PSOC5 is unsecure!!!

Postby psocExperimenter » Thu Aug 01, 2013 1:59 am

System settings option "Device protection" is not working
This is response from CYpres:
" It was considered as dangerous for now and not implemented"
Without this option the code can be view and debugged easily ( in assembly)
I can't forget marketing folders "POSC3/5 is a new step in chip security"
The story go on with POSC4 now

I have received another clarification from Cypres support.
However I don't understand a bit.
"1):Do the programmer option "Chip Lock" in options work?
A): If the key of WO NVLs is in hex files and you set the programmer option "Chip Lock" , it will work.
If the key of WO NVLs is not in hex files and you set the programmer option "Chip Lock" , it will not work.
2):The F1 manual says" The result depends on content of hex file"
What does it mean?
A): It should write the key of WO NVLs into the write once NVL, the key is in the hex file after compile the project. If the key of WO NVLs is in hex files and you set the programmer option "Chip Lock" , it will work. The reason that you set the programmer option "Chip Lock" and the chip doesn't be lock, because we didn't write the key into the WO NVLs.
3): The only way to use the function of WO NVLs is to write PPCLI script to update WO-NVLs manually. please refer to my previous reply.
"
Does anyone know how to make "Chip Lock" it work?

Hi Bob,

Thanks for pointing this out. I am checking with our Programmer team internally to find out the exact procedure to do it. After getting their confirmation, I will update the forum post with the exact procedure to use WO latch.
