3Intro
4=====

6This default configuration will allow you to start experimenting with the
7Buildroot environment for the Banana Pi M1+. With the current configuration
8it will bring-up the board, and allow access through the serial console.
9
10How to build it
11===============
12
13Configure Buildroot:
14
15 $ make bananapi_m1_plus_defconfig
16
17Compile everything and build the SD card image:
18
19 $ make
20
21How to write the SD card
22========================
23
24Once the build process is finished you will have an image called "sdcard.img"
25in the output/images/ directory.
26
27Copy the bootable "sdcard.img" onto an SD card with "dd":
28
29 $ dd if=output/images/sdcard.img of=/dev/sdX
30
31Notes:
32 - replace 'sdX' with the actual device with your micro SD card
33 - you may need to be root to do that (use 'sudo')
34
35Insert the micro SD card in your Banana Pi M1+ and power it up. The console
36is on the debug TTL UART, 115200 8N1.
