Hi,
I am using AM335x_sk. I tried taking the source from Linux-Next(http://git.kernel.org/?p=linux/kernel/git/next/linux-next.git) and received linux kernel version 3.7.0-rc8 kernel as the latest source. I compiled it using arm-arago-linux-gnueabi- provided along with the ti-sdk-am335x-evm and as per the instructions at http://processors.wiki.ti.com/index.php/AMSDK_Linux_User%27s_Guide.
I have partitioned my micro-sd card using the utility create-sdcard.sh provided along with the ti-sdk-am335x-evm for two partitions.
I used the prebuilt u-boot.img and MLO provided in ti-sdk-am335x-evm, but am unable to boot the kernel. It hangs at "starting kernel...." and no further messages are displayed.
For this I tried changing the console device from ttyo0 to ttyo1 and ttyo2 in bootargs. I confirmed that the Machine id is same as in mach-types in kernel.
I tried using the following bootargs
setenv bootargs console=ttyO0,115200n8 root=/dev/mmcblk0p2 rw rootwait rootfstype=ext3
The log is as follows
