Buildroot for Embest RIoTboard

==============================

​

1. Compiling buildroot

----------------------

​

make riotboard_defconfig

make

​

2. Installing buildroot

-----------------------

​

Prepare an SD-card and plug it into your card reader. Write the bootloader to

your SD-card:

​

sudo dd if=output/images/u-boot.imx of=/dev/sdX bs=1k seek=1

​

Create 1 partition on the SD-card using your favourite tool. The

partition should be big enough to hold your rootfs, for example

128MiB. Here's an example partition layout:

​

   Device Boot      Start         End      Blocks   Id  System

/dev/sdX1            2048      264191      131072   83  Linux

​

Format the SD-card partition with your favourite filesystem:

​

sudo mkfs.ext2 /dev/sdX1

​

Deploy your rootfs to the SD-card:

​

sudo mkdir /mnt/sdcard/

sudo mount /dev/sdX1 /mnt/sdcard/

sudo tar xf output/images/rootfs.tar -C /mnt/sdcard/

sudo umount /dev/sdX1

​

3. Running buildroot

--------------------

​

Position the board so you can read the label "RIoTboard" on the right side of

SW1 DIP switches. Configure the SW1 swiches like this:

​

10100101 (1 means ON position, 0 means OFF position)

​

Now plug your prepared SD-card in slot J6. Connect a serial console (115200, 8,

N, 1) to header J18. Connect a 5V/1A power supply to the board and enjoy your

new toy.
