PSoC 4 protected to open mode

[Anonymous]

Hi

   

I was playing around with a psoc 4200 dev board and put one of them into protected mode. Documentation says I am able to change it back to open mode after erasing flash. I have tried calling the Erase All API followed by the Write Protection API but it does not seem to be working. 

   

Anybody can help to guide me on a step by step to change it back to open mode?

As long as you selected "Protected" a simple erase (when re-programming) will unprotect the chip.

   

When you used "kill" mode the protection is permanent and cannot be reverted.

Ok thanks a million I've got it fixed. I've tried it before on PSOC Creator but it didn't work. Tried it yesterday on PSOC Programmer with kitprog and it works.
