I am working with a custom model powerpc board (750-based) and I am having an issue with icount.
First, upon the first execution of the rfi instruction, I get: qemu: fatal: Raised interrupt while not in I/O function NIP 00030354 LR 00000000 CTR 00000000 XER 00000000 CPU#0 MSR 00001000 HID0 0000c484 HF 00000000 iidx 3 didx 3 Bad icount read However, the interrupt controller is one I created and there is certainly no assertion of the CPU's external interrupt line. For reference, NIP is the first instruction in vxTaskEntry(). If I comment out the line of code that calls cpu_abort() in this case, everything works, but it runs very slowly under high interrupt load. (Once the boot-up serial console messages fly by, the system runs at a reasonable speed.) If anyone has any experience with these two issues I'd appreciate your knowledge. Steven
