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, 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 Saving Environment to NAND... Erasing Nand... Erasing at 0x260000 -- 100% complete. Writing to Nand... done AM3517_EVM # .

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?
