Get some general information (Hardware description, installation of openSUSE, etc.) on HCL:PandaBoard.
You have to configure inputs and outputs. You can either:
- restore values from a file
wget http://guillaume.gardet.free.fr/openSUSE/pandaboard-alsa.conf alsactl -f pandaboardboard-alsa.conf restore
- OR, configure it manually with alsamixer: (switch Headset Left Playback and Headset Right Playback from Off to HS DAC and set Headset level to 100.)
Then you can try to play some files:
And to record some sound:
In order to test CPU freq capabilities, please download this script:
And execute it. You should see something like:
Automatic Voltage Scaling (AVS) (formerly known as Smartreflex)
AVS is not easily testable but is enabled in the kernel.
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:
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:
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.
On a pandaboard rev. A3, , with kernel 3.11.10-2-default, we get 95 Mb/s.
If you boot on your SD card, then SD/MMC works! ;)
Plug a serial cable (or serial/usb) between the board and your computer. Start minicom:
And switch on the board. You should see something starting with:
U-Boot SPL 2013.04 (Jan 08 2014 - 14:33:37)
OMAP4430 ES2.2 OMAP SD/MMC: 0 U-Boot 2013.04 (Jan 08 2014 - 14:33:37)
Plug an USB stick and mount it:
mount /dev/sda1 /mnt
And see what is on your stick:
