CodeWarrior DDR Validation BIST tests issue

[danmoffatt]

Hi

Can anyone explain whty the four DDR Validation BIST test types fail to execute and the colour coding indicates "..............error in the test script"?

I am able to successfully excute the DDR validation stage and the other four DDR Validation test types (DMA Test, Write-Read-Compare, Walking Ones and Walking Zeros).

I have successfully run 20 test runs of the DMA Test, Write-Read-Compare, Walking Ones and Walking Zeros tests multiple times without out any failures.

Please see attached image for clarification.

please send two capture the DDR register dump via ccs, one after a BIST test fails and one after a DMA test that passes.

How to get register dump via ccs
This is for debug use only.
1) Open a CCS window (C:\Freescale\CW4NET_v2016.01\Common\CCS\bin\ccs.exe)
2) Physical connection: USB to PC, JTAG to the customer board.
3) SW connection: in the ccs window type:


delete all
config cc cwtap
ccs::config_chain {ls1043a dap sap2}
display ccs::read_mem 32 0x1080000 4 0 1024
ccs::write_mem 32 0x1080FB0 4 0 0x10000000
display ccs::read_mem 32 0x1080000 4 0 1024

Hi

The four BIST DDR validation tests started failing to execute again

I am working with an LS1088A processor so the commands you sent (shown below) don't work for me. Can you please provide equivalent commands pertinent to an LS1088A?

Thank you!

Please refer to the following CCS commands.

display ccs::get_config_chain

display ccs::read_mem <sap position> 0x1080000 4 0 1024

Hi

I uninstalled all CodeWarrior SW and projects from my PC. Then I reinstalled the CoceWarrior SW and created a new project from scratch.

The issue was resolved and the all DDR validation tests are now functional.

Thank you for your efforts!
