Kernel boot problem

Hello,
I have an A20 board based on LIME2, when I try to boot up an armbian image it gets stuck at starting kernel. One thing that catches my attention is Failed to set core voltage message. I have checked the I2C line to see if the AXP209 was responding to voltage change and it was not. Any ideas where should I look into.

Do you found the solution?
I have the similar problem, I have the network issue

Net:   Could not get PHY for ethernet@1c50000: addr -1
eth1: usb_ether

and I have no ethernet connection. No device... No leds blinking...

Which Linux image are you using? Ethernet is supported in official images, maybe check this document:

What troubleshooting steps can I take if my A20 board based on LIME2 gets stuck at "starting kernel" when booting an Armbian image, especially after seeing a "Failed to set core voltage" message and confirming that the AXP209 is not responding to voltage changes on the I2C line?

Which board exactly do you have?

Does the board work with Olimage? Always first test with Olimage.

Maybe try with the Armbian image from our FTP, but notice that we no longer support that image.
