[SOLVED][NSA325v2] Booting from USB hangs after kernel decompression

First of all I'm new to this and have a second-hand NAS, so I'm pretty sure I've missed something.

I'm booting from USB, with the 5.2.9 kernel. The boot looks like this:

NSA325> reset

Uncompressing Linux... done, booting the kernel.

And that's it. I can leave it hanging. I've tried disconnecting the USB-TTL, reconnecting, nothing is printed, but the device is there.
If I'd plug the device to the network no address

In my own troubleshooting I wanted to upgrade u-boot, but I didn't got past kwboot:

❯ kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.nsa325.mtd0.kwb
Sending boot message. Please reboot the target...-
Sending boot image...

So I'm kind of stuck here.

Yes, your installed u-boot is a bit old, so to run with the new kernel/rootfs, the envs need some adjustment (not necessary with the latest u-boot 2017.07-tld-1). And also best to add earlyprintk to bootargs for troubleshooting purpose.

Power up, interrupt serial console and

setenv bootargs_linux 'console=ttyS0,115200 mtdparts=orion_nand:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2) root=LABEL=rootfs loglevel=8 earlyprintk=serial'
setenv loadaddr 0x800000
setenv uinitrdaddr 0x02100000

and then

boot

Note that since this is older u-boot, you still need to append the DTB to uImage. As described in Step 4 during preparation for Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2. So do Step 4 if you have not done so.

Replace the kirkwood-goflexnet.dtb name below with kirkwood-nsa325.dtb

Quote

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Do not do this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time).

Please replace kirkwood-goflexnet.dtb below with the correct DTB name for your box (see the folder /media/sdb1/boot/dts for the exact spelling of your Kirkwood box name).

Generate the uImage with DTB embedded inside:
cd /media/sdb1/boot
cp -a zImage-5.2.9-kirkwood-tld-1 zImage.fdt
cat dts/kirkwood-goflexnet.dtb >> zImage.fdt
mv uImage uImage.orig
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-5.2.9-kirkwood-tld-1 -d zImage.fdt uImage
sync
