I did several tests and the problem was fixed after using the above device tree. But there seem to be some problems with the U-Boot. U-Boot SPL 2023.07.02-armbian (Sep 19 2023 - 18:28:54 +0000) DRAM: 4096 MiB Trying to boot from MMC1 I used an SD card to boot and often the card would not move after the above print after reboot, it seems that the identified DRAM capacity is wrong.

I don't know if you're still talking about Ethernet not working after hot reset. The kernel I use is 6.1.54-current-sunxi64, After a hot reboot, wifi automatically connects but Ethernet does not work. I connected the network cable, HDMI cable, serial cable, and I used a regulated power supply with a limited power of 5V1A. Hope to help troubleshoot this problem. armbianmonitor -u: https://paste.armbian.com/iwufeqaxit @Gunjan Gupta

I tested it using Armbian 23.11.0-trunk.125 Bookworm with Linux 6.1.54-current-sunxi64 and the problem was fixed.

Thank you for your support, I will update the kernel tonight to test it. But i would to ask how I update them from beta repository. Choose another kernel through the armbian-config->System->Other? What do i need to configure to point to this repository?

I'm using Armbian 23.02 Bullseye CLI. I didn't want the HDMI to show the boot system log and TTY1 login screen. According to the armbian documentation, I changed "console=both" to "console=serial" in /boot/armbianEnv.txt. I checked /boot/boot.cmd related to console, and I confirmed that this modification is OK, but it cannot start, uboot printed "Starting kernel..." After that, there is no output, and the power supply is only 5V 170mA. The following is the printing of the serial port. If anyone has been in a similar situation, please give me a little help, thank you very much.
