+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!
