Dual boot options for ROCK64?

[Mrfixit2001]

I've been doing lots of research in preparation of receiving my ROCK64    Has anyone tried dual-booting from a single SD Card yet? I'm hoping to find something that works on this platform that's similar to NOOBS Companion for the RPI, allowing me to easily jump back and forth between LibreELEC (KODI) and LAKKA. Anyone have any experience with this topic yet?

I Wonder the same. Wish to run libreelec and recalbox/lalla/retropie

My guess is you would have to re-compile the kernels to pick the different slice on the flash AND a layer to boot up enough to give you a screen/keyboard to say 'what is the blob you want to load'. Now perhaps someone would write such code for an IoT field upgrade model - 'Boot from this old version/boot the new version' and then that could get re-purposed for what you are looking for or someone wanting:
1) coreboot https://www.coreboot.org/ARM running on the platform
2) NetBSD's model of doing a device tree

The short version is: ARM is not the same as the bios model that brought you dual booting.

that noobs companion or the wd hd  rpi multi boot  code could maybe be modified to set up pine64 devices for multi-boot option.

berryboot source is on github so you could check that out to determine if hack is possible

Any update regarding this? I do not have the knowledge nor skill to make such a thing on my own. I desperately want to dualboot on the eMMC to switch between libreelec and Lakka >.<

[dudemo]

The best way I know to dual boot is to have one OS on the eMMC and another on the SD card. The Rock64 board has a jumper on it to set whether or not it boots from eMMC or SD. Swap the jumper and you can boot SD without having to remove the eMMC card.

ayufan just got SPI working last week - this holds the promise of multibooting different OS'. I wouldn't expect this anytime super-soon, but now at least the possibility is real.

maal, that is really neat. Do you have a how-to link ?

[maal]

No, sorry - setting this up was a process of trial and error.
