My pogoplug only have 2 mtd devices

Postby stackbear » Fri Aug 01, 2014 9:00 pm

Hey guys,

My pogoplug is a E02 device (in a black case though), with uboot-pogo_e02 (2014.04.R4-1). And there are only 2 mtd devices:

dev: size erasesize name
mtd0: 00100000 00020000 "u-boot"
mtd1: 07f00000 00020000 "rootfs"

Therefore I cannot install doozan's rescue system since the installation script is expecting mtd2 as well.

Is it normal for my pogoplug to have only 2 mtd devices?

Thanks!

No, it's not "normal". The default partition layout for E02 is the follow:
mtdparts=mtdparts=orion_nand:1M(u-boot),4M(uImage),32M(rootfs),-(data)

The mtd partition is configuration via the "mtdparts" uBoot environment variable. Not sure if the uboot installation process you used set the partition back to the default.

#see the current layout
fw_printenv mtdparts

#set it back to the default
fw_setenv mtdparts 'mtdparts=orion_nand:1M(u-boot),4M(uImage),32M(rootfs),-(data)'

reboot and install the rescue env.

Last command should be fw_setenv, but it is recommended to overwite default settings in /boot/uEnv.txt if applicable (like in this case)
Code: Select all
echo 'mtdparts=mtdparts=orion_nand:1M(u-boot),4M(uImage),32M(rootfs),-(data)' >> /boot/uEnv.txt

Good catch @hydro. It was a cut/paste error. :)

I believe OP will want/need to set the mtdparts env directly in nand versus the uEnv.txt because OP is planning on booting the rescue system directly from nand.
