I have a JN5169 kit. It is lock CRP level 1.
I tried to use JN51xxProgrammer.exe to write crp level0 but it return "Error: one time programmable data has already been set in this device"
Can you help me handle this problem?
What are the commands that you are using?
Remember the CRP Level 1 - Flash read protection
The contents of internal Flash memory cannot be read via the bootloader serial interface. However, the internal Flash memory can still be erased and written
Please look at the 3.4 Load Binary File, Verify Write and Erase EEPROM
