Hello,
I am currently using the EZSDK v6.00.00 to boot linux from USB. I followed the directions listed here (http://processors.wiki.ti.com/index.php/AMSDK_u-boot_User%27s_Guide#Booting_Linux_from_USB_storage) but can't seem to load Linux. I have used the create-sdcard.sh to partition and format my USB drive. I have also confimed that the rootfs partition has the file system.
We are currently using the AM3352 processor on a custom board.
Here is my print out from the linux kernel:
-Boot# fatload usb 0 ${loadaddr} ${bootfile}
