Hi all,
"Wish You A Happy New Year".
I am trying to port Linux on PPC405GP. I have downloaded
linuxppc_2_4_devel using BitKeeper and compiled using powerpc-linux- tools.
And I followed the following steps to compile kernel.
make walnut_config
make mrproper
make menuconfig
make dep
make uImage
After exucuting final step, vmlinux.UBoot has been created in
/linuxppc_2_4_devel/arch/ppc/boot/images.
Boot Loader: I am using U-BOOT-0.4.0 as a boot loader.
Board: Custom Board with IBM walnut405 features.
U-BOOT is working fine. I have downloaded vmlinux.UBoot into 0x400000
memory location using tftp command. After I boot linux using command bootm
400000, it hangs after
PPC:> bootm 400000
## Booting image at 00400000 ...
Image Name: Linux-2.4.23
Created: 2003-12-23 10:11:20 UTC
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 258050 Bytes = 252 kB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
id mach(): done
MMU:enter
MMU:hw init
MMU:mapin
What could be the problem? Any suggestions are apreciated.
My board info is as follows:
PPC:> bd_info
memstart = 0x00000000
memsize = 0x04000000
flashstart = 0xFFF80000
flashsize = 0x00480000
flashoffset = 0x0002D000
sramstart = 0x00000000
sramsize = 0x00000000
bootflags = 0x0000A000
procfreq = 266.660 MHz
plb_busfreq = 133.330 MHz
pci_busfreq = 33.332 MHz
ethaddr = 00:01:01:01:01:01
IP addr = 192.168.0.204
baudrate = 9600 bps
And environment variables are set as follows:
PPC:> printenv
bootcmd=bootm F0400000
loads_echo=1
ethaddr=00:01:01:01:01:01
bootdelay=50
filesize=80000
ipaddr=192.168.0.204
serverip=192.168.0.65
baudrate=115200
bootflags=0x00000001
bootargs=root=/dev/ram0 rw
stdin=serial
stdout=serial
stderr=serial
Environment size: 238/65532 bytes
With Best Regards,
Nag
