@Der Geist der Maschine Right, let me qualify that. If you update uboot and something goes wrong, then its not like messing up BIOS or even GRUB on a standard PC. In fact, its likely that you'll be able to reflash uboot again to the same eMMC using some method we'll dream up (likely some autoscript running from SD like ayufan did for the Rock64/ Pro). And if all goes wrong, then you can still pull data off of the eMMC module by either booting from SD and mounting the rootfs partition of the eMMC or removing the eMMC drive and pulling data from it manually using a USB->eMMC adapter.
And yes, I too find the design choice of Rockchip to have eMMC boot prior to SD a bit peculiar.
