OMAP L137 RAM disk File

Hello,

I am trying to bring up OMAP L137 evm board. 

I have flashed DSP , ARM and Uboot bin files to the SPI flash. uboot works fine.

I tried to copy kernel and RAM disk file to the SDRAM and board comes up.

But when I tried to do the same with SPI flash, the system doesn't come up.

The problem is size of the flash(4MB).

initial for DSP ARM and Uboot occupies around 200kb of memory.

Kernel requires 2MB.

and also  ramdisk.gz requires 2.6MB of memory.

but we don't have that much memory in the Flash.

My questions are,

1) is there any other ram disk file that I can use and boot.

2) How to create the Ram disk file

where will I find the RAM disk file for the OMAP L137 board.

Thanks And Regards,

Vijay Hiremath
