Polyhex Debix Model A
=====================
DEBIX Model A is an industrial grade single board computer
powered by NXP i.MX 8M Plus applications processor
https://www.debix.io/hardware/model-a.html
User Manual: [1]
How to build it
===============
Configure buildroot:
$ make polyhex_debix_model_a_defconfig
Change settings to fit your needs (optional):
$ make menuconfig
Compile everything and build the rootfs image:
$ make
Result of the build
===================
After building, the output/images directory contains:

Flashing the SD card image
==========================
To install the image on a SDCard simply copy sdcard.img to the storage (e.g. SD, eMMC)
$ sudo dd if=output/images/sdcard.img of=<your-sd-device>
Booting the board
=================
To boot your newly created system:
- insert the SD card in the SD slot of the board;
- if you use a Debix I/O daughter card, follow the instructions provided
in [2], section 3.1 for the hardware connection between the main board
and the I/O daughter card. Then, put a micro USB cable into the I/0 daughter card
Debug USB Port and connect using a terminal emulator at 115200 bps, 8n1;
- if you do not use a Debix I/O daughter card, connect a USB-to-TTL serial cable to
the 40-pin header (J2) on the main board, the following way:
USB-to-TTL cable GND pin to J2 pin 05
USB-to-TTL cable TX pin to J2 pin 09
USB-to-TTL cable RX pin to J2 pin 11
connect using a terminal emulator at 115200 bps, 8n1;
- power on the board.
Enjoy!
