Does this mean that openWrt is now working on this device?

How is it flashed?

With the original software, when you get a telnet console, is there something like dmesg?

For details, please see the wiki, but i didn't find an easy way to flash it.
As i wrote in the WIKI, i use the MPR-A1 firmware to burn the hlk-rm04.

@jkent find some more AT commands, can hlk-rm04 be upgrade to openwrt without soldering out the flash now? I'm not sure about this.

This patch is based on Squonk42's MPR-A1 patch, i change the name from MPR-A1 to HLK-RM04, also the initialize way of several gpio so that we can use UART2 with Openwrt.

In theory, flashing should be possible using /dev/mtdX from telnet.  I have not had the opportunity to test this yet.  gabriel.klein already posted the mtd layout for the stock firmware.

Also untested, there is a engineering update page on the httpd that would be even easier: http://192.168.16.254/adm/hlk_update_ww … ch_com.asp

Another tip.

You can install TFTP
On Ubuntu http://www.cyberciti.biz/faq/install-co … ian-howto/

Then you can get a file on the ralink using
tftp -g 192.168.16.100 -r essai.txt

Usefull if you want to transfer some executables... like mtd_read .

Good news:
I find the memory configuartion pins.  See wiki
I also create the new DTS format patch for the latest trunk.

Bad news:
For the latest trunk i can't make the uart full (the second uart, openwrt console use uart lite) work, it seems there is a serial bug. Also for this reason i can't publish my patch. Does anyone have idea about how to fix it? See Ticket 13590 .

HLK-RM04 now (?) on DX @$16.20:

http://dx.com/p/rt5350f-serial-port-eth … ver-239155

http://dx.com/p/hi-link-hlk-rm04-serial … ack-214540

And here's HiLink Aliexpress shop: http://www.aliexpress.com/store/211069 , where they have bunch of stuff, but with expensive shipping or in multiples. They have discounts from time to time tho.

And this sellers has few of different RT5350 boards with more decent shipping: http://www.aliexpress.com/item/RT5350-m … 69619.html (this one called "AP-902M-A" they say).

Any word on whether any of these can be flashed with openWrt without unsoldering the flash chip?

You can try to ask to the seller 'hlktech' on skype a good price.
He is quite nice!

Hello everybody,
if anybody succeed with dumping original HKL-RM04 flash, i'll be appreciate if you upload it here in bin format.
I flashed the device with OWRT and now could not revert back.

Thanks in advance

@Kabron: I can probably help. Just need to know how I can dump it smile Probably something with mtd.

Do you have access to uBoot?

Especially this command.
   2: Load system code then write to Flash via TFTP.

@all
Do you have a compiled version I can upload using uBoot or some tips?
Mine is not working sad

I tried to compile OpenWRT with success... but it stops after a few seconds.

Hi, Gabriel
I mean to read flash with programmer. I successfuly did it with TL866A from autoelectric.cn. And I plan to write flash back in the same manner. You do not need to desolder the chip, read works fine.   
I do have modified uboot with programming features, but the native firmware from HI LINK is packed in unknown manner. From the other side OWRT FW is totally unusable due to very slow operation(Luci&16MB RAM?) and the chip became very hot. Trying to build OWRT on the basis of carambola tutorial I spent 2 hours on pure compilation, so time to polish OWRT for proper operation is unpredictable.
IMHO, better  to use working native FW.

How to dump the firmware content

Tip: Do it before trying to change the firmware!!

------------------------

# First enable telnet access and telnet to your device.
Check: https://gist.github.com/jkent/5748249

# On your device
# Make some space, mount a ram device on the web server, dump mtd0
killall -9 syslogd; killall -9 udhcpd; killall -9 klogd; killall -9 getty; killall -9 udhcpc;
killall -9 wscd; killall -9 ser2net;
killall -9 nvram_daemon; killall -9 dnsmasq;
mount -t ramfs -o size=4G ramfs /etc_ro/web/graphics
cat /dev/mtd0 > /etc_ro/web/graphics/mtd0.jpg

# Locally, on your linux
wget --user=admin --password='admin' http://192.168.16.254/graphics/mtd0.jpg
mv mtd0.jpg mtd0

And you are done.
You can do the same with mtd1, mtd2, etc..

mtd0: 00400000 00010000 "ALL"
mtd1: 00030000 00010000 "Bootloader"
mtd2: 00010000 00010000 "Config"
mtd3: 00010000 00010000 "Factory"
mtd4: 000c1295 00010000 "Kernel"
mtd5: 002eed6b 00010000 "RootFS"
mtd6: 003b0000 00010000 "Kernel_RootFS"

------------------------

Now you can install the new uboot (with some more actions).
https://github.com/JiapengLi/OpenWrt-HiLink-HLK-RM04 => uboot128.img

Note: Using uboot, you can flash mtd6 if you want to have the default firmware of Hi-Link.

My Firmware is

What is your firmware?

To extract the content of the directory. (Using Ubuntu...)

Install the software from
http://www.binaryanalysis.org/en/content/show/download
and install binwalk:
apt-get install binwalk

Note: you can *probably* do it with mtd0 as it contains everything!

Install binwalk and analyse mtd6 that was previously extracted.
binwalk mtd6

You see something like
791189        0xC1295       Squashfs filesystem, little endian, non-standard signature,  version 3.0, size: 2449471 bytes, 563 inodes, blocksize: 65536 bytes, created: Mon Apr  1 16:09:18 2013

Extract the squashfs image (filesystem image)
dd if=DIR-320A1_FW121WWb03.bin bs=1 skip=721024 count=2960636 of=fs.squashfs

And run
sudo bat-unsquashfs-ralink data.squashfs

You should have now the file system of your ralink/HLK-RM02 device in a local folder.


Next step: Modify and repackage the file system.

1)
Any idea how I can write back the file system in mtd6 smile (ie: How I can build uImage using modified file system.)

2)
What is the Ralink SDK version they use for this firmware?

Do you have access to uBoot?

Especially this command.
   2: Load system code then write to Flash via TFTP.

@all
Do you have a compiled version I can upload using uBoot or some tips?
Mine is not working sad

I tried to compile OpenWRT with success... but it stops after a few seconds.

My goal is to build application on top of this really nice device (And some ardumio). I need to be able to build my own firmware. smile

Hi, Gabriel
I mean to read flash with programmer. I successfuly did it with TL866A from autoelectric.cn. And I plan to write flash back in the same manner. You do not need to desolder the chip, read works fine.   
I do have modified uboot with programming features, but the native firmware from HI LINK is packed in unknown manner. From the other side OWRT FW is totally unusable due to very slow operation(Luci&16MB RAM?) and the chip became very hot. Trying to build OWRT on the basis of carambola tutorial I spent 2 hours on pure compilation, so time to polish OWRT for proper operation is unpredictable.
IMHO, better  to use working native FW.

This boot failure is concerned about memory configure, i must say this is a hardware bug of HLK-RM04, by default HLK-RM04 use 16MB SDRAM, but the memory configure select is 32MB, so Openwrt Linux kernel can't detect the memory automatically. to solve this there is two ways:
1. Modify the memory configuration resistor to fit your SDRAM size. See wiki memory configuration
2. Force Openwrt firmware to use 16MB SDRAM, add these lines to the dts file. reference: https://github.com/JiapengLi/OpenWrt-Hi … rm04.patch

    memory@0 {
        reg = <0x0 0x1000000>;
    };

Some more info.

The SDK they use is Ralink SDK 4.0.1.0
The driver is RT2860V2_ap

Apology if this is not the right place to ask this question

I am using HLK-RM04 in Serial Net mode as TCP Server
So in browser I enter Request eg (192.168.1.99:8081) which connects -> Router->Wifi->RM04 -> Serial -> Arduino. i.e. RM-04 is connected on one side via WiFi to my router and the other to Arduino using serial pins

Arduino Code basically waits for serial data terminated with blank line (http request). Once is received it sends HTTP 200 OK response to RM-04 followed by web page to be displayed on client

Problem I have
•   Chrome show OK web screen send back  from Arduino but cursor is ‘hourglass/waiting’. Chrome on Android Mobile same
•  Internet explorer do not display web page, it just waits…

I suspect the problem is with incorrectly formatted http 200 OK packet send back from Arduino or incorrectly formatted subsequent web page. Any suggestions would be appreciated

Debug info:
Request Received by Arduino on serial from HLK-RM04
GET / HTTP/1.1

Response I send from Arduino via serial to HLK-rm04
HTTP/1.1 200 OK
Content-Type: text/html
Connection: close
<<blank line>>
<form METHOD=get>
Lets go...<br />
Hello: <br />
</form>

In Chrome I get this http web screen, in IE nothing
Lets go...
Hello:

i dont use the line "Connection: close".
instead, i use "Content-Length: xxxx".

here is a sample test i did before. black box with antenna has hlk wifi module.
http://www.youtube.com/watch?v=O3aQIKMA6Nk

Thanks a lot elaber, works OK
BTW I found that closing the connection ensure that if multiple clients connect then each gets own response . otherwise responses for all clients got to 1st connected client

for anyone else benefit here is http OK & form sample code
>>>
void sendOK (){
  Serial.println("HTTP/1.1 200 OK");
  Serial.println("Content-Type: text/html");
  //on HLF-RM04 better to close connection so that each client gets its own response
  //otherwise if Conn not closed then response to Client2 will actually be send to 1st unclosed connection to Client1 (try it by connecting from say Chrome and IE to IP running HLK-RM04 server)
  Serial.println("Connection: close");    // the connection will be closed after sending back the response to client
  //Serial.println("Refresh: 5");            // This works OK, refresh the page automatically every 5 sec
   
  String sr = "";
  sr = "<form METHOD=get>";
  sr += "Lets go...";
  sr += "<br />";   
  sr += "Command : "; 
  sr += "<input type=text name=cmd maxlength=4 size=2 value=21> nnnn";
  sr += "<br />"; 
  sr += "<input type=\"submit\" value=\"ok\">";
  sr += "<br />"; 
  sr += "</form>";
  Serial.print("Content-Length: ");    //need this otherwise Chrome shows page but Cursor 'wait', IE just 'wait'
  Serial.print(sr.length());           

  //need 2x blank lines before html; 2x blank line works ok, 1x shows wait cursor
  Serial.println("\r\n");
  Serial.println("\r\n");

  Serial.print (sr);
}

hi elaber
I also wanted to say that your projects looks really cool

Hello

I am new here and I am very excited about this forum since I hve been usingthis device for quite a while already.
Please excuse if this question looks too basic but while I used the device quite a lot before I have not yet worked with its software at all.
My understanding is that all the AT-commands I send via this device are interpreted in the software. When I use for example ATZ I get back the software version E.L.M. 1.5.
Is there a way for me to read out this software (ideally with XP or windows) - then change it?

I have a device which uses this HLK-RM04 and I can upload a new firmware using its webinterface.

So basically all I like to get started with is to download the firmware - "look at it" and change it and then write it back.

Is that possible somehow with XP or windows?
Many thanks for your help!

Dear JudeWalli, do you have some software skills?

What I suggest is to find the Ralink SDK (4.x), and try to compile this SDK.

You might use the one from OpenWRT, but my experience was that it's too slow and almost impossible to use sadely.

I'm trying make this module work, but I have the same problem as mentioned above. The kernel boots but stops after:
[    0.000000] Early memory node ranges                                                                                       
[    0.000000]   node   0: [mem 0x00000000-0x01ffffff]

I compiled openwrt today as described at https://github.com/JiapengLi/OpenWrt-HiLink-HLK-RM04 so the patch for 16M ram should be active.

Any ideas?

Can you list some more detailed information(Full log info)?  How do you compile? How do you install? And the Uboot, did yo ever replace the Uboot?
