U-boot netconsole on the AR-150

Does the u-boot on the AR-150 include netconsole? I was able to get the u-boot serial console but it looks like there are some errors in data transmission. I get partially garbled text. Linux console over the serial port works just fine, but the u-boot console doesn’t. Any help/tips on how to use it would be greatly appreciated

It does include a netconsole. However the netconsole is never tested by us. Someone used and reported it works.
