Banana Pi M1+
Intro
=====
This default configuration will allow you to start experimenting with the
Buildroot environment for the Banana Pi M1+. With the current configuration
it will bring-up the board, and allow access through the serial console.
How to build it
===============
Configure Buildroot:
$ make bananapi_m1_plus_defconfig
Compile everything and build the SD card image:
$ make
How to write the SD card
========================
Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ dd if=output/images/sdcard.img of=/dev/sdX
Notes:
- replace 'sdX' with the actual device with your micro SD card
- you may need to be root to do that (use 'sudo')
Insert the micro SD card in your Banana Pi M1+ and power it up. The console
is on the debug TTL UART, 115200 8N1.
Ethernet
==========
# udhcpc -i eth0
Wifi
==========
# wpa_passphrase YOUR_SSID >> /etc/wpa_supplicant.conf
(enter the wifi password and press enter)
# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B
# udhcpc -i wlan0
Note:
- replace 'YOUR_SSID' with the actual SSID from your access point
Audio
==========
For this example you need package alsa-utils.
Connect a headphone to the 3.5mm jack (TRRS). Note, that the Banana Pi M1+
has an on-board microphone, too.
