NSA320 u-boot installation problem 1
June 27, 2018 04:31PM
I'm trying to update a couple of NSA320 servers and find that the "environlent" files give me errors when it try to un-tar them.
Are the default environment (without specific entries ethaddr etc.) available in the u-boot image that can be modified and then saved via serial command??

NSA320 u-boot installation problem
June 28, 2018 10:47AM
I'm trying to updatemy NSA320's to this latest u-boot.
I have flashed the uboot image BUT i cannot find a environment file to flash.
The best (?) choice would be "uboot.2016.05-tld1" but I get this when I try to ubtar it.

/tmp# tar -xf uboot.2016.05-tld-1.environment.bodhi.tar
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors

Is there a way to get a environment.image that works with uboot 2017.07???

herb,

uboot.2016.05-tld-1.environment.bodhi.tar Is the latest u-boot env image. It should work fine.

Is there some mismatch with tar on my NSA320 or tar on my laptop running Linux Mint Mate 18.3???

All Linux system tar works the same way. Redownload the tarball and try again.

Thanks Bodhi.
It seems I did an update on my laptop and now the latest Firefox (60) does not do things like the previous one did.
I'm going to have to be careful because I have a number of files that DO NOT match their MD5sums!

Bodhi, I got my NSA320 uboot updated but I think i did not do something quite right.
I left my rootfs unchanged except for labelling my sda1 as rootfs.
There are 3 partitions on this drive as follows:
sda1 for boot and rootfs
sda2 swap
sda3 is just a filesystem for backups

When I boot from this drive I get a kernel panic.

Is there something I did that caused this? Any suggestions?

Yes. The rootfs you have created or reused has the DTB embedded inside uImage. That has intefered with the DTB loaded by the new u-boot.

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

- Generate the uImage and uInitrd (the kernel files vmlinuz-4.17.2-kirkwood-tld-1 and initramfs-4.17.2-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-4.17.2-kirkwood-tld-1 -d vmlinuz-4.17.2-kirkwood-tld-1 uImage
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs-4.17.2-kirkwood-tld-1 -d initrd.img-4.17.2-kirkwood-tld-1 uInitrd

- Set U-Boot envs for booting. The u-boot envs below are for 1st time upgrading, you don't need to do this step if you've installed the latest U-Boot for Kirkwood. Or you are upgrading from my previous released kernel. Just make sure the DTB file is the correct one for your box, replace kirkwood-goflexnet.dtb below with the correct DTB name for your box.

fw_setenv load_dtb 'ext2load usb 0:1 0x1c00000 /boot/dts/kirkwood-goflexnet.dtb'
fw_setenv load_initrd 'ext2load usb 0:1 0x1100000 /boot/uInitrd'
fw_setenv load_uimage 'ext2load usb 0:1 0x800000 /boot/uImage'
fw_setenv usb_boot 'run load_dtb; run load_uimage; if run load_initrd; then bootm 0x800000 0x1100000 0x1c00000; else bootm 0x800000 - 0x1c00000; fi'


4b. Boot with DTB file embedded in the kernel image (no U-Boot envs changes are needed if your system already booting on USB or HDD)

Again, please replace kirkwood-goflexnet.dtb below with the correct DTB name for your box.

Generate the uImage and uInitrd (the kernel files vmlinuz-4.17.2-kirkwood-tld-1 and initramfs-4.17.2-kirkwood-tld-1 were generated by dpkg in Step 3):
cd /boot
mv uImage uImage.orig
cp -a zImage-4.17.2-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-4.17.2-kirkwood-tld-1 -d zImage.fdt uImage
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs-4.17.2-kirkwood-tld-1 -d initrd.img-4.17.2-kirkwood-tld-1 uInitrd

So you need to reverse that 4b step by restoring the original uImage: 
cp -a uImage.orig uImage

Usually by mouting this drive on another Linux box. But since you have serial console, you could do this to avoid having to take the HDD out:

Power up, interrupt serial console and clear this env temporarily. 

setenv dtb_file
boot
After it booted into Debian, 

cd /boot
cp -a uImage.orig uImage
sync
and reboot.
