Topic: 7Links 6in1 Multi-WLAN Router ( PE-8074 ) / Processor Star STR9105

The content of this topic has been archived between 19 Mar 2018 and 22 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hello,

I have just disassembled the above device to look what kind of hardware this little thing provides.
It is sold in Germany by a company called "Pearl".
http://www.pearl.de/p/PE8074-7Links-6in … 4Mbit.html

The device is very small in size and already contains the switching power supply as a separate PCB.
The other PCB is the CPU board which hosts a Mini-PCI WLAN card with a Ralink 25xx chipset.
The CPU itself is a STR9105 with ARM922 core.
http://www.starsemi.com.tw/vChn/Prods/str9105.php
Flash memory is from Macronix (29lv640). DDR memory is from Nanya.
The CPU board contains a 20-pin standard ARM JTAG header. So far, I did not find out if there is a serial console, too.

Also, I did not find out which operating system the device is using. The CPU manufacturer Star provides support for Nucleus and Linux.
At the moment there are no firmware updates available, so no images to analyze.

The CPU board is named "Navi R120G" Rev3.0.

The webpage from Star also states that other members of the STR91xx family are used for Linksys devices like the WAP4400N or the WRVS4400N.

Looking on the Linksys webpage, I find:
ftp://ftp.linksys.com/opensourcecode/wa … v1.0.3.tgz
ftp://ftp.linksys.com/opensourcecode/wa … 1.2.11.tgz
ftp://ftp.linksys.com/opensourcecode/wa … 2.8.tar.gz

Those GPL source code packages contain the necessary kernel patches for the STR91xx family.

I am writing all this just for reference purposes. I searched the web for information about this device in particular, but I did not find very much. ;-)

Best regards!

Hello,
Concerning the serial console: Behind the usb connector is a 4 pin connector. TXD seems to be the pin close to the edge of the board, GND the opposite one. During boot time a connected scope shows some activity. I have not found further info about the device yet.

Hello,

I have just find some information at the sapido homepage
http://www.sapido.com.tw/EN/we1100-o.htm

I think the WE-1100, WE-1110 and WE-1200 use the same HW, but just different firmware-versions...


Best regards!

What does it mean to the WRVS4400N? Can we run OpenWRT on it? I bought a WRVS4400N and have many problems. If somebody really wants to work on it and needs a WRVS4400N device, maybe he can take my one.

Hi,
     That unit is manufactured by Amigo Technology and they have firmware you can examine on their website.  http://www.amigo.com.tw/3R121g.htm
     I have a unit but the brand name is Sapido. I am sorry to see that it does not support WPA2.  It might be a limitation of the RT2561T chipset, but I am not sure.
     I read a review on a German website which says the wireless is very poor, so I think I will put an external antenna on it and also I will try to put a power cord on it because it does not work well to plug it directly into the the outlet.
     Have you tried to look at the serial console? Does it work? Is it Linux?
     I notice that when I telnet to it, I get a prompt which looks like this: "pek>" and I don't know what to do with that. Do you?

The same device is sold by Solwise as the 3GWIFIMRW at http://www.solwise.co.uk/3g-routers.htm

I downloaded the firmware from http://www.amigo.com.tw/Download_Center.htm.  File is called FNBENE3R121G2004-1.rar.

Unrared this to get a file called VER2.0.4 with size 5,649,268 bytes.

Used a binary editor to inspect it.  Found the standard gzip header pattern x1F x8B x08 at offset 0x31F0.  Chopped the file at this point and used gunzip.  This produced a linux kernel with size 2,297,212 bytes.

Back to Ver2.0.4 and look for the next gzip header.  Found x1F x8B x08 at offset xF2590.  The zipped file is called ramdisk.  Chopped again and unzipped to get a ramdisk file with size 18,227,200 bytes.

Scanned the ramdisk with binary editor for the telnet prompt "pek>".  Found it at offset xC4340.  Surrounding it are the strings used by the telnet command interpreter.

The most interesting string is "pekpekengeng" (without the quotes of course).  Type this into the telnet prompt and suddenly the device comes alive.

After typing this magic string I can start typing regular unix commands such as ls and ps and I can see their output.

We have lift off!

how about a dmesg then?  BTW, nice hacking!

So for anyone who is unsure the process to get root access to the Solwise 3GWIFIMRW / Amigo 3R121g / Sapido WE1100 / 7links 6in1 / Star STR9105  is:

From a PC that is connected to the same network as the router use a telnet command with the address of the router (usually 192.168.1.1 or 10.64.64.64) and login with the administrator username and password (usually admin/admin):

  telnet 192.168.1.1
  Login:admin
  Password:admin

You are presented with a very limited program that displays a pek> prompt.  You break out of this program by typing the magic word pekpekengeng.

  pek>pekpekengeng
  sh: pekpekeng: command not found

Now you can start any unix program you like.  The most useful one is a shell so type sh and the root prompt # will appear:

  pek>sh
  #

You can go anywhere you like, run any program you like.  Some interesting commands are:

  # uname -a
  # dmesg
  # ps
  # ls /bin
  # ls /sbin
  # lsmod
  # ifconfig

I would like to see posts from anyone who can confirm or deny that these commands work on other brands of the same box, or maybe on other models in the same family.

What does it mean to the WRVS4400N? Can we run OpenWRT on it? I bought a WRVS4400N and have many problems. If somebody really wants to work on it and needs a WRVS4400N device, maybe he can take my one.

I just sent you a PM.

So that you don't have to open your router here is a guided tour of the Solwise 3GWIFIMRW.

I managed to open the case by sliding my thumbnail round the groove and popping open the catches one at a time.

The case slides up and open with the power supply and tiny wifi aerial in the top half and the main circuitry in the bottom:
http://img383.imageshack.us/img383/1316 … 056qc6.jpg

To separate the top and bottom take the power supply plug (red, yellow, black wires in the picture) out of its socket and gently remove the wifi lead (black wire) from its connector.  The blue wires you can see carry mains voltage into the power supply, so only young children and pets should play with these:

The wifi transmitter has its own board, with spring clips at each edge to hold it in place.  Open the spring clips and the wifi board lifts out as a separate unit:

The wifi board in detail.  There are no components on the reverse of this board.  Notice that it has two aerial connectors in the bottom left corner (the circular gold connectors).  The one at the outside corner is not used in the 3gwifimrw:
http://img179.imageshack.us/img179/6361 … 070am7.jpg

The main circuit board is held in place with two small screws.  Take them out and the board lifts out of the case.  Most of this side of the board is covered with surface mount, passive components so there isn't much to see here.  The components are covered with a protective plastic sheet so they are insulated them from the wifi board when it is installed:

Now for the fun side of the main circuit board:
http://img512.imageshack.us/img512/4628 … 075vh7.jpg

And for those of you who like your chips:
http://img209.imageshack.us/img209/1459 … 076bh3.jpg
http://img149.imageshack.us/img149/6823 … 077fl2.jpg

Now, back to the passive side of the main board and we find something interesting.  Just behind the USB sockets there is a four pin connector.  Rumor has it that this is the serial port for the machine.  Through this we can talk to the armboot software and gain complete control over how the router boots and configures itself.  And in front of the 4 pins you can see 20 solder pads in a 2x10 grid for a JTAG connector:

That's the end of the tour.  Please visit the gift shop on the way out.

Sources: ftp://ftp.pearl.de/treiber/PE8074_src.rar (92999 KB)

Unpacking the source and poking around inside we find the file config.in which starts with:

mainmenu_name 'SnapGear Embedded Linux Configuration'

So we hop over to http://www.snapgear.org and http://ftp.snapgear.org/pub/snapgear/tools/arm-linux/.  Here we find a set of tools for compiling source code in arm-linux-tools-20070808.tar.gz.  This is a chunky 270MB so you will probably only download it if you are sure you need it. The gz unpacks into /usr/local and gives you a set of tools such as arm-linux-gcc and arm-linux-gfortran for compiling different languages.

I typed in a simple hello.c:

#include <stdio.h>
void main(int argc, char **argv) {
  printf("Hello World\n");
}

It compiled into a static binary it with the commands:

$ arm-linux-gcc -Wl,-static -o hello hello.c
$ arm-linux-strip hello

I transferred it to my Solwise 3GWIFIMRW using netcat:

(On the 3GWIFIMRW) # nc -l -p 8888 > hello
(On the build machine) $ nc 192.168.1.1 < hello

Fix the permissions and execute it:

# chmod +x hello
# ./hello
Hello World

So it works.  But it is only a demo, and it has several limits:

* The hello file is only in RAM, not flash memory.  It will be lost every time the router restarts.
* Linking the program statically does not test if this compiler can work with the dynamic libraries in the router.
* The only kernel call tested by this program is write() and there are a lot of other kernel calls that need testing.

I'd be interested to see posts from anyone else who tries this compiler.

Hello,

has anybody "successfully" tried to upgrade a Perl PE-8074 or the Sapdio WE-1100 to a firmware with UMTS/3G support?

I have tried to install the other firmware and got an error message...

Version format error!


Or is there any other custom firmware, - maybe command line only?

Bye

Cyberg

Has anybody managed / looked at porting OpenWRT to this device (The Amigo 3R121g) or it's big brother (3R621g)? 

If not, I may be able to arrange a bounty to help out...


-rdj

Hi, i have also 7links, and tried to cahnge firmware but without any luck.

it has the same info..

Connection to host lost.



is thera any other way to chanfe firmware .....

has any one tried the jtag

is there possibility to change it over telnet or tftp....

Where is difference in firmware.???

any one cen provide me help ?

too bad that this topic is dead sad

Hello!

I've flashed the 7links NAS with Amigo firmware  ... it was a hard way but now it works!

At first I've corrupted my router by flashing firmware to mtdblock2 using linux-shell and "pekpekengeng"-hack ...
After this my router didn't respond to nothing anymore! No ping, no DHCP - nothing ...

I've opened my router and used a serial cable to connect to my NAS.
I've built my own cable. For reference purposes I've used this sites to built it - Thanx to the authors!

http://www.neolics.com/pdfs/dku-5.pdf
http://buffalo.nas-central.org/wiki/Use … inkstation

After this and connecting serial cable to my PC USB I could see the messages posted here:

https://forum.openwrt.org/viewtopic.php?id=22688

After some testing I found the keystroke to press: CTRL-C
Press this keystroke immediately after seeing the message: Hit any key to stop autoboot:  1

After pressing this keystroke in my terminal (I've used Putty) I've entered the ArmBoot-Console-Mode. Here you can repair the firmware using TFTPBOOT-command. At first use "printenv"-command to see all environment variables of ArmBoot. "ipaddr" is the address of your NAS and "serverip" is the IP of your TFTP-Server. Now setup your LAN-connection to the given serverip, connect a LAN-cable between the NAS and your PC and use this commands to boot another firmware:

tftpboot 0xcf00000 Ver2.0.4 > Enter
go 0xcf00000 > Enter

Now you should see all kernel messages of linux booting up ... You should know, that a reboot of your router will still boot the old firmware. With tftpboot we wrote the firmware to RAM not to flash.

I haven't found some commands in this ArmBoot-Version to permanently write the changes to flash. Because of this lack I've used the web-interface of the newly booted firmware via serial cable to write the same image again (used for tftpboot) to flash ...

That's it! For questions write into this topic ...

Ciao, ariaci - have fun!

Hi ariaci

i have question dis you use 3 pin or 4 pin cable where did you conect it and what is the pinout?

thank you

i am trying to change firmware but i can not get to ARM boot

Hi pkucan!

You need a connection to all FOUR pins to build your own serial cable. This is needed because you will need power and ground to work with some USB to serial adapters. Besides this you should add a LED like in the linked pdf to see if you've used the ciorrect pins ...

The serial port of the PE8074 is located behind the two USB connectors. You will see a small triangle in front of the first pin. This is the PWD pin. The layout is the following:

PWD - TX - RX - GND

This is taken from the PDF ... the colors of the cables of the USB to serial adapter are taken from nas-central ...

Feel free to ask other questions :-)
I think this is all you need to get a connection to ARMboot of the PE8074 ...

hi

i think i have found my problem i dont have an Original DKU5

but i have PL2303

could be this my problem?

Hi again!

My first cable used also an PL2303 chip. But I've had problems with this chip. Sometimes there was an output in Putty and sometimes not. That's why I've bought another cable. The second one is using a chip from ArkMicro. The complete USB to serial was named "ArkMicro USB to Serial" ... in the inner of this main cable you can find five or six cables (I don't know the exact number at this time because I've hidden all inner cables and can't see them anymore).

Please try another cable. I think this is the PL2303 chip causing all problems ...

Ciao

I've had no problems with the Prolific 2302 USB to serial converter. However, I did end up having to examine the serial port a bit more closely. The triangle at one end of the header denotes pin 1. From memory (IE, I could have got Tx and Rx mixed up), the pinout is as follows:

1. TxD from computer
2. N/A - could be a 3.3V supply, could be something else?
3. RxD from computer
4. GND

Your terminal program needs to be set NOT to use hardware handshaking (CTS/RTS/DTR/DSR), as this is not available. The line settings are 38400, 8 data bits and 1 stop bit. Note, this is 3.3V logic, NOT RS232, so you'll need an appropriate USB to serial converter that runs at 3.3V. The Ctrl+C handling is a little odd, but  I haven't looked into this yet.
