Dear Arun,

When I tried to replicate this while carefully following the course video instructions, there was no such error message.

Are you still experiencing the same problem or have you managed to resolve this?

[Arun2023]

Hi Dodoolas,

I followed the video instruction 5 times and didn't worked, so came for help.

This may help - you may be using different source code: https://designhelp.fedevel.com/forum...ot-openrex-sbc

Hi Robert,

Thanks will try this option, I am testing the hardware which was purchased from you along with course. Will keep you updated.
Thanks.

Does SD card is corrupted??
Not showing any sdb1 details but when i check the drive, SD card showing two partition. Same image i have attached for your reference.

[robertferanec]

did you try df command? the message says sdb2

[Arun2023]

Hi Robert,

df command?

Should i try any of this command.

[robertferanec]

Please, post here exactly the output what you see in terminal + lesson number + time in the lesson where you are watching.

[Arun2023]

Hi Robert,

The output shown in the terminal is attached as image for your reference, the Lesson-2 (LEULY-02) video and timing is from 12.53 to 23.21

[robertferanec]

this is different problem, not sdb1/2

did you try printenv command in uboot?

you may have something wrong in your configuration. it looks like env parameters are not set. If you like, you can just continue following the course and later you will understand how to fix this. If you are curious, you can have a look at Lesson 4 00:36:01 Environmental parameters inside uBoot source code

[Arun2023]

Dear Robert,

Ok, i have not tried the printenv command in uboot.

As per the lesson video - 2, the board will boot in the video but in my case. It stops as per the image upload in my previous post.

Should i skip this terminal boot up and continue the lesson videos?

[robertferanec]

please, try printenv command first and post the output here

[Arun2023]

Dear Robert,

I tired printenv command in uboot and below images came.
Shall I continue with the lesson-2 now?

[robertferanec]

you can see, there is no bootmmc defined, but I am not sure why. do you see it in source code? (as described in lesson 4?)

you can continue without it
