MCB2929 board not detecting in Keil

nidhi sriv

Hi,

I wrote a code for MCB2929 using keil uvision4. In debugging mode my code was getting stuck somewhere in startup code. So i commented one line in startup code

 USB_IRQ_H_Handler
   USB_IRQHandler
                B       .
                ENDP
 

 

I commented third line i.e. "B  ." and loaded the code using ulink2.
Now the board is not getting detected by keil. I undo the changes but still the board is not getting detected in keil. Can anyone suggest me regarding the same.

Thanks

    The board is. dead or some problem with the board
    No, the board is not dead. The problem is with the software.

    if I try to erase the flash it says cannot erase when cpu is running.
    That means software needs to be modified.

    The board is not detecting in keil.
    I assume you are saying in debugging mode. Keil is IDE, not an interface.

    If you have any working code, generate a hex file and program using ISP.
    Advise: Never play with startup code or header files unless you know what you are doing.
