N2+ USB ports non functional in some OS but fine in other

Post by darioush »

I have 2 N2+, one of them 2GB version and REV 0.6 the other 4GB version and REV 0.5.
On Android Pie 9 downloaded from "https://wiki.odroid.com/getting_started ... _providing"
My REV 0.6 has no functional USB ports but all USB ports are functional on REV 0.5,
and if I use UBUNTU 20 from the same source I have no working port on both my N2+ REVs,
the only way I can use any of my N2s with working USB ports is to use the eMMC card that I purchased from hardkernel and even that one only works with my N2+ 2gb REV 0.6 and its ubuntu 18.04.4 LTS.
I experienced this issues when first I tried to upgrade to ubuntu 20.
I am not an experienced user and just started to use odroid products, but this seems to be a software issue not hardware but again I might be wrong.
Please let me know your thoughts.

Moved from XU4 sub-forum.

Anyway, do you use the SPI Petit-boot mode? Let us know the slide switch position.
If yes, update it first.

Hi, Thank you for correcting my mistake.
I have used Etcher for writing the image to eMMC cards, and slide switch was on eMMC originally but since I have used other position too which makes no difference ultimately.

Quick update.
I have tried android OS too and i have no function on my 4 USB3.0 ports although OTG port is working.
I also tried CoreElec software and All ports are functional.
I have been in touch with few friends who have the older REV. they had no problem with their USB ports although none of them have upgraded their OS, which I advised againt doing so.
I have tried so many different OS versions now that I am ready to give up on this and of course I am confident the hardware has no issues and this is a software malfunction.
Can someone please provide an old software wich they know it works on 2021 REV 0.6 regarding USB 3.0 ports?

Have you tried this latest Android image?
https://wiki.odroid.com/odroid-n2/os_im ... 4_20210930

Meanwhile, we will try that image on a N2+ 2GB REV 0.6 board.

We've tried the latest image ubuntu-20.04-4.9-mate-odroid-n2-20210830.img and selfinstall-odroidn2-144-64bit-20210930.img.
USB 3.0 ports are working fine with two images.
Our sales team will contact you soon.

BTW, do you use an official 12V/2A PSU?

Hi and Thank you,
But it is still not functioning at all times for me it worked once or twice but it has stopped again,
as i mentioned before i know it is not hardware as everything works fine with CoreElec software.
Please guide me through this, its being over a week this is giving me headache, also i have not had any contacts from anyone as you said above!!!

We tested those images on a 2GB N2+ board and there was no issue at all.
I think your board might be on an edge condition of the hardware problem.
Install the Mate image again and show us "lsusb" and "lsusb -t" and "dmesg" outputs via SSH access.

We tried to contact you. But, we couldn't find your order information with your forum ID.
Send an email to "odroid at hardkernel dot com" with a link of this thread. They will help you.
