- Standard UEFI boot environment (Coming soon, check: https://developer.solid-run.com/knowledge-base/lx2160a-cex7-uefi-and-sbsa-status/)
The easiest way is to flash SD card with image provided by Solid-Run (including u-boot) at https://drive.google.com/file/d/1AGdWMSh9lLEYpUeX2dAinQTjzvvi5pMn/view?usp=sharing which contains some firmware and U-Boot.
Boot order from U-Boot is: usb0, mmc0 (SD card), scsi0 (sata), nvme0
Otherwise, you can give a try to current WIP UEFI firmware, by building it manually from https://github.com/SolidRun/lx2160a_build with runme.sh (edit header to set required options).
Then, please use the EFI image from Installing openSUSE ARM for AArch64 EFI based systems and copy it to USB or SATA storage (PCIe/NVME is supported on Leap/SLE only and SD read/write line is broken on hardware, so SD is read-only).
If you use u-boot, you will need to provide a DTB as U-Boot does not provide it. Some DTS are available at http://git.armlinux.org.uk/cgit/linux-arm.git/tree/arch/arm64/boot/dts/freescale?h=cex7
git clone git://git.armlinux.org.uk/linux-arm.git --branch=cex7 --depth=1 pushd linux-arm make defconfig make freescale/fsl-lx2160a-honeycomb.dtb # DTB available at arch/arm64/boot/dts/freescale/fsl-lx2160a-honeycomb.dtb popd
Copy the dtb to boot partition and add the following line for grub menu:
and start with ctrl-x.
