I just had a look at Diet Pi and it appears that it there is a tow-uboot bin in the image. Had a go anyway but no go. My understanding is that emmc boots if spi is clean, spi boots if u-boot ir some other such on board and if spi is clean and emmc is clean or not present then rk3399 will boot from an sd card. I expect I'll have to do a mask mode manually.
