Yes, you are correct, uImage is sizeof(vmlinuz)+sizeof(dtb)+64. > This doesn't appear to have actually used your initrd, despite you > having loaded one above, in particular there is no "Unpacking > initramfs..." message and none of the expected logging from the > initramfs. > > I'm not sure why this should be.

After interpolation, it's roughly equivalent to usb start; ext2load usb 0:1 0x6400000 /boot/uImage; \ ext2load usb 0:1 0x6800000 /boot/uInitrd; \ bootm 0x6400000 0x6800000 The problematic configuration (which I guess worked with wheezy as a no-op?) included an ext2load of /boot/dtb and passing that address to bootm. -- To UNSUBSCRIBE, email to debian-arm-requ...@lists.debian.org with a subject of "unsubscribe".
