Thanks for pointing this out. 😄

Thanks for the detailed report! I don't have an H743, but will try to replicate on my H747.

I went ahead and got a Nucleo-H743 😄, and can reproduce the problem now even for small images. For testing, I'm using a build of Zephyr samples/basic/blinky ([attached](https://github.com/pyocd/pyOCD/files/7094424/h743_zephyr_blinky.zip)). It looks...

Thanks for the update, and for the willingness to help out. This one has been on my priority list for too long. I've been working on a script to fully...

@nvincent-vossloh Thank you for the test files! I've run `test_flash_algo.py` and it passes. However, it doesn't directly test programming yet, it currently does that as a side effect of testing...

Yup! I'm working on removing six, a little at a time. I think the only remaining uses are `ensure_bytes()` and `ensure_str()`.

It looks like this is baked into the J-Link SDK API, which uses an int for the serial number instead of a string. If you notice in a tool like...

Notice that the Segger tools all present the serial number without leading zeroes. This is from JLinkConfig.app:

@dnsglk How are you specifying the serial number on the pyocd command line? There may be two separate issues here. The `JLinkException` error is interesting since it doesn't include leading...

Ok, thanks. I'll replicate that and test on both Mac and Linux. (Glad to see you're using the API, btw!)
