imx6q boot from SD card

[EinarMar]

Hi

I wanted to ask if it were not possible to boot from a FAT partition on the SD card, i.e. where uboot, dtb, uImage and other files would reside ?

or do I always have to make a binary copy of uboot to the card with 1024 offset ? if so, would I then always have to keep the kernel and bootscripts in the main rootfs partition ?

regards

Einar

Hello,

As with u-boot and kernel, it don't require the file system. When the board is powered up, system ROM will directly read u-boot to RAM and execute it, and then u-boot copy kernel to RAM. But as with rootfs and other files,it must require file system.
