Problem with the bootloader startup file(LPC2378)

Hi

We have two different projects bootloader(without RTX kernal) and Application code (with RTX Kernal).When we laod the bootlaoder and the application code, part of the RAM data will be corrupted.Please guide to resolve this problem.

Software interrupts is not required for the bootlaoder
we have not shifted the interrupt address, we are using the same interrupt address

Meomory mapping is as below
Bootloader 0 - 0x2000
Application code starts from 0x2000

Thank you
Harish

  • Hi,

    Thanks for your reply..

    Only 3 bytes of the buffer is getting corrupted.
    The buffer is of size 200 bytes, it is used for communication between the boards
    The Corrutped location is alomost at the centre of the buffer,the corruped location is almost at the centre of the buffer.

    We have already verified the above in the map file, it is not getting corrupted due to the overflow or underflow of any other variables
