Hello all,

I'm new in using STM32 microcontrollers.
I have my own board with a STM32L051 microcontroller and I need to use the bootloader.

I've a jumper to the BOTT0 pin to set to hight or low.
I don't have change anything on the nBOOT1 bit.

My probleme is that when I set BOOT0 pin to hight, connect the USART1 to my computer, the Flash Loader Demonstrator tool don't see the STM32L051.

I've check with a serial spy, my computer send the code "0x7F" but no answer from my board...

May be I've missed something during configuration or other...

Is there some one to help me ?
Thanks in advance !!
