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.
