Add support for STM32U595/5A5

[jerabaul29]

I have a nucleo with a stm32u5a5 chip https://www.st.com/en/evaluation-tools/nucleo-u5a5zj-q.html . It seems like I cannot communicate with it using probe-rs:

kzm@kzm-bpq:~$ probe-rs --version
probe-rs 0.20.0
git commit: crates.io
kzm@kzm-bpq:~$ probe-rs chip list | grep STM32U5A5
[no hit]

I am doing anything wrong or is it correct that this chip is not supported at present? What would need to be implemented to support this chip (if it is a few trivial changes I could try to give it a look), and / or could support for this chip be added? :) .

A smart comment by @gauteh : for now I get, using a "close family" chip kind instead of the "true correct" STM32U5A5:

Error: This capability has not yet been implemented for this architecture: vector catch

Can this mean that the program actually gets flashed and executed, and "only" the debugging is missing? I should check later today!

probe-rs should already support U5A5. See #1744 Try git version:

cargo install probe-rs --features cli --git https://github.com/probe-rs/probe-rs

Many thanks @burrbull for the help! I just installed as you indicated, and I can indeed see the boards in the list now :)

probe-rs chip list | grep STM32U5A5
        STM32U5A5AJHx
        STM32U5A5AJHxQ
        STM32U5A5QJIx
        STM32U5A5QJIxQ
        STM32U5A5RJTx
        STM32U5A5RJTxQ
        STM32U5A5VJTx
        STM32U5A5VJTxQ
        STM32U5A5ZJTx
        STM32U5A5ZJTxQ
        STM32U5A5ZJYxQ

I don't have the board available just now, will test program upload tonight :) .

Many thanks for your help, this does work fine now :)
