I noticed that an5471 says that the uart interface for flashing the bootloader is only available on PA8 and PA9, but those pins aren't present on the 32 pin version. Is there any other way to access the bootloader on this device?
Thank you, I must have mixed up PA and PB when I was reading it before. Does it matter that uart isn't listed on those pins in the datasheet? It has usart instead for af0 for both pins.
