Support for STM32U5

[daniel-merrick]

Are there any plans to add support for STM32U5 NUCLEO boards?

The STM32U5xx parts are supported via the Keil.STM32U5xx_DFP CMSIS-Pack unless there is a strong reason to have built-in support, like the Packs don't work. (CMSIS-Packs are the preferred way to add new targets unless there are barriers to doing so.)

Note that I haven't yet been able to test with a U5 since I don't have a board (yet).

Ah I see - So I download the Keil.STM32U5xx_DFP.1.1.1.pack from https://www.keil.com/dd2/pack/#!#eula-container then pass ''--pack=Keil.STM32U5xx_DFP.1.1.1.pack'' to the PYOCD command.

Thank you!

Actually you can use pyocd pack install u575 to install the pack and not have to download it manually. This also makes the target types available without needing the --pack argument.

The target support documentation has all the details.

Installing like that doesn't seem to work properly: This is the error I receive

pyocd pack install u575
0000741 W No matching devices. Please make sure the pack index is up to date. [pack_cmd]

That's odd. I just tried it again and it worked fine, even without have a pack index installed previously. I guess it's possible you have an out of date pack index from before the U5xx pack was added?

Please try adding -u or --update to the command line: pyocd pack install -u u575. This will ensure the pack index is up to date before checking (you'll get a bunch of warnings for XML formatted errors in the numerous packs).

You can also try: pyocd pack clean ; pyocd pack update, then run the install command. This will completely erase and re-download the pack index before attempting to install. (It should be more or less equivalent to the -u argument, but could fix an index that was somehow corrupted.)

The second method did seem to work however the first failed. Here are outputs of both in case others run into the same problem:

here is the output of the first try:

Thanks again!

Very interesting! Thanks for trying and I'm glad it worked eventually…

One strange thing is that the warnings are different between the 2 pack updates, and also different from my own tests.
