Mkag,
1) internal initramfs.
In the kernel source files, inside arch/arm/kernel/head.S
Line 272:
str r3, [r0, #4]! @ KERNEL + 1MB
add r3, r3, #1 << 20
str r3, [r0, #4]! @ KERNEL + 2MB
add r3, r3, #1 << 20
str r3, [r0, #4] @ KERNEL + 3MB
You can add additional lines to increase the acceptable kernelsize.
Every 2 lines will add another MB.
This is not a good solution, but it will work.
add r3, r3, #1 << 20
str r3, [r0, #4] @ KERNEL + 4MB
2) external initramfs.
Can you please post the u-boot line that is used to boot the kernel? I
assume you might miss something.
Regards,
Theo

Hi,
Have anybody tried the option of Initramfs instead of initrd in
DM6467 EVM for the kernel montavista 2.6.10?
I tried the uImage which contains initramfs to boot thorugh tftp with
bootargs as listed in the wiki.
http://wiki.davincidsp.com/index.php?title=Initrd
If Uimage is more than 2.4mb then it hangs after uncompressing the
kernel as shown below
## Booting image at 81800000 ...
Image Name: Linux-2.6.10_mvl401-davinci_evm-
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 2930000 Bytes = 2.8 MB
Load Address: 80008000
Entry Point: 80008000
Verifying Checksum ... OK
OK
Starting kernel ...
Uncompressing
Linux........................................................................................................................................
(Hangs here inifinitely)
If I try to use external initramfs using the cpio image avilable at
"dir: ...usr/" , it is telling bad gzip magic number.
Have anybody tried the option of Initramfs and succeeded in it in
DM6467 EVM for the kernel montavista 2.6.10?

Mahendra Kumar
