i made a quick tour on my m92 using

https://www.mobileread.com/forums/sho...89&postcount=5

i can see that the main disk is called /dev/mmcblk0 and it's splitted on tre linux partition (id=83) mounted a /, /root and /media/flash

The other disk being the external sd card.
So basically overwriting with dd the provided uImage-initramfs to /dev/mmcblk0 must be done as root and is a potential brick of the device.

I would like to mount -o loop the provided dd image on a linux machine on a mount point but i was not able.
Maybe my command is not correct.

mount -o loop,offset=32256 uImage-initramfs /tmp/
i have back
mount: unknown filesystem type '(null)'

i will feel more reassured if i can see the difference between the image and my current artatech system.
Maybe with a different tar archive for each of the 3 file systems to overwrite.
