Revision as of 08:07, 13 March 2021
Elemental operations of iMX6 TinyRex Development kit interfaces in Ultra configuration are shown on this page. For more specified information such as HDMI Input port 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 HDMI signal generator (such as PC with HDMI interface or GoPro camera)
- 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
U-Boot 2014.10 (Jan 19 2016 - 20:37:48) CPU: Freescale i.MX6SOLO rev1.1 at 792 MHz Reset cause: POR Board: MX6 TinyRex - basic I2C: ready DRAM: 512 MiB MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2 *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: FEC [PRIME] Hit any key to stop autoboot: 0
CAN
Input: None
Output: Device driver is available
root@imx6-tinyrexultra:~# ip addr show dev can0
2: can0: <NOARP,ECHO> mtu 16 qdisc noop state DOWN group default qlen 10
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:
