Correct setup for u-boot and fstab ? Device not booting

[as365n4]

I compiled arm-trusted-firmware 2.4 and u-boot 2020.10 flashed onto eMMC with the same effect, won't decode extlinux.conf.
Then I compiled arm-trusted-firmware 2.3 and u-boot 2020.10 flashed onot eMMC now it can't see the eMMC.
Arrrrgh

Watched your screencast, many thanks it is appreciated.

Have to see and figure out what I am doing wrong....

Also, I tried to read up on that SCP firmware and how to compile, but despite having musl on the system it won't compile, but this is for later to solve.

Edit:
This is how I compile ATF and u-boot

Code:

git clone https://github.com/ARM-software/arm-trusted-firmware
cd arm-trusted-firmware
git checkout v2.3
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=sun50i_h6 bl31
cd ..

Code:

git clone git://git.denx.de/u-boot.git
cd u-boot
git checkout v2020.10
ln -s /home/youruser/assets/arm-trusted-firmware/build/sun50i_h6/release/bl31.bin bl31.bin
make CROSS_COMPILE=aarch64-linux-gnu- BL31=bl31.bin pine_h64_defconfig
make -j4 CROSS_COMPILE=aarch64-linux-gnu- BL31=bl31.bin
