Zyxel NSA 325

Hello!

Since a few months I have been passing up this task to get OpenWRT onto the Zyxel. I followed their instructions only to find that the installed version of u-boot (1.1.4) would not recognize any flash drive, hdd or network attempt to get OpenWrt last U-boot onto it.

I tried following the instructions here but I am too overwhelmed, so sorry if I ask stupid questions. Someone told me to take a look at kwboot but I have no clue how to use it.

I tried "kwboot -t -B 115200 /dev/ttyUSB0 -b u-boot.kwb -p" but am getting an xmodem protocol error back.

If that works from that uboot version I should be able to flash uboot to nand and after that openwrt?

edit: I just tried to get into the telnet backdoor, is that of any help?

Thiefrainb0w,

See these tutorials in the Wiki thread

Rescue Systems

....
Rescue System V4, using a custom LEDE firmware (BETA)
Rescue System for Pogo E02 using LEDE/OpenWrt (Install with Serial Console)
Rescue System for Pogo V4/Mobile using OpenWrt (Install with NetConsole)


OpenWrt installation for the Zyxel NSA325 is similar to these 3 threads. Especially the Pogo E02.

Not sure why if you're trying to install OpenWrt you don't make use of the OpenWrt wiki page for the ZyXEL NSA325.

Thanks for the hints, first time flashing something that isn't an Android.

I semi followed this https://forum.doozan.com/read.php?4,100764,101409#msg-101409

Using Telnet I am now in the NSA325, got a FAT flash mounted that has openwrt u-boot.kwb and the openwrt.bin fpr nsa325 and U-boot flashing utilities unpacked in /tmp/tools

From another not to recent thread it seems openwrt u-boot already contains the needed environments https://forum.doozan.com/read.php?3,119919,119939#msg-119939

These are the first outputs and I guess it looks good to go. I should be ok with the bad blocks right?

cat /proc/mtd

mtd0: 00100000 00020000 "uboot"
mtd1: 00080000 00020000 "uboot_env"

Next step would be:

# Install U-Boot

/tmp # ./tools/flash_erase /dev/mtd0 0 4
/tmp # ./tools/nandwrite -p /dev/mtd0 u-boot.kwb


After this I could stick to the openwrt guide: (https://openwrt.org/toh/zyxel/nsa325)

./tools/fw_setenv mtdparts 'mtdparts=orion_nand:0x00c0000(uboot),0x80000(uboot_env),0x7ec0000(ubi)'
./tools/fw_setenv bootcmd 'run setenv bootargs; ubi part ubi; ubi read 0x800000 kernel; bootm 0x800000'


After that exit and reboot and hope I see a new u-boot and read from usb to flash openwrt.bin with fatload

Just gave it a shot, and I'm in new U-boot! I had to use the padding flag while using nandwrite.

This is what serial console gave out after reboot

Get the listing of the envs here, it might not have enough to allow you to read.

printenv
And post what you've tried. Basically, the entire serial console log until the error.

Got OpenWrt flashed and booting. Using fatls command mounted the device first I think and then made it readable.

From there I flashed openwrt.bin to nand, a little fighting with setenv got it to boot on its own without serial commands.

Thanks for the initial links you posted. By chance, do you know if wake on lan has to be set in u-boot? Most docs I find are more centered to sending wol packages to other hosts, but not the openwrt box itself.

Not in u-boot. For this box, WOL must be controlled using i2c command. The i2c command can be executed in Linux.


In the Wiki thread we have WOL i2c command for Zyxel NAS326. But the NSA325 WOL i2c command has not been found yet.
