Help on getting u-boot replacement on stock Buffalo LS-WVL
September 05, 2016 12:58AM
Hi All,

I have managed to get serial working on my buffalo LS-WVL and here attached is the stock u-boot log. Is there a replacement u-boot that I can try with this device?

Try UART booting with the NSA325 u-boot:

Quote

Last Updated 19 June 2016

I've uploaded 2016.05-tld-1 U-Boot images for Pogo E02, GoFlexNet, GoFlex Home, Dockstar, Pogo V4/Mobile, iConnect, Netgear Stora, Sheevaplug, NSA320, NSA325, NSA310S/320S, NSA310, and HP-T5325.

Important Note: If possible, try to test this boot image with UART booting before flashing to NAND. See davygravy's UART booting using kwboot instruction here in this thread. The latest u-boot image released here should be used for UART booting, if your box is the type that supports it (these do not: Dockstar, Pogo E02, iConnect).

To download ARM kwboot binary for UART booting at Dropbox:
kwboot

The box is close enough to get it boot with kwboot. However, to build new working u-boot, you will need to get the GPL source from Buffalo manufacturer. And other info such as network chip (proably you can find them at NAS central) ... And post an entire stock serial bootlog if you have one.

I might be able to roll a new u-boot or not, depending on how different the Buffallo LS-WVL from the Zyxel NSA325, and the availability of GPL source.

The Buffallo LS-XL is in mainline u-boot. But it is a different SoC! so probably not close.

just tried kwboot with NSA325 uboot (without USB or hdd), it seems to boot with the attached log. If I want I can break into the NSA325 uboot to get the prompt.

What should I try next?

Looks very similar to the NSA325.

Try kwboot with the NSA325 u-boot image again, and with a USB drive and an HDD plugged in. Interrupt u-boot at count down and

usb start
ide reset
and
ping <your router IP address>

Please post serial console log for this.

Also find out which Ethernet chip this box has. It seems this chip it is different from one in the NSA325.

It's a good sign. Meaning the ethernet chip is probably the same one (you need to find out for sure). But, of course, GPIOs are different. So that info must be extracted either from the stock u-boot, or from the reference manual (none available).

Now you know that this NSA325 u-boot can be used for rescue purpose, and also serve as a baseline to build new u-boot.

When I'm done with other things (e.g. Cisco ON100 u-boot) in this forum, this u-boot could be the next one. But right now, I really don't have time to start this yet.

The ethernet chip is 88e1318-nnb2. I saw the marking on the chip so this must be it. The only thing left is to work out the GPIO then?

Hi I know it has been a long time since you r post, but how did you get the serial to work on your ls-wvl. My LS-WVL doesnt boot anymore and I cannot see why.

regards,
Andreas

It's usually pretty difficult to get the serial console working on these devices. I'd also be interested in knowing how to do so on this particular device, a brief search didn't turn up anything for me either.

That said, you can usually recover these device without console output as long as you didn't try flashing the bootloader (or lose power when the firmware updater was flashing it).

Here's a link for recovering the stock firmware:
