Hi Looks like there is some problem in mapping of serial port interrupt. Because after booting the kernel serial port will work in interrupt routine.Now u have to verify two things :
1. in openpic what is the interrupt vector for serial port. 2. Same interrupt vectupr u have to program in ur serial.h file..... may be u will have a success if not send me ur sandpoint_setup.c & openpci_irq.c & kernel booting message. Thanx Bhupi Linux +HyPERtransport --->Silicon www.gdatech.com --- John Traill <john.traill at motorola.com> wrote: > > I'm having problems getting linuxppc-2.5 running on > an X2 Sandpoint system.
