I am trying this approach now. I created a bootable USB (well, theoretically bootable, I haven't actually managed to boot from it) using `bmaptool`. However, I am not sure how to boot from it from the U-Boot console. I tried loading the `fitImage` in the /boot and run `bootm` to boot (I am just trying random things at this point, I am not really sure what I am doing) but the kernel panics. The steps I have done: * Run: `usb start` * Load the `fitImage` into memory: `load usb 0:1 $loadaddr /boot/fitImage` * Boot: `bootm` Then the kernel panics with the following error message > > /dev/root: Can't open blockdev > VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6 > Please append a correct "root=" boot option; here are the available > partitions: > 0100 65536 ram0 > (driver?) > 0101 65536 ram1 > (driver?) > 0102 65536 ram2 > (driver?) > 0103 65536 ram3 > (driver?) > 0104 65536 ram4 > (driver?) > 0105 65536 ram5 > (driver?) > 0106 65536 ram6 > (driver?) > 0107 65536 ram7 > (driver?) > 0108 65536 ram8 > (driver?) > 0109 65536 ram9 > (driver?) > 010a 65536 ram10 > (driver?) > 010b 65536 ram11 > (driver?) > 010c 65536 ram12 > (driver?) > 010d 65536 ram13 > (driver?) > 010e 65536 ram14 > (driver?) > 010f 65536 ram15 > (driver?) > b300 7634944 mmcblk2 > driver: mmcblk > b301 134010 mmcblk2p1 076c4a2a-01 > b302 7496704 mmcblk2p2 076c4a2a-02 > b308 4096 mmcblk2boot0 > (driver?) > b310 4096 mmcblk2boot1 > (driver?) > Kernel panic - not syncing: VFS: Unable to mount root fs on > unknown-block(0,0) > What am I missing here?
