STM32H743XX HIC

[gaborcsapo]

Hi, please find below the changes for the STM32H743XX HIC that we've been working on. There is also an extension of of the usual DAPLink code in the "source/hic_hal/stm32/stm32h743ii/extended_features" folder which are used by the UDB (Universal Debug Board) stm32h743ii HIC. The additional features include:

• A new USB CDC endpoint to flash and get logs from a second target.
• Another new USB CDC endpoint to interact with the HIC. Users can send easy shell commands to toggle pins, or to get any info from the HIC.
• Additional DAPLink debugging functionality: persistent fault info, breakpoints on asserts when debugger is connected to debug UDB, watchdog, backtraces
• Target power measurement

Let me know how you'd like to review these changes. We touched the common code only to fix bugs and to change USB CDC stack to support 3 endpoints. If needed, I can give a demo of the UDB features.

Hi @gaborcsapo, this pull-request needs to simplified. One of the first step would be to rebase the branch to remove all duplicated commits (due merge from main/develop or cherry-picked). Second step would be to re-group and possibly squash commits into different categories:

• Changes that modify existing code / other HIC
• Adding stm32h743ii HIC (generic part)
• Adding UDB board source (source/hic_hal/stm32/stm32h743ii/extended_features should probably be source/board/udb) and tests.

@mathias-arm, finished with cleanup. I hope this is what you meant.
