How to convert zImage to Image for GoFLEX Home (1 reply)

Bodhi,

Looks like ARCH Linux ARM (ALARM) has this ArchLinuxARM-armv5-latest.tar.gz and this ArchLinuxARM-kirkwood-latest.tar.gz. I am not sure what are differences between the two. I use the later one and that gives me problems, i.e. no SSH, can't detect SATA HDD, etc. Its /boot directory also contains no kirkwood-goflexhome.dtb file. OTOH, the former (ArchLinuxARM-armv5-latest.tar.gz) does contain the dtbs/kirkwood-goflexhome.dtb file with zImage (no uImage) file in its /boot directory. At any rate, I tried to boot my GoFLEX Home with the former. In that, I have to generate the uImage file from the available zImage as shown below. However, my GoFLEX Home just boots with a solid red LED. Perhaps, I did something incorrect in uImage generation. Can you please help?

mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n "Arch Linux ARM" -d zImage uImage

I don't have a serial console setup, but just netconsole which is shown below.
