Problem implementing embedded linux on MCIMX7SABRE

sam_peetermans · ‎02-10-2020

At the moment i am really stuck while getting started with the MCIMX7SABRE development board.

I completed the getting started guide from the following getting started guide - link and everything seems to be working fine.

When proceeding to the next step "2. Embedded Linux" i cant burn the NXP Linux BSP image to the board.

I tried it on both linux and windows. Both seem to be stuck around the same step.

I configured the boot switches to the SDP but the board always seems to be booting from the SD card, no matter how the boot switches are configured.

So to force the device to boot into the SDP mode i leave the SD card out.

For linux i have a host platform with macOs and i use virtualbox with ubuntu 18.

Below are the logs from the serial output:

I seems to be stuck on that step, and the terminal output is:

All resources utilized in the proces where listed in the getting started process from the first link.

The 3 main questions that i have:

What do i need to do to make the SDP proces proceed?
Is it normal behavior that the boot switches do not seem to influence the boot behavior of the MCIMX7SABRE platform?
Is there a way to confirm that all the functionality of the board is ok, and that there are no defects?

Hello Sam,

You need to reburn the sdcard with 4.14.98 BSP Demo images, apparently you sd has a problem so just download the BSP and burn it again.

Hello,

That was a solution that i tried myself, and succeeded at it.

But this does not fix or explain the problem why the SDP proces/uuu for loading the image is stuck and does not work (as can be seen in the logs).

Do you have any explanation for that?

I would really like to be able to utilize the SDP and otg port to load the image as described in the getting started guide.

Best regards,

Sam Peetermans
