==NVME disk==
A NVME disk is recoginzed automatically when installed. Normal device position in linux is
/dev/nvme0n1

==Audio==
use <code>speaker-test</code> to test speaker with white noise.

==Canbus==
We have 2 canbus onboard. First run:

ip link set can0 type can bitrate 125000

then run:
ifconfig can0 up

=== Send simple test packet ===

The socket-CAN tools include the cansend utility:

<pre>
cansend <device> <can_frame>
</pre>

where the device is the network interface name, typically can0, and a CAN frame is in the format:

<pre>
<can_id>#{R|data}
</pre>

with the can_id having 3 (SFF) or 8 (EFF) hex chars. and data in the format of zero to eight 8-bit hex-values that can optionally be separated by a period ('.') or use R for remote transmission request.

To send a CAN data frame message, with a can_id arbitration field value of 0x5A1 and a data field value 0x1122334455667788:

<pre>
cansend can0 5A1#11.22.33.44.55.66.77.88
</pre>

=== Dump received packets ===

The socket-CAN tools include the candump utility, which dumps all messages being exchanged on the CAN bus. To run candump, just specify the CAN interface:

<pre>
candump can0
</pre>

If a device on the CAN bus sends a packet with ID 0x456 and data 0x122345, the output would be

<pre>
# candump can0
can0 456 [3] 12 23 45
</pre>

<pre>
cansend can0 5A1#11.22.33.44.55.66.77.88
</pre>

creates the following cumulative candump output

<pre>
# candump can0
can0 456 [3] 12 23 45
can0 5A1 [8] 11 22 33 44 55 66 77 88
</pre>

=== CAN protocol stack information ===

The CAN protocol implementation version:

cat /proc/net/can/version

The CAN bus statistics:

cat /proc/net/can/stats

==USB/USB3.0==
