Hello,
I'm using blhost to write IFR 0x80 to put device into unsecured state. To do this I must set bits 1:0 in FSEC register to 10. Since blhost requires 4 or 8 bytes, I am guessing the value I should write is: 0xFFFFFFFE (0xE = 1110). I also tried little endian 0xFEFFFFFF. It did not work either.
When I read back 0x80 after writing, it looks like it worked. When I reset the device (or cycle power), the state is SECURED. But I expect it to be UNSECURED, since I wrote 10.
What am I doing wrong?
Thank you
