PCIe MSI generation on MPC-8640 as RC

Question asked by shubhanginisingh on Oct 21, 2013

I am working on MPC-8641, and facing a problem regarding the handling of msi transaction in u-boot.

I am unmasking the vectors and initiating a msi transaction by writing to msiir register of pic which in turn call my bootloader's external interrupt handler

and prints the messages which i had given in handler but after executing that it just hangs.

If any one is having any idea please reply.
