Why do I see the message "Failed to load "dual_core_ds5.axf"" when using DDR?

[maxkotula]

I followed the instructions in the "Vybrid DS-5 Getting Started Guide" on how to setup an example project in ARM DS-5 to have the tower board use the DDR. I got this working but then decided to add #include "arm_math.h" to the vectors_m4.c file and got the below error:

ERROR(CMD16-TAD274-NAL20):

! Failed to load "dual_core_ds5.axf"

! Failed to write 11,088 bytes to address S:0x80000000 while writing block of 4,096 bytes to address S:0x80000000

! Verify error on memory operation.

I deleted the #include "arm_math.h" and I still get this error. I checked my file system and see the .axf file at the location used by the "loadfile" command. Is this a bug in ARM DS-5?

This issue was resolved by the fix suggested by the freescale support engineer from a support ticket I submitted. See below:

First of all accept our apologies for the delay,we have been swamped.

Let me see if I get this correctly.

1. 1.- You were able to debug and load an applicaion with the DDR correct?
2. 2.- But sometimes you are not able to connect to the device. Just after disconnecting the debug session.

We have seen this problem many times, it is related to CMSIS DAP and DS-5.

And it was even more frequent in DS-5 v 5.15. In case you are using this verion please  locate the file

  ..../Program Files/DS-5/sw/debugger/configdb/Boards/Freescale/Vybrid VF6xx/rddi-dap-cfg_osda_cmsis_vybrid.txt

and in section [cmsis-dap-cfg] change

  Clock=1000000

to

  Clock=500000

Thanks,

Hello

I'm facing the same issue with ARM DS-5 v5.18, I tried several Clock values with no success. I get the following error :

ERROR(CMD16-TAD274-NAL20):

! Verify error on memory operation.

I also tried to write on the DDR using the memory tool. I'm able to read it and sometimes to write some zeros but most of times i get an error :

Do you have any idea on the origin of this issue ?

Hello Max,

We have heard of issues when using DS-5 5.17 with building MQX projects; it may not be related to what you are experiencing, but we would recommend using DS-5 5.16 for now.

I was unable to locate the sample project you reference - can you share its source, or upload the sample project with your modifications?

Thanks,

Timesys Support
