EEPROM:Read from [factory] offset 0x0,length 0x400.

Federico Corazza · 13 Jan 2017, 15:09

This all started when I couldn't see the omega's wifi. I tried to play with the settings through the command line. After a while I decided to reset everything going into failsafe and doing firstboot. After that the omega wasn't able to boot anymore.

I've read all the other topics in this community, but I couldn't find a solution to this problem.

I tried multiple times to upload the firmware and it ends fine, but when it boots it crashes at EEPROM:Read from [factory] offset 0x0,length 0x400.

I'm using the Mini dock so there shouldn't be any power problem involved.

Any thought?

WereCatf · 13 Jan 2017, 15:11

@Federico-Corazza You say you're tried to upload the firmware, but you don't mention exactly how. Did you try the USB-install yet? See http://community.onion.io/topic/1154/omega-2-usb-firmware-install-after-brick-resolved for details.

Federico Corazza · 13 Jan 2017, 15:15

@WereCatf yes I did that with the latest firmware and the build 143 both worked but it still freezes at the EEPROM.

WereCatf · 13 Jan 2017, 15:22

@Federico-Corazza Interesting. I guess the factory-settings partition has gotten corrupted. Is it an Omega2 or Omega2+?

Federico Corazza · 13 Jan 2017, 15:29

@WereCatf Omega2+

WereCatf · 13 Jan 2017, 16:00

@Federico-Corazza Mind trying to flash my firmware-image at https://dl.dropboxusercontent.com/u/11811685/lede-ramips-mt7688-omega2p-squashfs-sysupgrade.bin via USB and seeing if it boots up any better? If it boots, then we can proceed to try and repair the factory-partition.

Federico Corazza · 13 Jan 2017, 16:50

I flashed the firmware. When it reboots it reaches this point:

and then freezes again.

@Federico-Corazza Well, that's poop. I guess I need to strip some stuff out and compile a new image for you -- perhaps stripping out all the networking-stuff would let you get into the OS, at which point backing up the current factory-partition and writing a new one would be easier. Alas, I've got a lot of stuff going on at the moment, so I'll have to get back to you later.

Federico Corazza · 13 Jan 2017, 17:05

@WereCatf Yeah no problem, thanks.

Federico Corazza · 19 Jan 2017, 16:05

This post is deleted!

Federico Corazza · 19 Jan 2017, 18:09

@WereCatf Did you manage to work on it?

WereCatf · 19 Jan 2017, 18:19

@Federico-Corazza I forgot about it completely, but I'm just compiling an image and I should have something in ~15 minutes or so.

WereCatf · 19 Jan 2017, 18:45

@Federico-Corazza Okay, here is a link to the image: https://dl.dropboxusercontent.com/u/11811685/omega2-eeprom/lede-ramips-mt7688-omega2p-squashfs-sysupgrade.bin

There is no WiFi, no ethernet enabled. Take a backup of your current factory-partition with dd if=/dev/mtd2 of=/whereeveryouwant.mtd2and copy it to a USB-stick or microSD-card before flashing anything. You can then try to flash the contents of my Omega2's factory-partition with mtd -r write /factory.mtd2 factory -- the file is already included inside the image. Then you can try flashing official firmware and it'll hopefully work, though your MAC-address might have changed.

@WereCatf I'm still having issues.
I flashed that image from dropbox but it freezes after:

Federico Corazza · 20 Jan 2017, 23:31

@WereCatf I flashed the imaged a second time and got it working, but when I loaded the latest firmware it froze again at

[ 17.490148] EEPROM:Read from [factory] offset 0x0,length 0x400.

WereCatf · 20 Jan 2017, 23:35

@Federico-Corazza Are you absolutely certain your power supply is good?

Federico Corazza · 21 Jan 2017, 09:06

@WereCatf how much can the omega withstand with the mini board? Can I use the power supply of the raspberry pi ? (5V 2.5A)

WereCatf · 21 Jan 2017, 09:08

@Federico-Corazza Yes, you can.

Federico Corazza · 21 Jan 2017, 16:02

@WereCatf It works!

Thank you very much!
I apologize if I made a bigger problem than it really was.

Chris Stratton · 21 Jan 2017, 23:28

Working with some similar MT7688 hardware, I've also seen that an under-rated power supply can cause unexpected reboots, particularly when the wifi subsystem starts up.

Overall power consumption of these systems is low, maybe a watt and a half, but there seem to be some peak loads where a supply with poorly responding regulation can trigger a crash and reboot.

Maarten G · 22 Jan 2017, 21:46

Hello,

I seem to have same issues you have, I cannot get wifi working. However I dont think it is power related in my case. I have tried powering from my laptop and seperately from a phone charger rated 5V/1A on the micro usb on the docking board. But the issues presists...

I've got the same thing this person posted at startup: https://community.onion.io/topic/1082/help-omega2-not-working/2 with the stack trace.

I tried setting up wifi connection over the web but it just would not work and fails every time I try. Then I tried it over serial/ssh and I get this message when i tried to restart wifi with /etc/init.d/network restartafter I verified all settings where ok in /etc/config/wireless. Then the same "EEPROM Read from" happens and the restart seems to fail?
