Contents
Preconditions
- PC workstation
- CM-FX6 evaluation kit properly connected
- SD-Card with minimal capacity of 2GB, which will serve as the boot source
Creating a bootable SD-Card
- Download compressed SD-Card image.
- Ensure integrity of the downloaded file by testing its MD5 summary.
- Unzip the file in order to get dd image.
- Copy the bootable image to the SD-Card following the instructions provided for selection of operating systems.
- On Linux, the instructions below may may be used instead:
# dd if=cmfx6-android.img of=/dev/sdc
Boot
- Insert the bootable SD-Card into P6 SD-Card slot.
- Power on.
- Within 3 seconds the device should start booting into Android.
- Within 60 seconds the HDMI display should start showing signs of life.
Advanced boot
By default CM-FX6 uses HDMI display with 1080p resolution.
This can be changed by providing alternate boot arguments to the Android/Linux kernel.
- Connect to the serial console as explained in the Development section.
- Press ENTER to stop the countdown.
setenv videomode video=mxcfb0:dev=ldb,if=RGB24,1280x720M@60 fbmem=28M # DVI display with 720p resolution setenv videomode video=mxcfb0:dev=hdmi,if=RGB32,1920x1080M@60 fbmem=48M # default video mode setenv videomode video=mxcfb0:dev=lcd,if=RGB666,SCF04-WVGA # LCD display connected P50 LCD connector
- Type in boot to proceed to kernel boot overriding default video mode.
Normal operation
- If the CM-FX6 module went to sleep, it can be woken up by a short press on ON/OFF button on the base board.
- Additional press on ON/OFF button will send the device back to sleep.
- Pressing and holding the ON/OFF button for more than 5 seconds, will unconditionally power the module down. This operation is pretty much equivalent to unplugging the power supply, so it should really be considered the last resort.
- Yet another press on ON/OFF button will bring the power back.
- Graceful shutdown
- Due to specifics of i.MX6 SoC hardware, the ON/OFF button cannot be used to bring up the Android Power off menu.
- CM-FX6 pre-configures GPIO 29 (P18, pin 2 on SB-FX6 base board) as GPIO Power Button. As GPIO 29 has an internal pull-up resistor, it can be momentarily connected to the ground to produce a 'power button press'. Short press will behave identically to short press on ON/OFF button, whereas long press will bring up the Power off menu allowing graceful shutdown.
