my cpu is 860T, using bootm command boot a linux kernel image, the following message print by smc1:
bootm 300000
## Booting image at 00300000 ...
Image Name: Linux-2.6.20.14
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 1081591 Bytes = 1 MB
Load Address: 00100000
Entry Point: 00100000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
## Current stack ends at 0x01D5DB10 => set upper limit to 0x00800000
No initrd
## Transferring control to Linux (at address 00100000) ...
then, the program has no response.
i debug it througth BDM, in u-boot function "do_bootm_linux", execute at "kernel = (void (*)(bd_t *, ulong, ulong, ulong, ulong))hdr->ih_ep", the program branch to address "0x00000000", the code is shown as following:
00000000 mr r31,r3
00000004 mr r30,r4
00000008 mr r29,r5
0000000C mr r28,r6
00000010 mr r27,r7
00000014 bl 0x000020C8
00000018 mfmsr r0
0000001C ori r0,r0,0x30
00000020 mtspr SRR1,r0
00000024 lis r0,0xC0002004@h
00000028 ori r0,r0,0xC0002004@l
0000002C mtspr SRR0,r0
00000030 rfi
my questions are:
1. Is the code "kernel = (void (*)(bd_t *, ulong, ulong, ulong, ulong))hdr->ih_ep" branch right?
2. What's the expected code after "kernel = (void (*)(bd_t *, ulong, ulong, ulong, ulong))hdr->ih_ep"?
3. When the kernel run to the "boot/simple/head.s"?
thanks a lot
