Hello,
I am designing a card that will use an STM32G474QET6TR and I want to program it using USART.
The card will use a USB to USART converter (FTDI4232HL).
The Rx and Tx of the FTDI are connected to pin PA2 and PA3 respectively, as I found in AN2606.
My first question is how can I tell my MCU that it is supposed to use bootloader mode ? and Which pattern would be better to use ? Also, regarding the pattern, how do I tell the MCU that nBoot1(bit) is supposed to be a 1 or a 0 ?
I am quite lost regarding how the bootloader works and any docs I've read as made me even more lost ?? So any help provided will be most welcome.
Thank you very much
