Hello all I have problem with MIPS4KECR2 and int handler, MIPS 4KECR2 has support for external interrupt controller. AFAIK, conditions for EIC mode are next: Config3(VEIC) = 1 IntCtl(VS) != 0 Cause(IV) = 1 Status(BEV) = 0 IntCtl(VS) has to be different then zero and this field specifies spacing beetween vectored interrupts. Interrupt handler for MIPS4KECR2 is placed on 0x80000200 and if I set IntCtl(VS) on 0x20 and I want to use max number of interrupts (63) I have to place almost 2k from 0x80000200 and I am afraid that I will overwritten something. I am pretty shure that I do not see obviouse things, but any help/comment will be most welcome. Best regards Mile
