Hi all,

Juste a question about to upload the u-boot or firmware on device wr703n. I shoud use the RAM address 0x81000000 or 0x80800000 ?
What is the difference / effect between these two addresses?

Best regards,
Xavier

could you show me how to enter this u-boot mode.
thanks!

Hi,

Anybody have an idea about this two RAM addresses?

Bye
Xavier

I use a Serial console USB tty.
baudrate 112500
default 8N1

Is it possible to modify the code so that if reset or qss button is pressed then the router would boot normally? I have a garage door monitoring build and I used these 2 switches to monitor that if any of the two doors are open. Normally when the doors are closed the buttons are pressed. So when my router reboots(electricity is cut) then it would not boot to normally openwrt. Thanks!

pepe2k, Router TP-LINK TL-WDR4300(rev.1.3 - router, rev.1.0 - motherboards, ram - Hynix H5PS5162GFA Y5C)  -> mod Macronix MX25L128 (16 MB) + 720/480/240 Mhz U-boot pepe2k 1.1.4 - tested! safemode -> memtester 116m 50 - Ok!

Hi,

Do you have a pre-built image for tplink wdr4300?

Thanks

Also does this uboot-mod support wdr4300 v1.7?

I've changet the u-boot of my WR703N router with a precompiled image 'uboot_for_tl-wr703n.bin' from June 2013 (I couldn't find any more recent one) and I've read in the documentation about the network console mode. Is this mode present in the last year binary or is it newer than that?

I've followed the documentation and kept the reset pressed for more than 7 seconds but I cannot connect to it with 'nc -u -p 6666 192.168.1.1 6666'
The u-boot web server works fine. I haven't tried the serial console yet.

Have you stress tested it?
For the router to be stable enough with the overclock a lot of testing is required.
Based on my unit testing, my CPU can only go up to 700MHZ while RAM is good at 500MHZ
I think my Router has a lously CPU.

Look here: https://forum.openwrt.org/viewtopic.php?pid=238706#p238706, or compile your own.

It is. Be sure to set your computer's IP to static 192.168.1.2.

sakatgg  Hello.
Did you ask for U-boot or full fulfles on Router TP-LINK TL-3600 (16 MB) + 720/480/240 Mhz U-boot pepe2k 1.1.4 - tested or faster.
800/500/250 Mhz
Thank you.

Hi,

Do you any new informations?

It works, you can fix a STATIC IP and disable the firewall on your PC.

Best regards,
Xavier

Hi, Tested 780/480/240, safemode -> memtester 116m 50 -> passed over 15h 16m - very good. Test FTP (vsftpd), distilled in Filezilla video 37Gb with the laptop (WiFi-Intel Centrino Advanced-N 6235) on the mounted to the TL-WDR4300 Seagate (1GB, Backup plus, Usb 3.0) and back, then compared the md5 - coincided, not screw falls off. Details of the tests and the screens (the first 2 - LAN, second 2 - WiFi (5.0)) are here 780/480/240, 720/480/240

Hi, Do not quite understand the translation,  Go collect Fullflash, Go post U-boot pepe2k with small acceleration (CPU-600,DDR-480,AHB-240)

Please, post an official issue on my GitHub repository... I'm not able to track forum and GitHub at the same time.

I successfully build and flash my wdr3600 with this mod. But i want to overclock to 700mhz level. Which lines i need to change. I searched thread but i'm not able to find a clear answer. Any guidelines or any body help?

Thanx

Hi,

Ok I do that.
It's the first time, I don't kown if I have correct do.

BR,
Xavier

Can you share the NAT throughput performance at 780MHZ?
I want to find out if there is a significant impact of frequency and throughput.

I do not have an external high-speed Internet, the tests only on the local network. And how is it measured without the Internet?

Connect two computers ( one to wan , other to lan ) both using gigabit internet. Setup the ip address in each computer to match router ranges and test ( transfer files between them or use iperf ).

New release is available: https://github.com/pepe2k/u-boot_mod/re … 2014-11-19
Enjoy!

pepe2k, Very good, installed without a programmer, cpu and ram frequency changed in /etc/u-boot_mod/uboot_for_tp-link_tl-wdr3600-43x0.bin (photo)
zhadoom, The second computer will  free - test iperf, now only the   test Wan <-> Lan on FTP(USB Hdd mount for router) 800/500/250, Read FTP - 21 Mb/s, Save - 22,7 Mb/s

New release is working on MR3040v2.4 with 16MB W25Q flash chip. Tested on web mode and net console, but not serial port yet, I need headers to solder in. Pepe2k, what size right angle headers did you use on your mr3040 (I can see in picture on your website), and do they fit with the cover on? Thanks pepe2k

iperf WAN <-> LAN на 800/500/250

I see an iperf test between the ips 10.10.10.10 and 10.10.10.11 . How could this use nat since the server and client are in the same subnet ?

Computer user-2 10.10.10.11  <-Wan-> TL-WDR4300 10.10.10.10 -NAT- 192.168.1.1 <-Lan-> Computer user-1 192.168.1.192
1 test. 192.168.1.192 - server 10.10.10.11 - client
2 test. 192.168.1.192 - client  10.10.10.11 - server 
Screens are synchronized on both computers. What am I wrong?
Not the right team or in the wrong place run?
P.S. By the way when tested iperf Lan <-> Lan speed was 111 Mbytes / s

2 test - the same conditions as in example - 192.168.1.192 - client , 10.10.10.11 - server

Hello:
    I am trying to compile u-boot from source code, but i got an error:

./vendors/makefsdatac: line 71: java: command not found
In file included from fs.c:54:0:
fsdata.c:333:1: error: expected expression before ',' token
, 0 };
^
make[2]: *** [fs.o] Error 1
make[1]: *** [httpd/libhttpd.a] Error 2
make: *** [tplink_wr703n] Error 2

the same error appears when i change to Openwrt toolchain.
would you please help me how to solve this issus?

How about installing java?

I flashed latest binaries from pepe2k with some overclock (hexedit). But i got some memory errors. I need to pay attention because i dont have any jtag or programmer experience.

720/480/240 flashed succesfully and run memtester it's fails on some tests. Then lowered memory clocks.
720/400/200 ran memtester it's passed on each test and stable.

I want to go higher frequencies. Can i run 780mhz cpu with 400/200 memory clock? Does memory clocks limit cpu or linked?
Any suggestions about clock combinations with hex values?

IIRC the stock frequency is 560/480/240.
Does your Router pass memtester at Stock settings?
