There is a full-functioning Ethernet device driver available in the kernel tree for the i.MX RT1050RT10XX. The device driver is linux/drivers/net/ethernet/freescale/fec.c configured in the kernel using the CONFIG_FEC build time option in Device Drivers -> Network device support -> Ethernet driver support -> Freescale devices -> FEC ethernet controller (of ColdFire and some i.MX CPUs).
...
Let's test the TCP/IP stack on the i.MX RT1050RT10XX.
From the development host validate that the i.MX RT1050 target is visible using ping:
| Code Block |
|---|
$ ping -c 5 192.168.1.86 PING 192.168.1.86 (192.168.1.86) 56(84) bytes of data. 64 bytes from 192.168.1.86: icmp_seq=1 ttl=64 time=20.7 ms 64 bytes from 192.168.1.86: icmp_seq=2 ttl=64 time=5.72 ms 64 bytes from 192.168.1.86: icmp_seq=3 ttl=64 time=5.84 ms 64 bytes from 192.168.1.86: icmp_seq=4 ttl=64 time=5.72 ms 64 bytes from 192.168.1.86: icmp_seq=5 ttl=64 time=6.30 ms --- 192.168.1.86 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4005ms rtt min/avg/max/mdev = 5.715/8.851/20.692/5.924 ms |
ping the development host from the i.MX RT1050target:
| Code Block |

/ # ping -c 5 192.168.1.89 PING 192.168.1.89 (192.168.1.89): 56 data bytes 64 bytes from 192.168.1.89: seq=0 ttl=64 time=4.916 ms 64 bytes from 192.168.1.89: seq=1 ttl=64 time=5.071 ms 64 bytes from 192.168.1.89: seq=2 ttl=64 time=5.286 ms 64 bytes from 192.168.1.89: seq=3 ttl=64 time=5.226 ms 64 bytes from 192.168.1.89: seq=4 ttl=64 time=5.595 ms --- 192.168.1.89 ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max = 4.916/5.218/5.595 ms |
On the target, start the telnetd daemon to allow connections to the i.MX RT1050RT10XX:
| Code Block |
|---|
/ # ps | grep telnetd 100 root 864 S telnetd 102 root 864 S grep telnetd / # |
...
Connect to the target from the development host using ssh. The first connection takes several seconds to establish as the i.MX RT1050 RT10XX runs computation-extensive key calculations. Again, enter 123 on the password prompt:
...
From a local host, open a Web browser to the i.MX RT1050 target and watch the demo web page provided by the target. The i.MX RT1050 target shows the current time and date as well as the list of the currently running processes:
