Hi, i have a strange problem.

1. eoc-5610, in sealed box.
2. opened at client site, do some testing (checking coverage, transmission speeds, etc).
3. i've put it back in the box, going back to the lab to configure it for the final installation.
4. arrived at lab, open it, power it up, only PWR led on, and WLAN with fast and random flashing. No link at LAN port. Reset does not work. Looks like a bricked/faulty device. The device has been powered for 30 minutes at first time, after two hours, does not work anymore.

What should I do ?
Try to update/rewrite firmware ?
Send it back for warranty ?

The LAN port is not working, and the WLAN it's not available, either in 2.4 or 5ghz

any suggestions appreciated.

Ive the same problem ... what did u do to solve the problem?

[Sash]

u guys can try to use the redboot recovery tool but 4 me it sounds like a hw brick

[meno]

yeah sash.. no lan.. nothing.. I send to my provider.. and they say it has lan port burned, so they cant change it.. so.. now.. I'll try the JTAG recovery.. sash do you have the redboot files of this unit??

[Sash]

lan port burnt means a hw damage. its a doorstop now. the only possilbe way to get it live is to desolder the ethernet phy and add a new one. but there can be even more damaged! u did use the wrong psu or poe injector.

[meno]

no no no.. u didnt understand me.. I tried to flash the oswave firmware.. and then the unit bricked.. so I sent to my provider.

so as not link the etherent port.. they say, has a lan port damaged, but I know its software.. mean the bootloader or the firmware.

[Sash]

u must check first if the eoc even has an jtag port. else u can save your time.

[meno]

yeah.. I checked for the JTAG port, but I cant find it. I just find the serial port...

brosky.. we have bootloader broken.. now I desolder the flash Chip of my EOC-5610.. I split the bootloader from ubiquiti powerstation5. its the same processor AR2313A

so my plans are to use a dlink DWL-2100AP as a jtag flasher.. I going to build the wiggler cable again.. Ive experience with RTL8186 + JTAG

I will post if I can revive..

please dont use the powerstation 5 bootloader. same chipset, yes. but the powerstation has 16 mb ram instead of 32. so the dram controler will not get correct initialized. the ram values are hardcoded in the bootloader. so you cannot use it

[meno]

thanks for your warning brainslayer.. I write to engenius support but no answer, and then oswave too, nothing.. and then I thought of this extracting from the bootloader from PS5

wo mr brainslayer what do you suggest?

[meno]

this thing I did to trying recover back my unit..

I desolder the flash IC and solder into a WRT54Gv6 to use a JTAG flasher.. because I didnt found the jtag pinouts.

then I flash the cfe.bin to try if I will work... and then worked.. I probed with tftp and worked perfect...

now the main propose, 1st time I flash the OSWave_to_Original_Firmware_EOC5610.bin.. using hairydairymaid.. but as it doesnt support my flash memory.. I use MX29LV320 (4mb) and didnt work.. 2nd time.. I flashed the PS5 bootloader.. again didnt work..

the problem I guess is the hairymaiddairy program, cause doesnt include the MX29LV640 flash support (8Mb)

so.. guys what do you think?

and what do you suggest me?

Thanks

[Sash]

use tjtagv2

[Tornado]

tjtagv3-RC1 supports that flash chip
