I want to try tftp boot… So I burn a ubuntu image on EMMC (4.9 kernel, uboot 2015)
The dev console was connected to PC using serial - usb connverter
while booting I interrupted booting by pressing enter…

now I have setup tftp server in my desktop PC and kernel files in the TFTP folder when I set the device and server IPs and try to save env I get the error error get partition info failed !!

also I am not able to access my tftp server after setting device IP and server IP
