Overlay uartC (/dev/ttyAML4) not working

I need a UART in my work.
Added uartC overlay via armbian-config (UART_EE_C - /dev/ttyAML4)

However, after booting, the device /dev/ttyAML4 does not appear.

 

The download log contains the following information:

 

Using the kernel-provided DT meson-uartC.dtbo overlay
fdt_overlay_apply() error: FDT_ERR_BADMAGIC
base fdt has no node /__symbols__
make sure you compile with -@

Error applying DT overlays, restoring original DT

 

I would be grateful for any help!
