I have an STM32F746 evaluation board and I want to acces the system bootloader. According to the User Manual, chapter 5.5, all I have to do is to flip the switch and use USART1, on the DB9 connector CN7, to communicate with the loader. I have tried a couple of things.

  1. Acces with the Fload Loader Demonstrator, both the executable and the CLI. I get the following message
  2. Acces with a terminal program and sendingcommands according to AN3155, but I get no response, whatever I try.


Does anybody have any tips to establish the connection?


Thanks in advance.
