Test item
Network inferface test
MYZR-IMX6-EK140 support one 100 Mbps ethernet interfaces.
Interface property
ENET Interface position：P2
Test method
1）Configure computer IP
Set wired network card IP of computer as 192.168.18.18
2）ENET connect test
Connect lan line: connect “eth0”on evaluation board with corresponding wired network card interface on computer with lan line.
- Set evaluation board IP：
# ifconfig eth0 192.168.18.100
- Execute test command：
# ping 192.168.18.18 -c 4
- Observe test result：system will output message like following:
PING 192.168.18.18 (192.168.18.18): 56 data bytes 64 bytes from 192.168.18.18: seq=0 ttl=64 time=2.848 ms 64 bytes from 192.168.18.18: seq=1 ttl=64 time=0.496 ms 64 bytes from 192.168.18.18: seq=2 ttl=64 time=0.478 ms 64 bytes from 192.168.18.18: seq=3 ttl=64 time=0.518 ms --- 192.168.18.18 ping statistics --- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max = 0.478/1.085/2.848 ms
- Test result：“0% packet loss”represent test passing.
USB Test
Interface attributes
Interface location: P3
Test Method
1）Start test
Insert USB device into USB port on base board，system will output message like following：
usb 1-1: new high-speed USB device number 2 using ci_hdrc usb-storage 1-1:1.0: USB Mass Storage device detected scsi host0: usb-storage 1-1:1.0 scsi 0:0:0:0: Direct-Access SMI USB DISK 1100 PQ: 0 ANSI: 0 CCS sd 0:0:0:0: Attached scsi generic sg0 type 0 sd 0:0:0:0: [sda] 15730688 512-byte logical blocks: (8.05 GB/7.50 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] No Caching mode page found sd 0:0:0:0: [sda] Assuming drive cache: write through sda: sd 0:0:0:0: [sda] Attached SCSI removable disk
2）Test over Take out USB device from base board，system will output message like following：
usb 1-1: USB disconnect, device number 2
- Test results: as above "(8.05 GB/7.50 GiB)" can identify the size of U disk, indicating that the test passed.
TF Card Test
Interface properties
Interface location: P5
Interface type ：MicroSD
Test Method
1）Start test
When the power is off, insert the TF card into the interface of the TF card on the back of the baseplate before starting the system
Enter the following command:
# dmesg | grep mmc0
The system output is similar to the following information, which means the TF interface is normal:
mmc0: SDHCI controller on 2190000.usdhc [2190000.usdhc] using ADMA mmc0: host does not support reading read-only switch, assuming write-enable mmc0: new high speed SDHC card at address 1234 mmcblk0: mmc0:1234 SA32G 28.9 GiB
2）View the system's TF card equipment Enter the following command:
# ls /dev/mmcblk0*
The system will output the following information:
/dev/mmcblk0 /dev/mmcblk0p1
RGB Screen Test
Test instructions;Show that the connection of module can not be connected with wrong, avoid burning board;
- Refer to the attached picture in the screen module connection in 《Linux fast boot manual》 for the specific connection
- After starting up the development board and entering the system, the following lines of text are displayed on the screen:
Freescale i.MX Release Distro 4.1.15-2.1.0 myimxlek140/dev/tty1 imx6ek140 login:
The above display on the screen indicates that the screen is normal.
