RM48HDK

Hi,

We're Currently working on RM48HDK using GreenHills Multi IDE development tools. When we tried to access the internal flash and Peripherals memory map MULTIIDE not able to write those memory locations.

Can anyone suggest  what could be the reasons if MULTIIDE (Jtag Probe) is not able to access the internal flash and Peripherals memory map.

Regards,

Brahmam.

    Hi Brahmam,

    This question can be best answered by someone from the Green Hills support team. The on-chip flash cannot be directly written using the debugger. Rather this is done by a program that uses the flash API provided by TI to erase/program the on-chip flash.

    If you have the tool set up correctly you should be able to write to the SRAM locations as well as to peripheral control registers (once the peripheral reset is released). You need to set bit 8, PENA (Peripheral Enable) of the Clock Control register (CLKCNTL) at address 0xFFFFFFD0 in order to release the peripheral reset.

    Try writing to addresses 0x08000000 onwards and let me know if the write works correctly.

    Regards,
    Sunil
