Hi, I am trying to boot the T1040RDB in 64-bit mode and am encountering a problem.
First, I configured a yocto environment for 64-bit "fsl-setup-poky t1040rdb-64b" and built my images.
Next, I'm trying to do a tftp boot using the exact same method I can use successfully with the 32-bit build but with the 64-bit images instead. The steps are described in section 11.2 of the QorIQ T1040 RDB Quick start. Basically, I load my 64-bit uImage into 0x1000000, the rootfs into 0x200000 and the dtb into 0xc00000 and finally do a bootm.
After I run boot I get the following console output with the error on the final line:
Bytes transferred = 5103719 (4de067 hex)

If I just tftp over the dtb file to 0xc00000 and examine it using the fdt command from u-boot everything looks fine.

Any ideas what is going on? Is it okay that u-boot is in 36 bit addressing mode or do I need to rebuild part of the flash?
Thanks, Jake
