Well considering that this left saving settings broken for a year or so, I had no choice but debug this. Regarding linked branch, there are some minor concerns: 1. Critical...

I think it's safe to close this one as USB hubs are indeed not supported. It would likely only happen if [ST USB stack](https://github.com/STMicroelectronics/stm32_mw_usb_host) adds supports for hubs at some...

I think that error message is returned if you try to flash firmware when the firmware is running. You can only flash bootloader from firmware or firmware from bootloader. You...

>It is quite possible to flash the bootloader from the main firmware directly, if we decide to implement that. But flashing bootloader from firmware is supported (thanks to me!). Did...

Is it an actual loop or you just go to bootloader mode once? The former is not expected to happen as we have some code that should keep you in...

Yeah this sounds good, it looks like that would let us distinguish packages that have successfully returned from upload begin procedure. I can test and make a PR for this....

Maybe we can change handleFirmwareUpload to ignore intermediate packages silently. I.e. we could have the error message about corrupt sysex stream to be generated only when last package (that would...

I would be surprised if changes go much further than tweaks to some peripherals. I.e. kernel patches mention that GPIO banks can be secured, whatever that means.

ST have added product pages and documentation for MP13x chips. A comparison to MP15x is available here - https://www.st.com/resource/en/application_note/an5475-migration-of-applications-from-stm32mp15x-lines-to-stm32mp13x-lines-microprocessor-stmicroelectronics.pdf They also offer a discovery kit for it - https://www.st.com/en/evaluation-tools/stm32mp135f-dk.html
