Elemental operations of iMX6 TinyRex Development board ports in Ultra configuration are shown on this page. For more detailed information such as HDMI input interface or Wireless operation refer to the dedicated Peripheral sections.
Prerequisites
Hardware
- DC power supply (5V 2A)
- iMX6 TinyRex Module Ultra
- iMX6 TinyRex Baseboard
Peripherals and Accessories
- 1x FullHD monitor with Audio output
- 1x HD signal generator
- 1x MicroSD card
- 1x MiniPCIe WiFi card
- 1x RPi camera module
- 1x SATA HDD drive
- 2x USB FLASH drive
Cables
- Ethernet cable
- HDMI cable
- Micro HDMI cable
- Micro USB cable
- USB to UART cable
User button
Input: Press the USER button
Output: Button events 1 and 0 are generated
root@imx6-tinyrexultra:~# evtest /dev/input/by-path/platform-gpio-keys*-event
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x1 product 0x1 version 0x100pio-keys.16-event .
Input device name: "gpio-keys.16"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 116 (KEY_POWER)
Properties:
Testing ... (interrupt to exit)
Event: time 1453240251.571826, type 1 (EV_KEY), code 116 (KEY_POWER), value 1
Event: time 1453240251.571826, -------------- EV_SYN ------------
Event: time 1453240251.711820, type 1 (EV_KEY), code 116 (KEY_POWER), value 0
Event: time 1453240251.711820, -------------- EV_SYN ------------
Reset button
Input: Press the RESET button
Output: Module will execute bootloader immediately with "Reset cause: POR"
Note: Module should never freeze or hang after the reset button was pressed. Testing the operations 10 times gives a reliable result

CAN
Input: None
Output: Device driver is available

link/can
Note: Enhanced testing can be performed with a pair of iMX6 TinyRex Development boards and a couple of dedicated CAN evaluation modules
Board 1 (receiver) commands and outputs:

CSI
Input: Connect RPi camera module into CSI interface and check if it is detected on I2C bus
Output: I2C address 0x36 is occupied and under use
