... we use amlogic-boot-fip https://github.com/LibreELEC/amlogic-boot-fip/ and the instructions from https://github.com/u-boot/u-boot/blob/master/doc/board/amlogic/odroid-n2.rst to build u-boot & sign it.

This works & boots fine on the SD card, but on the emmc, while u-boot starts successfully,

... the boot to the emmc fails with "No partition table - mmc 1"

Using msdos partition table format.

This works fine on the MicroSD but not EMMC. I think it might be due to faulty emmc clock settings in mainline u-boot
