Just a note about STlink when not usb powered
When i power the FR401 board with external power source, the stlink red led blinks and that's normal behavior. I'm also powering an external opamp with 3,3v out of the nucleo, which i read with ADCs. Problem is the ADC gets "offsetted" values everytime the stlink red led fires up. I put a removable jumper on SB11 (reset of stlink) to turn it off, so i don't care anymore, i just wanted you to know that. In case in future stlink firmwares the red led will stop blinking after few times, i think the analog people will be happy :)
