STM32G0 Option Byte

[lorenzo meneghello_2]

Hi all,

I'm trying for the first time the new STM32G071RBT6, I'm looking to set the correct option byte via the .s file but something is wrong..

Thanks for help.

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.
