Setting up the system
The following will describe how to run the pre-loaded Linux image on the MCIMX91-EVK (i.MX 91).
- Confirm boot switches
The boot switches should be set to boot from “eMMC”, SW1301[4-1] (Figure 1) are used for boot, See table below:BOOT Device SW1301[1-4] eMMC/uSDHC1 0000 Note: 1 = ON 0 = OFF
- Connect USB debug cable
Connect the UART cable into the port JP1401 (Figure 1). Connect the other end of the cable to a PC acting as a host terminal.
UART connections will appear on the PC, The third port will be used as A55 core system debugging.
Open the terminal window (i.e., Hyper Terminal or Tera Term), choose the right COM port number and apply the following configuration.
• Baud rate: 115200bps
• Data bits: 8
• Parity: None
• Stop bits: 1 - Connect parallel panel display
Plug the parallel LCD panel (T050RDH03-HC) into J1001 2×20 PIN header. - Connect mouse
Connect the mouse to the USB2 C port connector J302 through USB C OTG cable. - Connect power supply
Connect the USB C PD power supply to J301, then power up the board by SW301 switch.
- Board boot up
As the board boots up, you will see 4 penguins appear in the upper left-hand corner of the monitor, and then you will see the Linux terminal Icon on the top left and timer on right top corner . Congratulations, you are up and running.
Run “Go Point for i.MX Applications Processors” application to explore the preinstalled demos. The NXP Logo is displayed on the top left-hand corner of screen, start the demo launcher by clicking this logo. Refer to user guide for details: https://www.nxp.com/webapp/Download?colCode=GPNTUG.vz
Additional information
Boot Switches
SW1301[1-4] is the boot configuration switch, the default boot device is eMMC/uSDHC1, as shown in Table 4. If you want to try other boot devices, you need to change the boot switches to corresponding values as listed in Table 4.
Note: 1 = ON 0 = OFF
