I just finish the system booting from SD card, and was curious about the booting order.
I just copy the full rootfs from original eMMC rootfs, and modify the root parameter of extlinux.xonf, after power on the system automatically jump to external SD card.
Does it means the TX1 will automatically detect the booting source after power on, and the SD card may be in first order(at least before internal eMMC), then checking the boot folder for relative kernel image, device tree, etc. ?
Could I take any document for reference?
