Hello there,

I'm trying tu use the system memory bootloader, but the nucleo never enter in this mode. in the AN2606, the note says to use pattern 8 and quotes about boot(pin) and BOOT_ADD0/BOOT_ADD1. I tried put boot pin in high level voltage and restart microcontroller, but the board doesn't enter in bootloader mode. Can you help me about this?

How do you know it's not entering the bootloader?

I have connected a conversor usb-ttl to UART1 pinout and trying to send 0x7F and there isn't returns to the terminal.

have you resolved your problem ?

Why don't you use the Flasher software available on the STM site ?
