We will have the warp_0x01 ultra small form factor application processor on display at the 2017 Embedded Linux Conference in Portland Oregon, February 21-23 2017.
We’ve put together various HOWTO videos that should help you get to the serial console on different OSes with different configurations, (Warp standalone or via the Interposer board). We’ve covered Linux, Mac and Windows.
You can find the bundle of videos over on our YouTube channel. Otherwise, here are direct links for each:
Serial Console, standalone Warp on Linux
Serial Console, standalone Warp on MacOS
Serial Console on Warp via Interposer on MacOS
To get warp connected to the Internet quickly, the Yocto Linux release for warp conveniently has a shell script: /home/root/wifi_connect, which enables you to get connected to a nearby WiFi network.
You may have to set the execute bit on this file to be able to run it as some earlier releases of Yocto Linux for Warp did not have execute permissions on the file. You can run:
chmod 750 /home/root/wifi_connect
to ensure that this is set correctly.
The wifi_connect script takes two arguments as input.
Argument #1: WIFI-NET
Argument #2: PASSWORD
For example:
/home/root/wifi_connect Starbucks pass1234
If you’d like to watch a YouTube video on this topic, see here: Warp – Yocto Linux – Connect to a WiFi Network
If you do not see the wifi_connect script under /home/root of your Warp, you can make the wifi_connect script using vi and the command line to include the following contents:
#!/bin/sh
ip link set wlan0 up
iw dev wlan0 scan
mkdir -p /etc/wpa_supplicant/
wpa_passphrase $1 $2 >/etc/wpa_supplicant/file.conf
wpa_supplicant -B -iwlan0 -Dnl80211 -c/etc/wpa_supplicant/file.conf
iw dev wlan0 link
udhcpc -i wlan0
In this video, we show how to properly power-on, boot Warp via the Interposer, and log in at the serial console on a Mac using minicom. See the video in this post to learn more.
The Warp does have a best practice to be connected and disconnected from the Interposer board. See the video in this post to learn more.
