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 how an
example of such 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 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.
