Code Read Protection (CRP3) with MCB2300

edward fang

I use CRP3 function in my firmware with MCB2300 demo board. When I download it to MCB2300, then I can't upload another firmware again. How do I solve this problem ?

Thank you !!

    Mmmmm.....

    Personally, I think the USB secondary ISP bootloader for LPC23xx example from NXP is danger.

    Its behavior of CRP3 destroys the last chance to update the ARM7 SOC.

    Hi Edward,

    If you have some time, you should futher check the documents and source codes to see if there is still some way to rescue your MCB2300.
