openSUSE:SABRE Lite

General information

Get some general information (Hardware description, installation of openSUSE, etc.) on HCL:SABRE_Lite.

Tests

audio in/out

You can configure it manually with alsamixer: (by default output volume is low)

 alsamixer

Then you can try to play some files:

 aplay test.wav

And to record some sound:

 arecord test_input.wav

CPU freq

In order to test CPU freq capabilities, please download this script:

 http://guillaume.gardet.free.fr/openSUSE/cputest.sh

And execute it. You should see something like:

 Available freqs: 396000 792000 996000 
 bogomips@ boot:
 BogoMIPS        : 3.00
 BogoMIPS        : 3.00
 BogoMIPS        : 3.00
 BogoMIPS        : 3.00
 Boot scaling frequency =396000
 TESTING for 1 second(s) at 396000
 current scaling frequency(for 396000) = 396000
 bogomips@ frequency 396000:
 BogoMIPS        : 3.00
 BogoMIPS        : 3.00
 BogoMIPS        : 3.00
 BogoMIPS        : 3.00
 TESTING for 1 second(s) at 792000
 current scaling frequency(for 792000) = 792000
 bogomips@ frequency 792000:
 BogoMIPS        : 6.00
 BogoMIPS        : 6.00
 BogoMIPS        : 6.00
 BogoMIPS        : 6.00
 TESTING for 1 second(s) at 996000
 current scaling frequency(for 996000) = 996000
 bogomips@ frequency 996000:
 BogoMIPS        : 7.54
 BogoMIPS        : 7.54
 BogoMIPS        : 7.54
 BogoMIPS        : 7.54

Automatic Voltage Scaling (AVS) (formerly known as Smartreflex)

Not sure about iMX AVS status.

Ethernet

You can test functionality. Plug a cable on a network where a DHCP server and a router are running. Wait a while and then see if you have an IP address:

 ip addr show

Then try to ping something on the network:

 ping 192.168.1.254
 ping www.google.fr

You can also test the performances with iperf. Install iperf on a computer and on the board and run on one side the iperf server:

 iperf -s

and on the other side, the iperf client:

 iperf -c <ip_addr_of_iperf_server>

then you can invert the iperf server and client and rerun the tests.

With kernel 3.11.10-2-default, we get 695 Mb/s (download) and 240 Mb/s (upload).

SD/MMC

If you boot on your SD card, then SD/MMC works! ;)

UART (debug)

Plug a serial cable (or serial/usb) between the board and your computer. Start minicom:

 sudo minicom

And switch on the board. You should see something starting with:

 U-Boot 2009.08 (Aug 16 2012 - 10:06:42)
 
 CPU:   Freescale i.MX 6 family 0.0V at 792 MHz
 Temperature:   18 C, calibration data 0x56c4b57d
 mx6q pll1: 792MHz
 mx6q pll2: 528MHz
 mx6q pll3: 480MHz
 mx6q pll8: 50MHz

USB hosts

Plug an USB stick and mount it:

 mount /dev/sda1 /mnt

And see what is on your stick:

 ls /mnt

Unmount it:

 umount /mnt
