[U-Boot-Users] Problem creating new uImage

[Markus Klotzbücher]

Dear List,

I'm facing a problem creating a new fdt image following the instructions
in the u-boot/doc/uImage.FIT/howto.txt

u-boot and dtc are top of git:

$ dtc -v
Version: DTC 1.1.0-g050e6f0c

~/src/git/u-boot/ $ git-describe 
v1.3.3-32-gf2aeecc

I'm in the linux-2.6-denx/ directory with kernel and target blob:

~/src/git/linux-2.6-denx/ $ ls target.dtb vmlinux.bin.gz 
target.dtb  vmlinux.bin.gz

I try to create the new image as follows:

$ ../u-boot/tools/mkimage -f ../u-boot/doc/uImage.FIT/kernel_fdt.its kernel_fdt.itb
FIT format handling
Trying to execute "dtc -I dts -O dtb -p 500 ../u-boot/doc/uImage.FIT/kernel_fdt.its > kernel_fdt.itb.tmp"
DTC: dts->dtb  on file "../u-boot/doc/uImage.FIT/kernel_fdt.its"
../u-boot/doc/uImage.FIT/kernel_fdt.its:11 syntax error
FATAL ERROR: Unable to parse input tree
../u-boot/tools/mkimage: Can't read kernel_fdt.itb.tmp: Invalid argument

Any ideas?

Thanks and regards

Markus Klotzbuecher

Hi Markus,

Line 11 of doc/uImage.FIT/kernel_fdt.its is:

data = /incbin/("./vmlinux.bin.gz");

So most likely your problem is due to mainline dtc not supporting binary
includes (yet). You need to patch it with original Scott Wood's patch,
see:

HTH,
Bartlomiej

That was it (and enabling CONFIG_FIT of course).

The new Image works nicely! Thanks!

Best regards
