What exactly is it that you are trying to achieve?

It looks like you are running the Toradex Easy Installer from the USB recovery mode which seems to start just fine.

What exactly is it that does not work as expected?

Hi @marcel.tx
I have copied all the files (Colibri-iMX7-eMMC_Console-Image-Tezi_2.8b6) into USB and VNC to flash my kernel image into module.
But I do not see USB getting detected in boot selection. it only shows online images as I have Ethernet connected.

4

And you did previously unzip/untar the image to your USB memory stick which you plug in once the Toradex Easy Installer is started as outlined here?

5

Yes, I did this many times was working earlier.
Even now I can see the installer but don’t see USB image detecting. Seems something went wrong I am trying to figure out…

6

What exact hardware (module and carrier board) versions of things are you talking about? Which exact USB port are you using? What exact USB memory stick are you using?

7

Please find details below:
Colibri iMX7d 1GB eMMC, Colibri Evaluation Board Rev. 3.2.
I tried from all the four USB port.
it’s 16GB Sandisk USB FAT32 (which was working before), I tried another USB too but same error.

[ 2.050666] usb usb1-port1: cannot reset (err = -32)

8

attaching dmesg log for you to understand better. it seems there is some problem in USB port. link text

One thing you could try is first installing the very latest Toradex Easy Installer 2 beta nightly from our CI feed, rebooting and attempting to install your image from the USB memory stick again.

Thank you for the response… I think it’s some board related issue as we did lots of changes… so when I plug two USB (one dummy) it boots.
Thank you & sorry for troubling you.

Thanks for you Input.

Best regards,

i am seeing exactly these logs using a weak power supply.

13

Thanks for your Input. You mean a weak power supply for the USB Hub/Device?

14

With some weak general powersupply i had lying around. 12V/1500mA

Thanks for your feedback.
