write in detail what steps you did and why the installation failed.
which power supply do you use ?
There is no USB startup support in this bootloader and there are hidden bugs, if there is a problem with the system on NVMe, you will not be able to start the system from the SD card for repair (you will have to physically disconnect NVMe to start the system from the SD card).
The log specifically states that there is a problem with the firmware file (most likely it is simply not in the specified location). Try installing the full firmware package via armbian-config or apt\synaptic or copy it manually
