STM Flash Loader Demo does not recognize my NUCLEO-F767ZI

I am trying to use the built in boot-loader on my STM32F767. I wrote a simple app on my PC and I can get sensible answers from GET, GET VERSION, GET ID commands. But when I try to do a GO or a READ, the address (I have tries 0x00200000, 0x08000000 and 0 addresses) is rejected with a NAK.

Note that the READ or GO command itself is not rejected so it is not due to RDP or anything like that.

Any ideas why would be greatly appreciated.

So I got the STM Flash Loader Demo app to try that and it doesn't recognize my device.

If I try again I get a no response message unless I reset my board.

Any help on this would also be greatly appreciated.

Hello @KDuff.15​ ,

The STM Flash Loader you are using does not support STM32F76x devices.

We recommend you to use the STM32CubeProgrammer software for programming STM32 products.
