Hello everyone, i want to get bootloader working through USART protocol. I looked to the datahseet and it says, that BOOT0 should be 1, and BOOT1 0. Since BOOT1 here isnt and I/O pin, it has to be programed and i found out, that it is an optinional byte, but by default it should be 0. So all i need to do is to connect BOOT0 pin to 3V supply and push reset button, and system memory boot mode should be selected. I downloaded the STM flash loader program but i cant get that to work because i always get an answer: No response from the target, the Boot loader cannot be started. Could someone explain me what im doing whrong here and why bootloader doesn't start? Thanks in advance.
