Supporting ZSUN Wifi Card Reader (16MB Flash, 64MB RAM, AR9331)

dirlede · December 6, 2017, 8:29am

we need to get it upstream. It's not included even in the snapshot released.

The biggest problem is still that it's a wifi only device and lede ships with wifi-off as default. So it would be nicely softbricked after successfull flashing

The image available is 17.01.1 and already outdated. Some needs to get the available patches (device is full compatible with lede & has a reset routine when using micro-sd trigger when booting) and it needs to be solved that somehow wifi is accessible in these builds by default.

EDIT: I just gave a look in the custom imagebuilder from openwrt. It uses the ar71xx-generic profile and included the available patches for zsun. Maybe someone is skilled to do this for LEDE (17.01.4/snapshot) and provide a the custom/unofficial imagebuilder

Thanks for the reply-good point, i never thought of the unit would be inaccessible if the wifi was switched off on first reboot after the flash!
I'd still like to know how the posters on here built there custom builds-and with wifi enabled -as there are some packages on the current build I dont need-and some I would like to add. And I'd like to be able to have a go at actually making a build

I live in hope, even if it is 17.01.1-but looks like the community is against builds with wifi on, out of the box.....

Cheers
cabs

@rabarbara9 provided the latest (17.01.1) LEDE builds as binaries. There is no image builder included in the provided download package but a zsun-patch (0001-Zsun.patch, 12kb).

I guess someone how is skilled can port this to the most recent version (17.01.4 & maybe snapshot) and provide a custom image builder for our so beloved ZSUN!

This tiny hardware is quite powerful and with 16mb flash there could be a lot's of things included (travelmate, adblock with ssl support and far more!)

Here is the 0001-Zsun.patch

Most of this part is now beyond me, so it looks like I will continue to use the image that was kindly supplied higher up in this thread.But I will continue to be subsrcribed, in the hope the Zsun (it packs a very powerful punch for such a small device!) makes it into the mainline

thanks!

dirlede · December 6, 2017, 5:16pm

Maybe somebody is capable of porting this one to LEDE:
https://github.com/openwrt/openwrt/pull/312

macromorgan · December 13, 2017, 8:45pm

I tried making my own firmware and apparently it didn't work...

Anyone know the easiest way to debrick one of these? Also on that front, has there been progress in updating the Uboot loader with some sort of failsafe (like USB firmware loading a la the custom A5V11 Uboot)?

takimata · December 13, 2017, 10:06pm

I don't think there's an "easy" way. The device has UART and ethernet on tiny solder pads -- doable, but hard if you're not somewhat adept at soldering. After connecting a serial line and an ethernet port you can flash a new image from uboot.

macromorgan · December 13, 2017, 10:43pm

Do I need both, or can I just use either serial or Ethernet?

takimata · December 13, 2017, 11:15pm

You need both because the factory u-boot does not allow upload through serial, tftp via ethernet is the only way. There's the theoretical option of installing a more capable u-boot that will allow serial upload, but as far as I can tell noone has created one.

Edit: It seems to be possible to upload through uboot, albeit really slowly: https://github.com/maurerr/ubootwrite

maurer · December 14, 2017, 6:56am

i was just about to recommend the same thing as i'm the author of the fork
make sure you use a minimal bin image ( you can use mine https://www.dropbox.com/s/rg7d2iz4i4do30u/openwrt-ar71xx-generic-zsun-sdreader-min270416.bin?dl=1 ) as it writes with about <1KB/s so it takes at least 30-40 min

in the meantime i'll try to port the patch to latest LEDE 17.01.4 and share the code + sdk

LE: I have compiled LEDE 17.01.4 !
I've tested it and it's working - at least with upgrade from 15.05
https://mega.nz/#!R9pBxJCI!m4qA84DytH_zwexZjTJCUuQMRDLMzeSI2SUJ-QXn5i4

the SDK is:
https://mega.nz/#!81wh3BzA!wRtQrE-_mjlaPKDa49MWL9dDSrWW2ETFzs14wcsUznw

and the imagebuilder:
https://mega.nz/#!kho31TAB!Myp2u5EETPdewbDW4SZwuokE6QxBTluganp6hPEXNbg

dirlede · December 16, 2017, 3:38pm

Wow!

@maurer: Can you tell if this build (and the imagebuilder) has the two most important features for our (then unbrickable!) ZSUN included:

It starts with WIFI on (and open?) automatically when flashed without keepings settings ("stock" settings)
The micro sd card slot can trigger a reset (which will end one line up = WIFI on)

maurer · December 16, 2017, 7:25pm

yeah, it has both features as were implemented in the patch above.
it doesn't have thou dmesg kernel debug as it won't fit

macromorgan · December 17, 2017, 6:43am

I might have to get another one now then (I bricked my other one and suck at soldering on pads that freaking small.

maurer · December 17, 2017, 10:19am

You don't need soldering. Just buy this kind of probes https://m.ebay.com/itm/10Pcs-Test-Clip-Mini-Grabber-SMD-IC-Hook-Probe-Jumper-Practical/401074805909 and clip it on the 3 pins (rx TX gnd)

RangerZ · December 17, 2017, 10:23pm

For the dumb Windows user in the room, can someone spell this out for me please?

As I read @maurer's post above I think there are 2 options (files) in the post, and the files are massively different in size
1 - "minimal bin image"
2 - "Compiled LEDE 17.01.4"

Can the ubootwrite be used to load either? Are there detailed instructions for using this?

Is it easier\safer to use the original process to install 15.05 and then do a sysupgrade?

You misunderstood. One, the smaller file at around ~16 MB, is the LEDE image that goes on the device itself. You could utilize the original update process, inserting it into a factory update archive, but it's probably easier to use the one provided on that page (for OpenWrt CC) and in a second step sysupgrade to the new LEDE image.

The other one, weighing in at ~220 MB, is the matching Image Generator / Image Builder archive. This can be used to build your own custom LEDE image. It's really a courtesy of @maurer to provide this, too, since it makes it so much easier to create customized images. But if you just want to install LEDE and go from there, you'll have no use for it.

actually the minimal build image is the one in Dropbox and only 2.5mb

Not clear what you mean by "inserting it into a factory update archive". I am familiar with the page. Are you suggesting I sub the "Compiled LEDE 17.01.4" file for the SD100-openwrt.tar.gz.

What about the ubootwrite tools?

Oh, THAT one. That is a special image to use with the ubootwrite tools. Since ubootwrite writes so slow, a regular fully featured image would take multiple hours to transmit. You can use the minimal image to get the device running, and then sysupgrade to a regular image.

And how would one use this tool (ie commands at a syntax level)?

I don't know what you mean by "commands at a syntax level", but there's instructions on the Github page. I never actually tried running python on Windows, though.
