Just finished writing an ADC driver which I connected to a PPC via PLB (slave configuration). I have also instantiated a OPB interrupt controller to which I'm trying to register my ADC driver interrupt. However, so far I couldn't manage to register my interrupt handler--- SDK keeps on giving me this weird error message whenever I attempt to register my external interrupt through XExc_RegisterHandler API. The error messages is:
"cannot move location counter backwards (from fffff070 to 00000070)"
I'm using EDK 9.1.
Probably I'm missing something. Though it might be worth posting as one can never be sure in case it turned out to be a known issue or something.
Would appreciate any help in this.
