Orange PI 4a on eMMC only half of RAM

orange4A

Hi!
When I install the official debian image on emmc (using the command “bash nand-sata-install”) 2gb of the 4gb RAM is left. Can anyone suggest a solution to this problem?

I found a solution to the problem:

1. Open User Manual and find the Compiling u-boot section
2. Run the build.sh script
3. sudo dpkg -i linux-u-boot-current-orangepi4a_x.x.x_arm64.deb
4. sudo nand-sata-install
5. reboot

If anyone needs it, I'm attaching the assembled u-boot

The issue where only 2GB of the 4GB RAM is recognized after installing a Debian image on eMMC using nand-sata-install on an Orange Pi 4a (or similar single-board computer) could stem from several potential causes, Escape Road including bootloader configuration, kernel limitations, or hardware-specific settings.
