I know that, this just adds some cost and complexity for installation. I hope that some day nvme will be supported in SPI and there will be no need for SD or eMMC.
Have You convinced firefly for non-emmc versions? are there chances for that?
No worries, probably it requires some extra work and more kernel config. I will come back to this after new year. For now I need to focus on rk3399 (t4, rockpro64 and r4s).
Thanks for your time
