine on my machine.

@therealprof Out of curiosity: What are you using instead of OpenOCD to flash and debug?

therealprof commented 4 years ago

For flashing I use cargo-flash from the probe-rs project: https://probe.rs/

I don't do debugging but in theory that should work with probe-rs, too.
