Hi

I'm setting up U-Boot 1.3.2 on a PowerPC 405EP based prototype board. The execution stops shortly after returning from 'interrupt_init()' on line 998 in 'lib_ppc/board.c'. When I comment out this function call or line 104 in 'ppc_lib/interrupts.c' (set_msr(get_msr() | MSR_EE) I get the U-Boot prompt. All interrupt sources are disabled in 'board_early_init_f' and should therefore not make problems (I hope at least, that I did it correctly):

mtdcr(uicsr, 0xFFFFFFFF); /* clear all ints */ mtdcr(uicer, 0x00000000); /* disable all ints */ mtdcr(uiccr, 0x00000000); mtdcr(uicpr, 0xF7FF7F00); /* set int polarities */ mtdcr(uictr, 0x00000000); /* set int trigger levels */ mtdcr(uicsr, 0xFFFFFFFF); /* clear all ints */ mtdcr(uicvcr, 0x00000001);

So my assumption is that the board crashes on the first occurance of the PIT interrupt, but I am not sure.

Has anybody seen something similar and could give me a hint?

Thank you in advance, Reto
