I had lost network interface when upgrade linux-image-vendor-rk35xx to 24.8.4 from 24.8.2 and reboot.
I had downgrade to 24.8.2, then I got network interface.
linux-dtb-vendor-rk35xx 24.8.4
linux-image-vendor-rk35xx 24.8.2
In other way, I had update bootloader by armbian-config to MTD-Flash then I got network interface.
but, I had trouble in HDMI output that not display for two display, display only one.
armbian-config 24.8.4
linux-dtb-vendor-rk35xx 24.8.4
linux-image-vendor-rk35xx 24.8.4
