Checksum Failed

This forum software is a bit weired, so can it be that we have to read the lines from bottom up?

If so, it seems to be correct: The last thing you (the programmer) do is burning some last fuses, so that the contents cannot be red out ("protect") This implements that a checksum cannot give a correct result since nothing meaningful can be red back from that point on. Solution? Try to disable check-summing the device.

Don't know exactly, did you try to disable verification in the PSoC programmer ?

Bob

There is a file named "flashsecurity.txt" shown in the workspacwe explorer. Edit this file accordingly to unprotect your flash-areas if you want to.

This looks a bit weired now, better try to file a technical case (under "Support -> Technical Support -> Create a Case" at the top of this page) to get some Help from Cypress directly.

Yes, this does sound weird.. 

Do you have a spare system which you use to program your device? That will help you make sure it's the PC/software that is causing the problem.

Did you ever find out what was causing the problem?  I am getting the same error. Sometimes, the device does get programmed, but sometimes I get the error.

What hardware, which board, which PSoC, which programmer and which software version are you using?

 Hello

I have the same problem, the following message appears

You do not have a checksum faillure, but a protection faillure.

I would suggest to

First: switch off all protection completely and verify programming and project working correctly.

later: start switching on protecction which afaik cannot be verified (due to the protection)

Bob

 I as well get this

Verification of "Protect Area" is FAILED!

Programming Terminated

===> Protect Failed

Doing Protect
