[beagleboard] Support: Uboot TFTP Configuration in BBB

2019-03-09 Thread Pon Senthil Rajan Jeyaraman
Hello All,

I'm trying to configure network and TFTP in the uboot of eMMC of BBB with 
the below uboot commands.

setenv autoload no
dhcp
setenv netmask 255.255.255.0
setenv dnsip 192.168.0.1  
setenv gatewayip 192.168.0.1
setenv ipaddr 192.168.0.120 
setenv serverip 192.168.0.6 - (my PC address)
saveenv

after saving the above environmental variables, Tried the below steps to 
ensure the connection between BBB and my PC.
1. ping from my PC (192.168.0.6) to BBB - destination is not reachable.
2. TFTP also ends with result - "ERROR: The remote end did not respond in 
time."

why I'm not able to ping to the configured ipaddress of BBB, and I'm also 
not able to see the BBB entry in my router active list.

I have already worked with tftp in other boards in past, but for BBB not 
sure what i'm missing.
Could any one provide a suggestion.

Thanks.

Check your numpy version (should be 1.12.0 or higher)
