Linux Kernel 3.12.13 Pogo V3 (Oxnas OX820) package and rootfs (Flattened Device Tree)

My latest FDT kernel package and rootfs for Pogoplug Pro V3 (with PCI).

With this kernel we can run the Pogo Pro V3 boxes with either old U-Boot version (stock U-Boot and its variants) or the latest U-Boot (e.g. 2013.10).

Background:
Booting Debian on Pogoplug Pro,
New uboot and kernel for Pogoplug v3/Pro


Requirements: Pogoplug Pro V3 running Debian rootfs.
Recommended: working serial console has been connected and tested.


Latest kernel: linux-3.12.13-oxnas-tld-4.2-bodhi.tar.bz2 (09 May 2014)
Latest rootfs: TBD

Updated 09 May 2014:

Kernel linux-3.12.13-oxnas-tld-4.2 package was uploaded.

Download at Dropbox:
linux-3.12.13-oxnas-tld-4.2-bodhi.tar.bz2
md5:
ddf820216c7be59740962a1011db2913

This tarball contains 4 files:

linux-image-3.12.13-oxnas-tld-4.2_4.2_armel.deb
zImage.3.12.13-oxnas-tld-4.2
config-3.12.13-oxnas-tld-4.2
ox820-pogoplug-pro.dtb

INSTALLATION:

1. Installation to run with new U-Boot in NAND (see new U-Boot thread here)

- Backup your rootfs to another USB stick or HDD.

- Boot into your Pogo V3 and change directory to:

cd /boot

- Backup your current uImage and uInitrd (if there is any). In the /boot directory, these are files for your current kernel (xx.xx.xx is the version number):
uInitrd
uImage
initrd.img-xx.xx.xx-kirkwood
System.map-xx.xx.xx-kirkwood
vmlinuz-xx.xx.xx-kirkwood
config-xx.xx.xx-kirkwood

- Extract the kernel in the archive:

tar -xjf linux-3.12.13-oxnas-tld-4.2-bodhi.tar.bz2

- Create a dts directory for the dtb (just for organization purpose)

mkdir dts
mv ox820-pogoplug-pro.dtb dts/

- And install it with dpkg. If you encounter error with flash-kernel when running dpkg, then remove flash-kernel first to avoid potential problem (It is much better to generate uImage and uInitrd manually anyway):

apt-get remove flash-kernel 
dpkg -i linux-3.12.13-oxnas-tld-4.2-bodhi.tar.bz2

- Create uImage and uInitrd manually:

mkimage -A arm -O linux -T kernel -C none -a 0x60008000 -e 0x60008000 -n Linux-3.12.13-oxnas-tld-4.2 -d /boot/vmlinuz-3.12.13-oxnas-tld-4.2 /boot/uImage
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x60000000 -e 0x60000000 -n initramfs-3.12.13-oxnas-tld-4.2  -d /boot/initrd.img-3.12.13-oxnas-tld-4.2 /boot/uInitrd

- Setup U-Boot envs:

Disclaimer: The following U-Boot envs settings are recommendation only. If you don't have serial console connected, please do not attempt. Be aware that changing U-Boot env settings to the wrong values will lock you out of the box until you can connect a serial console.

Your booting envs should look like below. These are only for demonstration for the correct load addresses (not to be cut/paste as is). However these are my current u-boot envs.

dt_usb_set_bootargs=setenv bootargs console=ttyS0,115200 root=/dev/sda1  rootwait
dt_bootm=bootm 0x60500000 0x60a00000 0x61c00000
dt_load_initrd=ext2load usb 0:1 0x60a00000 /boot/uInitrd
dt_load_uimage=ext2load usb 0:1 0x60500000 /boot/uImage
dt_load_dtb=ext2load usb 0:1 0x61c00000  /boot/dts/ox820-pogoplug-pro.dtb
dt_usb_boot=run dt_load_uimage; run dt_load_initrd; run dt_load_dtb; run dt_bootm
dt_usb_bootcmd=run dt_usb_set_bootargs; run dt_usb_boot
dt_bootcmd_usb=usb start; run dt_usb_bootcmd; usb stop; reset

- Sync and reboot. Double check your u-boot envs, make sure there is no error. Connect serial console/netconsole and monitor the boot log.

sync
reboot

2. Installation to run with stock U-Boot in NAND

TBD.
