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

    @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.

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

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

    @Federico-Corazza Yes, you can.

    @WereCatf It works!

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

    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.

    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?

    Does anyone know what the cause of this problem is or how I could get my Omega2+ connected to wifi?

    @Maarten-G Don't try to hijack threads. Your device isn't crashing, so it's not the same issue.

    Yes that does seem like a different issue, though the thread title is a bit unfortunate, it seems the EEPROM message is routine verbose output, not indicative of any issue.

    But if the message is the last thing seen before a problem, or comes up in a search result, it's easy to associate it in the mind.

    @WereCatf Apologies, not here to hijack a thread. I figured the EEPROM: Read from [factory ] error is/was an issues and since I got the same thing I thought it would be more helpful to post here, instead of making a new thread. Which was stated in the guidelines to not make a new thread and rather post in another user thread if I'm courteous and in the same situation.

    I'd try looking around for other issues, testing the things that I can and make a new thread.
