I'm attempting to build a linux kernel (3.4-rc4) for the AM/DM37x Evaluation Module. I built my own cross tools using CrossTools-ng (gcc4.4.3, glibc2.9, binutils2.21.1a). I am using the bootloader that came on the board and booting from the mmc card. Below is the output I get at startup.
Should I be attempting this from the tmlind git tree instead of stable?
Could someone send me a .config file from a known working kernel? I am dreadfully ignorant about ARM processors, having spent the last 12 years as a PPC guy. I now have this ARM eval kit sitting on my desk that I really need to get working in short order. :)
Thanks,
--Mike

Your kernel is probably booting, but without serial console output. What
does U-Boot pass as the serial console parameter? If something like "console=ttySx"
then it might be the issue. With this recent kernel try passing "console=ttyOx"
instead (where 'x' is the UART number).
HTH,

Thank you...you are correct, Sir. I changed the console to ttyO0 and now have output. I am having issues trying to mount the RFS that is on the MMC card but have not fully investigated that issue yet.
I would still really like to see a OMAP3_EVM .config file if anyone has one available.
Thanks,
