my cpu is MPC860, use u-boot-1.1.4, linux-2.6.20.14 i use the "tftp 300000 uImage" command download kernel image,
then use the "bootm 300000" command boot the image. i found the bootm cmd entered the /arch/ppc/kernel/head_8xx.s, stop at the instruction "rfi". is it right? after the instruction, where does the code go normally ? what should i do now? thanks .globl __start __start: mr r31,r3 /* save parameters */ mr r30,r4 mr r29,r5 mr r28,r6 mr r27,r7 /* We have to turn on the MMU right away so we get cache modes * set correctly. */ bl initial_mmu /* We now have the lower 8 Meg mapped into TLB entries, and the caches * ready to work. */ turn_on_mmu: mfmsr r0 ori r0,r0,MSR_DR|MSR_IR mtspr SPRN_SRR1,r0 lis r0,[EMAIL PROTECTED] ori r0,r0,[EMAIL PROTECTED] mtspr SPRN_SRR0,r0 SYNC rfi /* enables MMU */ poorbeyond 2007-07-27
