I have RT809F that hate SST bios ics. i write it and it gave me Verification Error.

i see protection from Status register with 0x1C. i try to change register to unlock but not help. after change status register i can read and erase. but when i write i give verification error and after reading have status register again on 0x1C but chip is erased
