[sp] This is definitely not the right place. The question belongs to
 linux-omap mailing list.

[sp] You have shared no information on versions of x-loader, u-boot and
 kernel. How is your custom board different from any known platform
 omap3evm, beagle, sdp, ...

 In absence, you should look at your customizations and ensure all
 board specific hook-ups or changes are properly handled in software.

[sp] Provide more details and move your kernel related queries to linux-omap.

[U-Boot] omap3 booting issues

2010-11-19 Thread Murali K. Vemuri
Hi there,

This may not be the ideal place to post this question, but I thought
someone might know this.

I have custom board using OMAP3 and I have a problem. We have more
than one I2C slave connected on I2C1 & u-boot was not displaying the
slave addresses correctly.

I fixed some issues in u-boot  and am finally able to see the u-boot
displaying the I2C devices correctly.

But after this Kernel stopped to boot. It just gives the message:

Starting kernel ...

Uncompressing 
Linux...
done, booting the kernel.

and stops.
I tried to find out  the possible reason, but no use so far (about 2
days).  Currently my MLO (x-loader), u-boot.bin, & the kernel uImage
reside on the SD Card .
BTW, I found a curious comment in the kernel code: /* First I2C bus is
not muxable */
Can this be a problem for the board not booting?
As I had been playing with I2C only, I had to dig mainly on the I2C
direction. any other pointers will be helpful
Thanks & regards
Murali
