Lost control of MCB2130

Alan Preuss

Hello,

I have run into a strange situation with the MCB2130 evaluation board. Over the past days I have written several test programs and have downloaded my code without problems using both JTAG (Ulink2) and using the serial port with Flash Magic. Both Flashing methods worked great. However I just downloaded another pre-written code into the MCB2130 and now I seem to have lost re-flashing capability. I have tried to erase using both Ulink2 and serial but I am receiving a no-communication error messages.

Any suggestions would be appreciated!

Thank you,
Alan

    Hi Per,

    Thanks for your reply.

    I reviewed the UM for the LPC2132 and the code protect section of the manual says

    When the code read protection is enabled the JTAG debug port, external memory boot
and the following ISP commands are disabled:
1) Read Memory
2) Write to RAM
3) Go
4) Copy RAM to Flash


    It seems the ISP flash erase should work to clear the processor to it's factory fresh state. However I can't get any of the ISP erasing to operate.

    Thanks,
    Alan
