Can you explain in words what you're expecting and what you're seeing instead?

I want to set 0x3A40EAAA in address 0x1FFF7800, and all zero in address 0x1FFF7870 (because BOOT_LOCK is set by default).

I see that the first 32bit+32bit complemented are flashed, but the other are not flashed..

Now after a power off I can't communicate with the ST.. I think it got stuck..

Any help please?

Thanks.

It sounds like you had one problem, and now you can’t even connect to ST-link which is another problem. If that’s the case, your board is likely dead. Not sure about the original issue.
