OpenWrt 15.05 port for the ZSUN WiFi SD Card Reader

openwrt-zsun's Issues

Tutorial For Installing via Ubuntu

Hello,

I'm wondering what image I should download to use for zsun wifi card reader, and are there any instructions for doing it via Ubuntu computer?

Thanks

Official Kernel Modules in Repository

What is the reasoning behind the official kernel modules in the repository not working with zsun? I'm trying to get kmod-batman-adv to compile but come up with the error.
types.h:386:26: error: expected ')' before numeric constant DECLARE_EWMA(throughput, 1024, 8)

I did test with the official kernel module and had to recover via u-boot and a serial connection.

LEDE

What about new LEDE project. Any chances for port?

samba performance or issues?

The ZSUN seems underpowered for the Chaos Calmer samba package - 128 MB recommended, 64 MB available. Has anyone successful replicated the file server functionality of the original firmware? Any caveats or special configuration issues? Or is maybe ftp better suited for this?

ZSUN hardware compatibility with Wifi Pineapple Nano firmware

Hello Andrzej, guys,
The initial idea was to port hostapd-mana to openwrt and susbtitute the original hostapd within the ZSUN in order to use it also for pentesting 802.1x networks during engagements at work... sadly I got stopped due to diffing/merging issues while porting hostapd-mana to its OpenWRT version.

However, googling aroung I have figured out that one guy managed to modify the Wifi Pineapple Nano (same Atheros SoC of our ZSUN) to push it in another AP:

http://sapinski.com/2016/02/13/wifi-pineapple-firmware-for-gl-inet-gl-ar150/
https://github.com/kow/glinetpineapple

And this guy did the same:
https://github.com/smrx86/STPF2

I was wondering if you could give a look at the procedure to patch the Pineapple Nano original fw.

I was following the guide in the URL above...
build firmware-mod-kit from https://code.google.com/archive/p/firmware-mod-kit/wikis/Documentation.wiki
extract wifipineapple firmware (https://www.wifipineapple.com/nano) with firmware-mod-kit
clone https://github.com/domino-team/openwrt-cc
cp firmware-mod-kit/fmk/rootfs/* openwrt-cc/files/*
and finally, build openwrt-cc.
But instead of using openwrt-cc repo... I have tried with yours https://github.com/Emeryth/openwrt-zsun but without much success.

U-Boot mod

It's seems https://github.com/pepe2k/u-boot_mod the bootloader could be replaced in theory. I remember the Nokia N900 Smartphone can boot from sdcard/ execute scripts from sdcard. Couldn't U-Boot on the Zsun Cardreader be modified to load a boot.scr (or whatever) from sdcard for ext root or flash a recovery from a bricked flash?

Reset OpenWrt config without serial console

Is it possible?
Flashed openwrt well.
Then configured as AP Clint, AP disapper, can't see device wireless.
And it did not connect to other AP.

Wiki Guide didn't work

The https://wiki.hackerspace.pl/projects:zsun-wifi-card-reader:factory-update Guide didn't work for me because connecting to PC didn't work. I got it working with Android and put my findings in pdf. Please update the Wiki.

simplified img copy

Beautiful work gentlemen!

Just wanted to mention, too lazy to setup tftp and never getting anything but status{-2} from http://10.168.168.1:8080/goform/upFirmWare, I copied the kernel and rootfs straight to the SD via USB. Worked just fine. Thanks,

USB Gadget mode, any success?

Hi guys,

The Hackspace.pl wiki mentions USB gadget mode. I'm interested in trying it out, and was wondering if anyone has managed the steps described, which are:

Port the code
Remove the bootstrap resistor setting USB to host mode
Remove the card reader PCB and rewire the the USB signal pins

Has anyone managed this so far? If so, care to share your findings/code?

FEATURE: add recovery option using file checking on SD card

Hi.

I want to suggest a simple idea I saw here:
https://www.davidgouveia.net/2016/03/avoid-being-locked-out-of-your-zsun-wifi-reader/

The idea is to reset the device settings if a "/restore" file exists in SD card.
It's implemented using a simple init.d script.

This idea is much simpler than current method: trying to insert/remove SD card during boot to simulate a button click.

I tried this idea myself and it works nice. However, after resetting the device settings, the script itself is also deleted... This means that if I forgot to create it again, the next time, I will be stuck with inaccessible device (and have to use the less-convenient current method of SD card insertion during boot).

Adding this init.d script into the openwrt-zsun firmware code will make it much easier to ALWAYS reset the device in case of misconfiguration, without worrying if the script exists or not. It will always be there.

a bunch of questions regarding original fw

Hey guys,

I'd like to use the device as a rather boring mass-storage on a tv and control it without app (only web, smb, telnet). I'm not sure if I really need openwrt in my case and have couple of questions:

I assume the following will put it in smb mode!?
http://10.168.168.1:8080/goform/Setcardworkmode?workmode=0

Subsequently does the following put it in mass-storage mode?
http://10.168.168.1:8080/goform/Setcardworkmode?workmode=1

Is wifi / web / telnet always available, regardless of the mode?

Can you also switch modes via telnet?

Unfortunately the tv requires the storage to be whole-disk ntfs formatted. Is the smb mode automounter able to mount such a partitionless ntfs disk? If not, can I mount it via telnet?

SD Card problems

Hi,
I'm having some interesting issues with Micro-SD support. Wondering if anyone else has had the same thing or knows what's going on.

When I use a Micro-SD card I can see it on boot and mount it fine, I can even list files and directories, and I can query the usb SD controller via lsusb. When I try to access the files after a small amount of access, the USB device appears to disconnect. Here's the output of logread from doing a cat of a file on the Micro-SD:

Does anyone know what's happening? The drive and USB SD card reader are no longer visible in lsusb after this happens, so it looks like the USB SD card reader is being disconnected.

Upstreaming changes

Hi Emeryth,

Thanks for your work, I got it running on my ZSun, and it's pretty cool. Do you have any intentions to upstream your patches back to OpenWRT, so later versions of OpenWRT will run on the ZSun as well? Thanks!

Zsun keeps rebooting when WiFi is enabled.

I've hacked two devices and they seem to present the same problem. I have updated the original firmware with the SD100-openwrt.tar.gz, and without any other intervention, when the wifi gets started (while booting) it resets the whole system. This goes over and over again, endlessly.

I have the uart being soldered and if I immediately delete the /etc/config/wireless after the console gets enabled (before allowing wifi driver to read and start the wifi) everything remains stable. If I restore the file and call "wifi", the system gets rebooted.

On one of the devices, I've replaced the flash memory with different chip from an working Carambola2 module. It presents the same problem, even with a completely new uboot and firmware. Getting mad, I've looked for HW differences, and the only relevant one that I've found was the quartz, which is 25MHz on zsun and 40MHz on Carambola2. So I've replaced the zsun quartz with an 40MHz and changed the according bootstrap pin. Tada! now it's working.

I haven't tested yet with current openwrt-zsun build, but I suspect it would work.

Does anyone encountered this issue? Does anyone know what is the relation between WiFi and the input quartz?
