why fault?
thanks。
Hi,
What is "fault"? Have you erased UICR prior to trying to write?
Please have a look at this post.
Best regards,
Jørgen
Did you follow the suggested code in the post I linked? You need to enable writing in the NVMC peripheral before you are allowed to write UICR from code.
yes,I tried the first answer in the post. And I measured the voltage turn to 1.8V. So far so good, but the voltage stay at 1.8 no matter how I change the value REGOUT0.Maybe there should be some extra handle?
sincerely.
