Hi,

I am using Jflash 4.8 to program my KL02  chip, but the option "Secure Chip" in project settings is not seems to be working. I can still read back all the flash contents afterwards. Any idea what should I do? Should I program the register in my program?

Thanks

Sam

Hi Sam,

If customer want to program Flash configuration field, there need to set [--enable_config_write] parameter for Segger J-Link debugger tool.

More detailed info, please check below picture:

So, I think J-Flash tool also with similar parameter setting.

Wish it helps.


Have a great day,
Ma Hui
