Building u-boot for A20-OLinuXino_MICRO-eMMC fails to apply overlays in uEnv.txt

[luimarma]

Hello,

I am trying to compile u-boot for the A20 Olinuxino micro with emmc, for the current Bullseye image with olimex 5.10.180-olimex kernel.
The reason is to avoid some drivers checking and speed up booting.

I have started just compiling with the default configuration, but the resulting u-boot is not applying the overlays in /boot/uEnv.txt

The procedure I have followed is the next one:

I have downloaded the source from here, https://github.com/OLIMEX/u-boot-olinuxino
Next applied the following commands to set the default config and compile.

#make CROSS_COMPILE=arm-linux-gnueabihf- distclean
#make CROSS_COMPILE=arm-linux-gnueabihf- clean
#make CROSS_COMPILE=arm-linux-gnueabihf- A20-OLinuXino_MICRO-eMMC_defconfig
#make CROSS_COMPILE=arm-linux-gnueabihf-

And finally to install the new u-boot and make sure that all is consistent, I did the following.
copy u-boot-sunxi-with-spl.bin to /usr/lib/u-boot-olinuxino/a20-olinuxino/u-boot-sunxi-with-spl.bin
#u-boot-install /dev/mmcblk0
#/usr/sbin/update-initramfs -u
#/etc/kernel/postinst.d/uboot-fit 5.10.180-olimex

When booting with the new u-boot the board boots, but I no longer see the overlays reflected at uEnv.txt loading, before I could see the following output after the FIT image overlays:

With stock u-boot and compiled one I can see the uEnv.txt loading BTW.

Boot script loaded from mmc
Checking for /uEnv.txt...

What am I missing?

Thanks in advance,
