Hello everybody

I am trying to disable read out protection (level 1) on my stm32f407-discovery with flash loader demo (v2.6). I've connected Boot0 to Vdd, PB2 (boot1) to Gnd and my serial port (via max232) to usart1 PA9 and PA10. When I connect to PA9 led7 turns green. The flash loader demo doesn't recognize my device. I've also tried with usart3 (led7 is turned off) but the result is the same.

Hi

I tried the 2.6.0 flash loader on my stm32f401 based pcb, but it shows only stm8 devices in the selection box .... I wonder if this tool ever worked for stm32... i am stuck on it

Myopic much? What ever the problem is, it's with how you're using it. Perhaps you can diagram your custom connectivity? BOOT0 must by High at reset. Make sure to be using even parity, and try sending 0x7F at 9600 8E1 from something like RealTerm, and see if you get an 0x79 response. PA9 USART1 is NOT usable on the STM32F4-DISCO because of a huge bulk capacitor attached to the pin.

Thanks for the reply.

I've managed to run the flash demo on my friends board I used the PB10 and PB11. My board is probably ruined (was playing with power supply some time ago).
