  1. I finally got around to playing with this again and spent a few hours. The upshot is the kernel in multitool can recognise the SD card perfectly fine, however the u-boot image does not. When I previously had the multitool booting with the USB workaround the kernel was running from the SD card, u-boot was being launched from the SD card but u-boot itself can not see the SD card, by having the USB stick in the OTG port u-boot can then read that and read extlinux.conf to proceed booting multitool from the SD card. Eventually after looking through the multitool source (thank you for li
  2. @jock Thank you! That was enough of a clue to get this working (albeit an awful hack), while the loader on my SoC seems to not want to boot from a USB device I figured out that if a USB flash drive with the extlinux.conf is in the OTG port the boot process can proceed as expected. This workaround is fine, though I couldn't find the source for multitool to start debugging further. The box I have is marked externally as a MXR 4k bought from a seller on Amazon UK September 2016. The board however is marked 'MXQ-RK3229-D16', version '0.9A' on the silkscreen. With a whole bunch of missi
  3. I'm having an issue getting the multitool SD card image to run on my RK3229 nand board, hoping someone may be able to help.
