T1042 RDB - 64b Destination Host Unreachable

[yusufalti333]

Hello nxp community,

I am planning to use TFTP for my T1042 RDB - 64b board to flash yocto generated U-boot and linux kernel etc. . Firstly i wanted to check network communication so I decided to send ping from a local windows machine. When I try to send ping, it replies to windows machine as 'Destination host unreachable'. I am using ETH0 port and board IP is 192.168.10.40. PC IP is 192.168.10.50 and subnet of both devices are 255.255.255.0. I also defined a gateway for both devices as 192.168.10.1.

I am using SDK 2.0 - 1703 and followed the steps described in https://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf .

What is the problem here. Any suggestions ?

Hello Yusuf Altıparmak,

Would you please provide your whole console log?

Please check whether there is networking problem under u-boot first.
=> setenv ethact FM1@DTSEC1
=> setenv ipaddr 100.1.1.110
=> ping 100.1.1.1
Using FM1@DTSEC1 device
host 100.1.1.1 is alive
=>

Thanks,

Yiping

This was working exactly like you said. I was trying to reach board from my Own PC. I can not do it while U boot is activated on board (Not Linux). Then I activated Linux and set one of my ethernet ports as 192.168.10.40/255.255.255.0 and set it up. Then it worked. I reached board from my own PC. But U-boot is still unreachable with ping command.

Hello Yusuf Altıparmak,

U-boot cannot receive networking packets  ping from outside.

Thanks,
