Test Environment

  • Development board model:MY-IMX6-EK140-6Y
  • Kernel version:Linux-4.1.15
  • File system:L4115-core-image-base-myimx6a7.tar.bz2

Preparation before test

1)Please connect following the path of 《Linux fast boot manual》->“Linux fast boot” -> “device connection”.

2)Please boot following the path of 《Linux fast boot manual》->“Linux fast boot” -> “device booting”.

Test item

Network inferface test

MY-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
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
  • Execute test command:
# ping -c 4 
  • Observe test result:system will output message like following:
PING ( 56 data bytes
64 bytes from seq=0 ttl=64 time=2.848 ms
64 bytes from seq=1 ttl=64 time=0.496 ms
64 bytes from seq=2 ttl=64 time=0.478 ms
64 bytes from seq=3 ttl=64 time=0.518 ms

--- 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
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.
