Hi,
I am trying to make Linux work on omap 850 based board which has an ARM926EJS. I have u-boot ported and installed on it and minimal
linux
support for the board is also there. The kernel image is in format expected by u-boot and I have followed all the needed steps like using mkimage etc. While uncompressing the linux image the system hangs, in gunzip function which is defined in inflate.c. No error is returned,
One possibility is that you have your sdram not well configured.
Do you
have a lowlevel debug in linux? Regards Michael
I dont think so, since I have re-checked it. I tried with a new kernel image and now I am getting gunzip error :
I am making the image as
6# mkimage -A arm -O linux -T kernel -C gzip -a 0x10009000 -n "Kernel Image" -d linux.bin.gz uImage.cc Image Name: Kernel Image Created: Wed May 9 16:02:57 2007 Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 1200234 Bytes = 1172.10 kB = 1.14 MB Load Address: 0x10009000 Entry Point: 0x10009000
and then I do bootm 0x10009000..
Booting image at 10009000 ...

Is it because of I am having wrong addresses?
It is a arm 926 based board.

I had similar problems on my board. U-Boot work fine, but the Kernel hangs on different places for different images. My fault was the configuration of the row and column address width.
regards, Stefan
Hi Stefan,
Can you explain a little more about the configuration of the row and the column address width?
I don't know your system. I used a XScale PXA270 with SDRAM and have to set the register for the memory controller. I make a mistake by setting the "Column Address Bits" and "Row Address Bit Count" to wrong values.
