hello, i download and install ti-sdk-am3517-evm-06.00.00.00-Linux-x86-Install, then run "make linux_clean", "make linux" and "make linux_install", after that i download to ram using uboot "loady" command at 0x82000000 (or 0x80008000), after that "bootm 0x82000000 (or 0x80008000)".

Mariano,
Please include your current U-Boot environment.

Mariano,
Your 'console' environment variable is incorrect. It should be:
console=ttyO2,115200n8
run these commands to change it and retry:
AM3517_EVM # setenv console 'ttyO2,115200n8'
AM3517_EVM # saveenv

I change console, but still the same hang

Mariano,
Print out your bootargs before you call bootm. I don't see where you are setting them.

Mariano,
The problem is that you are not passing any bootargs to the kernel.

You can do this in several ways. Take a look at the following two lines from your environment.
mmcargs=setenv bootargs console=${console} root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait
nandargs=setenv bootargs console=${console} root=/dev/mtdblock4 rw rootfstype=jffs2
You will need to specify the console, root mount point and other rootfs parameters. What kind of rootfs are you going to use?
