Thank you, saturn-b, great work. Works brilliantly. Better than chinese uboot with web-interface(well, because it just works)
Where can i see source code of this? I want to compile this uboot with different settings and for another device.

Failsafe
if the 192.168.1.1 interface does not respond, the only chances to debrick are serial or tftp firmware uploads. Both need soldering the serial cables ...
That is true. But let's fix the Failsafe mode for this device in OpenWrt. Anyone?

probono is right , this is CleanWRT uboot source based on Ralink and pepe2k web failsafe.
I just moved starting kernel address from 0x040000 to 0x050000 and fix reset switch gpio to work with NEXX WT3020. Here is the diff :

Okay, thank you for reply. Can you tell, what tools were you using? I mean, was OS 32 or 64bit, did you use crosscompile environment or just ralink sdk? Which version, if so?

I'm using ralink toolchain from Ralink SDK 4.1.1.0 just extract SDK and install it :
Install Tool Chain:
#tar xvf MTK_Ralink_ApSoC_SDK_4110_20121102.tar.bz2
#cd RT288x_SDK
#sudo cp toolchain/buildroot-gcc342.tar.bz2 /opt/
#cd /opt
#sudo tar xvf buildroot-gcc342.tar.bz2The extract procedure makes a directory equivalent to "/opt/buildroot-gdb"
Install LZMA Utility:
#cd RT288x_SDK/oolchain/lzma-4.32.7
#./configure
#make
#sudo make installYou can read for more detail in Ralink SDK manual on doc folder.
My machine is 32 bit ubuntu by the way.
You helped me a lot, thank you!

Thank you, saturn-b, great work. Works brilliantly. Better than chinese uboot with web-interface(well, because it just works)
Where can i see source code of this? I want to compile this uboot with different settings and for another device.
Are there any other major differences between this and the Chinese U-boot (see also this thread: https://forum.openwrt.org/viewtopic.php?id=55180)?
Well, major difference is that chinese uboot is some kind of universal(supports any memory size and type, any flash). This way it's very cool. But it is also a weak point.
This uboot doesn't work well, because, WELL, it doesn't properly boot some images. Some images boot okay, others - no. So, it's like a roulette. With this uboot(from saturn-b), i verified, and all firmwares i have boots properly.
But, this uboot lacks some important features, like network console or, very nice feaure, μDHCP server. At the same time friend of mine reports that he can't enter web-interface using this uboot. Don't know why.

So these features are also missing from pepe2k's U-boot? That's a shame because the Chinese one is apparently closed source.
I think i need to clarify, because in previous message was real mess.
saturn-b's uboot:
+ boot all images
+ opensource
- need to compile for exact router
- don't have μDHCP server/Network Console
chinese universal:
+ runs on any hardware
+ have μDHCP server/Network Console
- not boot all the images(i believe it's bug)
- closed source

U-Boot project is GPL licensed! If someone is closing project based on U-Boot (any kind of modification), he/she is simply violating GPL license!
My official modification doesn't include support for any other SoCs than Atheros AR933x/AR934x at this moment.
I'm sorry my folder is messed up , I have to start all over again.
Here the compressed folder tested and works.
Well i deleted my post because i already figured out what i'm doing wrong. But anyway, thanks.

very nice. is inspired by same mods for tp-links 703/3020?
if you integrate small usb2ttl inside of router, then it would be best mod 
yesterday i received the W25Q128FV chip, and i want to make a modification via arduino flasher . I have a question about firmware compatibility.
If i flash the new chip and succesfully solder it back, can i upgrade a newer firmware from here: https://downloads.openwrt.org/snapshots … ps/mt7620/
or i need to build a custom firmware which support 16MB?
tommi32
can you share link to arduino flasher?
here: http://flashrom.org/Serprog/Arduino_flasher
but i didnt try it, im newbie in this

Success! I managed to compile an image from git r43771 and flashed it over the original firmware. All of the 16MB flash are usable, with ~12MB available on / with no packages installed except Luci.

The problem with that is that nobody seems to manufacture 32MB or 64MB flash chips in SOIC-8 package - they are all in SOIC-16 or DFN/BGA, even though only 8 pins are used. It's not impossible but it's not a simple desolder/resolder project as it will require building an adapter
hi,i made a serrios mistake,
i flash the openwrt-ramips-mt7620-wt3020-16M-squashfs-factory.bin to a new chip,
and got the router run into a brick, there is nothing output on the TTL console.
this file doest not the bootloader,so it can not booted.
i must flash the wt3020originalfirmware237.bin to a new chip,
then in the web page to flash the openwrt-ramips-mt7620-wt3020-16M-squashfs-factory.bin file.
i am a newcomer, and i even don't know whether am i right about this ?
may anybody give me an confirm or get me corrected?
is there a way to flash the fireware and the bootloader together?

Is there any calibration data and/or MAC address on the chip that needs to be preserved when flashing the new chip? On Atheros-based systems, there is an "ART partition" for that.
Well if you look through the boot log it has the following snippet:
Creating 4 MTD partitions on "raspi":
0x000000000000-0x000000030000 : "Bootloader"
0x000000030000-0x000000040000 : "Config"
0x000000040000-0x000000050000 : "Factory"
0x000000050000-0x000000800000 : "Kernel"I assume that the factory partition contains calibration data. That partition is preserved when flashing, and it is also defined in the .dts that I posted. Of course, the factory partition being at the beginning of the chip makes it easy to expand to larger chips.
I have ordered and am currently awaiting delivery of some 256Mbit and 512Mbit SPI flash chips; like I said, there aren't any in 8-SOIC package, but I found some in WSON (8x6mm) package which should be solderable with a bit of luck onto a 8-SOIC pad pattern. Flashing them in my programmer is another matter though, I don't have an appropriate carrier and that may be a problem.
can anyone tell me have to get the route boot with this firmware ?
what does it mean
" flashed it over the original firmware "
????
which file should i use ?
and how shuuld i flash it?
just flash breed bootloader to beginning of flash chip. then flash full dump via breed.

i flash the wt3020originalfirmware237.bin file back,
you mean i should flash the breed-mt7620-reset1.bin file,
and in the web interface of the breed bootloader,
i should choose the
openwrt-ramips-mt7620-wt3020-16M-squashfs-factory.bin
or
openwrt-ramips-mt7620-wt3020-16M-squashfs-sysupgrade.bin
?
what is the diffirence of the two file ?
