| 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. |
| |
| # amixer cset name='Power Amplifier DAC Playback Switch' on |
| # amixer cset name='Power Amplifier Mute Switch' on |
| # amixer cset name='Power Amplifier Volume' 42 |
