Ok, i connected serial cable to my ZTE device, here is boot log:

The problem is that i can't stop device booting. It looks like device does not see my keystokes. I tried to disconnect RX from board - had rubish on screen instead of booting log, so fisically all three are connected RX, TX, GND.
I tried Putty and Hyperterm as terminal - reaction the same. Serial parameters are 115200/8/N/1/N

Any ideas?

Did you try pressing both: 1, 2, 3 and space? (I suppose we need 1 or 2 ... but maybe it's usefull try the others)

Did you verified the cable? TX (from cable) - RX (from router unit) are ok ?

yes, i tried everyone, no reaction, no echoes. As i said before when i disconnected board rx then i had rubish on terminal, when connected back output is ok, so i suppose cable is ok.

bthw, my serial converter is Jennic JN-AC001 - http://datasheetz.com/data/RF%20and%20R … heetz.html

If you disconnect board RX (cable TX) you need to receive same thing -good or bad-, so something is wrong here -> review & fix connections. Your serial converter is 5v or 3.3v ? In the website you post it's not specified and you need 3.3v levels.

Are there UART levels different from 3.3v?

UART levels are aprox +11v/-11v and this board serial levels are +3.3v/0v (in example, some PIC microcontroller are +5v/0v) ... That's the reason of this checkings

+/- 11V thing is called RS232 ... UART is simply a protocol

Ok, ordered profilic based converter.

Lol ... thanks blogic,

Now you're reading and correcting people only (nothing more constructive) can you correct this ? https://dev.openwrt.org/ticket/11235

In this thread, we talk about more things than UART, in example, HTTPD is not working and by that, TFTP is broken too in U-Boot. If you compile your own u-boot with HTTPD disabled, TFTP is working. Maybe is a gcc thing, i don't know, but official u-boot is broken, if you flash it, you have no connection to router than serial.

Please correct that Now im corrected and know UART is not RS232 (maybe the people here doesn't matter that little difference when we are referring all times to computer vs router ... but, thanks anyway

Anyway now im remembering, blogic, is the opposite. UART (and modern ones is USART) are only a chip, and by that, is the +/- 11v | +5/0v | +3.3/0v thing. RS-232 is a communication standard = protocol.

@graciasSara

Does anyone have success with the EasyBox 802 (ARV752DPW)?

What do you mean ?

I have a ARV752DPW, and for now everything is working out of trunk ....

UPDATE:

Hey right now I am knowing what you mean... I have forwarded you from your previous post to this one.

So ....

I have seen you have compiled from trunk and installed the uboot as 2nd bootloader. Therefore you have changed the kernel_addr ......

BUT ....

you have also to modify the

https://dev.openwrt.org/browser/trunk/target/linux/lantiq/files/arch/mips/lantiq/xway/mach-arv.c

that everything will fit to your new layout.

Take a look at line: 389 - generic board/fs layout function

My propose is that you will taking all as it is from trunk, because here you can grab everytime the newest one without patching internal files.

Hi i have an easybox803 (ARV752DPW22), an easybox802(ARV752DPW) and an Easybox801.
I have build images from trunk for first both.
How can i flash them?
the wiki (http://wiki.openwrt.org/toh/arcadyan/arv752dpw) says i have to flash by using the rescueinterface from the box, but it doesn't say which image i should take.
jffs2-64k, jffs2-128k, jffs2-256k, uImage or squashfs.
My other Router (an TP-Link TL-WR1043ND)  simply needed the squashfs.

Greetings godofdream

The normal choice is squashfs unless you need jffs2.
Squashfs is a read-only filesystem with a good compresion ratio, while jffs2 is read-write and bigger.

During the installation of OpenWRT it creates a jffs2 partition to store the changes and package installation.

Thank you happyelement! I think it would be the best to use the "original" flash layout so i can reflash the box every time without making changes to the code. But i can't find any document that tells me where i have to flash the image (maybe i'm blind). Or is it necessary to replace the original bootloader to fit in this layout?

Thanks a lot!

EDIT: I already tried it so let the adresses in uboot as they are and flash the image at this position, but i had no success because therefore i had to flash ahead the predefined sections in brnboot. That didn't worked for me.

I have tried to search the forums but couldn't find an answer to question:
Has anyone installed OpenWrt to Elisa Kotiboksi (re-branded Bewan iBox ADSL router)?

To my understanding it is based on Infineon Danube. Stickers found on the board saying "ARV7150PW-A-LF-L3". Here are two pictures of the board (click for larger versions):

If someone has managed to boot OpenWrt on this device, how much of the hardware is supported? Do any of the following work?
- Ethernet port(s)
- ADSL
- mini-PCI wlan
- USB

Last time I tried to get the device to boot non-default firmware was over an year ago. I managed to start U-Boot via UART but it couldn't use the ethernet and also detected the CPU or RAM speed incorrectly if I remember correctly.

If I manage to get OpenWrt installed on this device, I'll try to write a wiki article on how to backup the original firmware and flash U-Boot and OpenWrt on it.

I have OpenWrt and uboot on the Elisa box. LAN and USB are working, WLAN not quite, ADSL I cannot test (but it should work).

The problem is that writing to the jffs2 partition is somehow broken, so you cannot save any settings you change. I haven't played with it for almost a year now, so I don't know if the later revisions have some fixes for that problem. There is one PCI related patch that I haven't submitted, it should fix WLAN.

Ethernet in uboot is a bit flaky, but usually works long enough for me to tftp a new image. I use the uboot for the 'EASY50712' target. I also meant to write a wiki article for the device, but then got really busy and the jffs2 problem discouraged me somewhat.

Is a good idea make a wiki for this router despite the problems you have with it. Can you post the hardware specifications, specially the ram chip model?

Maybe your problems with jffs2 are derived from the u-boot you have used. In my case i have flashed in an arv7518 the u-boot for arv752DPW22 due to they have the same definitions (ram, flash and ethernet swith). Try to find other router similar to yours.

Has anyone made any progress with wi-fi on EasyBox 803?

803 has a rt3062 pci wifi chip which is still marked experimental.

i tried it a couple of months ago and it failed horribly

hm, but did you get rt3062 to detect? i think, that it's needed to modify some stuff about config data placement in flash. (?) as mentioned before

i tried on a easy50712 danube eval kit with a rt3062 pci card

OK, thanks for reply!

Also one more question. Is everything working out of the box on the EasyBox 802 on the current state of Trunk?

Hi guys! At last my converter is arrived. At first serial (X4) pinout:
1 - vcc
2 - tx
3 - rx
4 - gnd

Here is uboot's printenv

Is it possible to run openwrt image via tfp without flashing?

you can test a ramdisk iage with the following line

tftp 80800000 uImage; bootm 80800000
