Introduction

This is BSP layer for Mangopi-MQ which uses T113-S3 SoC. Following preipherals are working and tested

1. TCON with RGB interface (default to 800x480)
2. CAN0
3. USB-OTG in device mode only (default to ecm, acm gadget)
4. USB-HOST
5. WiFi

Getting started

1. Clone required layers:

git clone git://git.yoctoproject.org/poky -b dunfell
cd poky/
git clone git://git.yoctoproject.org/meta-arm -b dunfell
git clone https://github.com/openembedded/meta-openembedded.git -b dunfell
git clone https://github.com/meta-qt5/meta-qt5.git -b dunfell
git clone https://github.com/ArashEM/meta-mangopi.git -b dunfell
cd ../

2. Export template configuraiton path and initialize build envrionment

export TEMPLATECONF=${TEMPLATECONF:-meta-mangopi/conf}
source poky/oe-init-build-env mangopi-mq

3. Start build process

bitbake qt5-image
bitbake -c do_populate_sdk qt5-image

4. Flash wic image into your SD card

sudo dd if=tmp/deploy/images/mangopi-mq/qt5-image-mangopi-mq.wic of=/dev/sdX

5. Enjoy :-)

View

Here is what it looks like (using 800x480 LCD)

ToDo

1. There is no driver for TPADC. So with current LCD (40pin FPC with integrated resistive touch scree) touch screen is not available (for now!)
2. Enabling tve causes issue with RGB interface. When tve was enabled, RGB interface size and referesh rate was not correct. For example enabling tve make display pipeline like this

Not to the crtc-1. But after disabling tve, I got this

I want to thanks all contributors of AWboot. Their bootloader and kernel patches are directly used in this layer.
