Debug ARM7TDMI through DStream

Philippe Fouquet

Hi

I try to debug a old linux kernel (2.4) on a ARM7TDMI (samsung s3c44b0x).

I read some tutorial and forum discussion but nothing work.

Somebody know where can I find a good tutorial for debugging kernel on a ARM7TDMI from scratch?

Thanks for reply

P.S.:I try to create a new platform database but when I run a JTAG chain auto detection the system read correctly the IDCODE (0x1F0F0F0F), but it is affect to a unknown device and not to a ARM7TDMI.

    Hi,

    I am sorry to hear that.

    What you can do is if you manually add the ARM7TDMI when you run PCE instead (see below) :

     

    Save your config and then build it. This assumes that only the ARM7TDMI is on the JTAG scan chain.

    Then you should be able to debug it.

    I'll look into the issue you reported of the IDCODE 0x1F0F0F0F referring to an UNKNOWN device.

     

    Please let me know how you get on and if this helps.
