7. Restore MAC address and other envs

Restore the MAC address using the saved envs in current_envs.txt. Or find the MAC address on the sticker outside the case. Replace xx:xx:xx:xx:xx:xx with the real values.

fw_setenv ethaddr 'xx:xx:xx:xx:xx:xx'
For sanity check, list you envs again
fw_printenv

You also want to restore other specific information such as ipaddr (IP address of this box, if you use static IP).

Don't reboot if there is error while listing U-Boot envs. Post at the forum for help.

fw_setenv netmask 255.255.255.0
fw_setenv gatewayip <your router IP address>
fw_setenv ipaddr <your box IP address>

4. Create uImage and uInitrd and setup for booting.

I'm using the GoFlex Net booting with USB drive as an example here. Please replace its name (kirkwood-goflexnet.dtb) with the box you are installing on (for example, kirkwood-pogo_e02.dtb). Please look inside the rootfs /boot/dts/ for the correct DTB file name for your box.

Below are the 2 different alternatives in booting (method 4b is required for booting with older U-Boot that does not support FDT, but should not be used if running latest u-boot).

- Choose option 4a if you are going to use the current rootfs for many different Kirkwood boxes, as is. It should boot most of the Kirkwood boxes. And with the latest U-Boot for Kirkwood that suports FDT (if you are installing both the new u-boot and rootfs for the first time, too). This is the preferred method.

- Choose option 4b (This method is required for booting with older U-Boot that does not support FDT) if you only use the current rootfs for the box you're installing on, and don't want to modify u-boot envs. Note that if you are installing from stock OS, u-boot envs must be modified to boot with USB or HDD (please see Boot Kirkwood rootfs with stock u-boot for how to set up the envs in serial console).

4a. Boot with DTB file (standard way to boot FDT kernel). Recommended.

Generate the uImage and uInitrd (the kernel files vmlinuz-6.11.6-kirkwood-tld-1 and initrd.img-6.11.6-kirkwood-tld-1 were generated by dpkg in Step 3):
cd /boot
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-6.11.6-kirkwood-tld-1 -d vmlinuz-6.11.6-kirkwood-tld-1 uImage
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs-6.11.6-kirkwood-tld-1 -d initrd.img-6.11.6-kirkwood-tld-1 uInitrd

4b. Boot with DTB file embedded in the kernel image.Again, this step 4b is for stock U-Boot only.

Please replace kirkwood-goflexnet.dtb below with the correct DTB name for your box (find in /boot/dts).

Generate the uImage and uInitrd (the kernel files vmlinuz-6.11.6-kirkwood-tld-1 and initrd.img-6.11.6-kirkwood-tld-1 were generated by dpkg in Step 3):
cd /boot
mv uImage uImage.orig
mv uInitrd uInitrd.orig
cp -a zImage-6.11.6-kirkwood-tld-1 zImage.fdt
cat dts/kirkwood-goflexnet.dtb >> zImage.fdt
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-6.11.6-kirkwood-tld-1 -d zImage.fdt uImage
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs-6.11.6-kirkwood-tld-1 -d initrd.img-6.11.6-kirkwood-tld-1 uInitrd

cd  /boot
cp -a uImage.orig uImage
