LS1012A TWR boot from SD problem

dwokke — Mon, 20 Apr 2015 13:48:13 GMT

Hi all,

So I build a new kernel for the LS1021ATWR board using the QorIQ SDK 1.7. As far as I can tell this has been build without a problem.

Now I want to run the new kernel on the LS1021atwr board via a SD card. For this I followed the manual and copied all files to the SD card, maikng sure the uImage and uImage.dtb are in the boot folder.

Booting the board now hangs almost directly when the SD card is read.

The following shows up in the terminal on the host.

Any idea on what I'm doing wrong. SOmething I failed to do first. I'm completely lost as this is my first time using embedded linux.

Did you follow the steps from SD Deployment? If, yes, could you share your uboot env (printenv in uboot console).

Look at the following page:

http://www.freescale.com/infocenter/index.jsp?topic=%2FQORIQSDK%2F6346899.html

Do you use similar command sequence for SD Deployment?

OK so I got a bit futher.

Using the run sdboot command now gives me the following:

-----------------------------------------------------------------------------------

This definitely shows it is reading the SD card with the image I build. However it gets stuck on the starting kernel ...

Any ideas on this?

I met the same behaviors some times ago and formatting the sd card resolved the problem.

OK so I found the issue. I tried to build the kernel with CPU freq. Which apparently is not supported by the LS1021A.

My bad!
