Checksum Failed

engineer.dpto.i+d Apr 23, 2015 4:53 PM

Hi,

when I try to program a code example on multifunction expansion card with FTSK programmer, I always receive the next programming log:

Programming Terminated

===> Checksum Failed

Doing Checksum

Doing Protect

Programming Succeeded

Programming Starting

Erase Succeeded

Silicon: 0038, Family/Die: 15, Major Rev: A

>>>Program Requested

PSOC seems is programed correctly but this error always appears.

Can someone help me?

Thanks

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 ?

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.

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.

    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

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?

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)

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
