This board does not boot from sd, only from SPI NOR.

Could you please let me know how it was tested?

It would be nice to add a README that tells how to flash the SPI NOR.

There is a 'workaround/patch' available from Freescale which switches the board to SD boot. It's a small program written to the SPI NOR replacing the U-Boot in SPI NOR, which then itself jumps back to the SD boot routines. From user point of view the boards boots from SD then. With a small, invisible indirection via the SPI NOR.

Best regards

I would be glad to test the mx6sabrelite U-boot patch if you can provide me the FSL workaround/patch that replaces SPI NOR with SD boot.

Hi Dirk,

But if I really understand, the board boots always from SPI NOR, in other words the SPI NOR cannot be empty, as it can be if the board boots drirectly from SD.

Then we need a document / README, as remarked by Fabio, to describe this process.

Yes, this is correct. The ~20 line workaround is executed first in the SPI NOR and then jumps back to the SD boot routines. Hopefully there will be updated/modified boards in the future were the boot mode is configurable, again.

Fabio: Do you think you could provide such a readme after your tests?

Many thanks

Yes, updated boards will allow booting from SD card directly.

Or maybe we can wait for the new boards to become available.

Let me discuss this option internally.

Add the initial support for Freescale i.MX6Q Sabre Lite board

Please note that this patch relies on the basic i.mx6q core support introduced with the patch series

http://lists.denx.de/pipermail/u-boot/2011-November/111163.html

So it would be nice if this patch could be handled together with the above patch series as proposed in

http://lists.denx.de/pipermail/u-boot/2011-December/111881.html

Many thanks

Dirk
