Booting i.MX6 Android from NOR FLASH

[mike_sims]

Hi,

I have questions about booting Android from NOR on a Sabre AI (imx6dl CPU2) board.

I am preparing a SW Build for our custom HW design by using the SabreAI board.   I have built the sw provided by NXP to boot Android from SD Card (this works well).  I am trying to adapt this SW to put u-boot and the boot image on the on-board 32MB NOR, but I do not see a way in U-Boot to use BOOTA from NOR.   Is U-Boot the right bootloader to use to boot from NOR??

For now, I am OK with having the remaining partitions on SD Card.  In our custom application, I would want the boot, bootimage, recoveryimage, and system partition on NOR.   Will I need to modify the FSTAB, INIT*.RC, or System Image to move these partitions from SD to NOR??

Thank you in advance for your answers...

Regards..

Thank you for the responses, but none really address the question of how to use BOOTA with NOR.

After much digging, there is a way to implement this.  BOOTA takes an address as a parameter.  So, if a BOOT.IMG is programmed into flash at say address 0x08080000, I can use the U-Boot command BOOTA 0x08080000 to correctly load this image and boot...

Hope this helps someone else....

Regards.

Android MM6.0 release doc , for SabreAI board , boot source tested are :External SD and NAND.

For Linux 4.1.15 release note , there is u-boot  configure for SabreAI board boot from nor flash.  Refer it to generate u-boot which could boot from NOR flash.  For Kernel and other image storage partitions, one could take the android release user guide doc. for reference.
