FastBoot: My i.MX6D rev1.5 board has 2MB SPI NOR Flash. BootROM loads u-boot from flash and executes it, then u-boot loads uImage and DTB from eMMC using FAT FS. Can i bring uImage and DTB also to 2MB SPI Flash so that uboot need not load those from eMMC?

Hi Igor, Thank you for the reply.

In mfgtool2-yocto-mx6scm-1gb-qwks-rev2-internal-spi-nor.vbs, I saw the following lines:

Line 764: <CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mtd1">write device tree to internal spi-nor</CMD>
Line 767: <CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mtd2">write kernel image to internal spi-nor</CMD>

This script will help me to flash the kernel and DTB to SPI-NOR.

But, I would like to know what modifications / extra coding I need to do in u-boot to make it load the uImage and DTB from SPI-NOR (instead of eMMC), Thanks.

Regards,

Bala
