DS-5 Debugger : How to add peripherals memory mapped registers of a Freescale i.MX25 ?

Joël Esponde

Hi,

I am debugging a software in a board based on a Freescale i.MX25 CPU.

But default debug configurations does not embed the memory mapped registers of the peripherals of the CPU. I am not able to see the peripherals registers value.

I have tried to create a tcf file from a bcd file coming from the older RealView Development Suite, but I am stuck there.

Is there a way to add this tcf file to my debug configuration ? Or is there another way to see the peripherals registers (other than memory viewer) ?

Thanks !!

    Hi there,

    Are you asking how to specify the tcf file to the debugger? To do this, use the Debug Configurations Pane, Files tab, and select 'Add peripheral files from directory':

    If you are asking how to generate the tcf, see chapter 3 of the DS-5 User Guide.

    Hi,

    That was exactly what I was looking for !!

    I was unable to find this information in the debugger user guide.

    Thanks a lot !!

    Hi,

    With the previous information, I managed to load a tcf file in a debugging session. The list of registers appeared correctly. But there was an error when trying to look at the content.

    Since 3 month, I did not work with the peripherals of the imx25.

    Now, I am trying again to make them work. I created a very simple tcf file thinking that it would help to find the solution, but it also fails. I joined it to the post.

    Two types of errors appear. The first one is logged in the command console when starting debugging session :

    WARNING(CDB53): Read only memory maps cannot be modified, ignoring new region - SDRAM0

    WARNING(CDB53): Read only memory maps cannot be modified, ignoring new region - SDRAM1

    The second one is logged when trying to look at the content of a register :

    Target Message: This version of debug hardware does not support physical memory addresses for this core.

    I can see the content ot the register by using directly the address inside the Memory view (in my case 0x53FF8000).

    But when DS-5 accesses to the memory by using this address &($Peripherals::$P_CSI::$G_CSICR1) or P:0x53FF8000, it fails to load the content.

    Does anyone have an idea on the problem that makes DS-5 fail to display memory mapped registers of imx25 ?

    Thanks !!

    Hi Joël,

    I think you would be better off contacting ARM technical support directly - they can test your .tcf file out on the correct hardware and hopefully find a solution.

    Thanks,
