Hi ST Community,

I'm wondering if there's a sample project for a UART Bootloader for the NUCLEO-H755ZI-Q series.

Thanks for your support

Do you mean a custom bootloader over UART?

PS: I don’t see why posting this question in CubeIDE forum board!

I think the question was "custom bootloader" vs the System bootloader in ROM ?

So custom bootloader:

System bootloader:

      Why don’t use the ST bootloader like indicated by the application notes provided above?
