  • Cannot access to CP15 on arm9

    Hi,

    We've tried to access to CP15 with JLINK PLUS probe on STA8088 (ARM9), by two ways :
    • Jlink commander and command "rce"
    • gdb server and command "monitor CP15 "
    With JLINK commander we obtained "Read Failed".
    With GDB we obtained none consistant value.

    In Init of JLINK commander we can see the ARM configuration (ARM9 .... ) got through CP15 operation of your probe.

    Could you clarify, initial condition ( reset & so one ), to get CP15 access operationnal.

    Thanks.
