STM32L452xx Bootloader on UART4

Associate II

I'm looking at AN2606, section 65.1 and it looks like UART 4 can NOT be used by the bootloader to load FW into the part. 

Can someone confirm that is true?


AN2606 is usually pretty definitive about such things.

Your own loader can do as it wants, and implement a standard protocol like X-Modem, that'll work out-of-the-box with many terminal apps.
