Sure, if you "patch" u-boot and "build" it for that situation, it would work. The current U-Boot binary we ship for the debian images does NOT support booting from the esata drive. Initially we did support loading u-boot from the microSD and then scanning the sata for a secondary rootfs but ran into compatibly problems with crappy sata drives.. > Do I need to install this > separetly?

Here's the documentation: What you "can" do, start with our image on the eMMC, run the 'mv_rootfs_dev_sda.sh" script found under /opt/scripts/tools/non-mmc-rootfs/ https://github.com/RobertCNelson/boot-scripts/blob/master/tools/non-mmc-rootfs/mv_rootfs_dev_sda.sh After this you have two options to load from the sata drive: Option 1: (u-boot, kernel, device tree is loaded from eMMC/microSD, but rootfs = sata) Then edit /boot/uEnv.txt and have the uuid=ZYZ point to your /dev/sda1 partition. Option 2: (u-boot, is loaded from eMMC/microSD, but sata = kernel, device tree, rootfs) Follow these directions: http://eewiki.net/display/linuxonarm/BeagleBoard-X15#BeagleBoard-X15-Bootloader:U-Boot and change these lines in the patch: https://github.com/RobertCNelson/Bootloader-Builder/blob/master/patches/ti-2017.01/0001-beagle_x15-uEnv.txt-bootz-n-fixes.patch#L1442-L1444 + "echo usb_boot is currently disabled;" \ + "setenv interface scsi; " \ + "echo scsi_boot is currently disabled;" \ to: + "run usb_boot;" \ + "setenv interface scsi; " \ + "run scsi_boot;" \ and the U-Boot loaded over the microSD/eMMC will scan the usb bus and sata bus.. (usb bus powers the sata bus, so it has to be run first).. But be forewarned, Option 2 turned out to be a little un-reliable, especially which cheap sata drives... (things might get better when we jump from u-boot v2017.01 -> v2017.11 in the coming weeks) Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
