Hi,
i´m trying to use OpenOCD with Olimex ARM USB Interface to get access
to a Freescale i.mx53 Controller. I get access via JTAG an can halt the
Controller.

The halt command also works well:
********************************************************************************
> halt
number of cache level 2
cache l2 present :not supported
mpdir not in multiprocessor format
target state: halted
target halted in Thumb state due to debug-request, current mode: Supervisor
cpsr: 0x200001f3 pc: 0x00405ee4
MMU: disabled, D-Cache: disabled, I-Cache: disabled

********************************************************************************
I can read the internal SRAM with the mdw command. But if i want to read GPIO
Registers
i get an Error like this:
********************************************************************************
> mdw 0x53f88000 1
Block read error address 0x53f88000
in procedure 'mdw'
>
********************************************************************************
Could someone please help me to get access to i.mx53 Registers?
