1. Re: Checksum Failed
bob.marlowe Dec 1, 2012 7:42 AM (in response to engineer.dpto.i+d)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.

How Can I disable checksum?

bob.marlowe Dec 1, 2012 11:45 AM (in response to engineer.dpto.i+d)Don't know exactly, did you try to disable verification in the PSoC programmer ?

engineer.dpto.i+d Dec 2, 2012 10:19 AM (in response to engineer.dpto.i+d)Hi Bob,
Yes I try to disable verification, but the error appears.
I think this error could be caused by 'Doing Protect' action, after programation is corfirmed. Is posible disable it?
I dont find where.
Thanks

bob.marlowe Dec 2, 2012 10:35 AM (in response to engineer.dpto.i+d)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.

engineer.dpto.i+d Dec 2, 2012 2:12 PM (in response to engineer.dpto.i+d)Hi Bob,I have detected the problem but is very strange.When I'm using the computer with a high comsuption of resources (like compiling a linux kernel) and then I try to program a PSoC, checksum process is OK, but when resources are free, checksum fails.???It seems be fine when works slowly.Is posible reduce the programming velocity ? Or do some similar?Thanks -

bob.marlowe Dec 2, 2012 3:06 PM (in response to engineer.dpto.i+d)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.

arvi Dec 4, 2012 9:22 PM (in response to engineer.dpto.i+d)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.
Regards,
Arvind

nikhil.chandwadkar Mar 3, 2014 2:25 AM (in response to engineer.dpto.i+d)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.

bob.marlowe Mar 3, 2014 4:34 AM (in response to engineer.dpto.i+d)What hardware, which board, which PSoC, which programmer and which software version are you using?

13. Re: Checksum Failed
bob.marlowe Sep 15, 2014 2:53 PM (in response to engineer.dpto.i+d)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)

14. Re: Checksum Failed
syth.ryan Apr 16, 2015 1:31 PM (in response to engineer.dpto.i+d)I as well get this
Verification of "Protect Area" is FAILED!
Programming Terminated
===> Protect Failed
Doing Protect
I used to have the checksum fail until I turned everything in flashsecurity.txt to "U" or unprotected. I've also tried changing which aquire mode I'm in and have verification off. Any ideas?I'm using Mini Prog3/1229DD000931
