Chapter 2
Hardware settings
This chapter describes how to set up the hardware of the evaulation board. The MCU peripherals' setup is described later on.
The IEC60730B library example for the I.MX8mx family supports the following development boards:
• EVKmimx8mm
• EVKmimx8mn
To run the IEC60730B example application, it is neccessary to make some hardware settings. For the default configuration of your
development board, see the corresponding board's user manual at
.
2.1 EVK-MIMX8MM (Mini)
The hardware requirements are as follows:
• i.MX8M Mini development board (EVK-MIMX8MM)
• J-Link debug probe
• USB-C cable (12-V power supply)
• USB-C cable (download to ROM memory)
• Micro USB cable (debug print)
Debugger:
The default debugger in the example project is set to J-Link.
FreeMASTER
FreeMASTER communication is used via an external J-Link plugin.
The hardware settings are as follows:
1. Connect the 12-V power supply (J302 USB port) and the J-Link debug probe to the board and switch the SW101 switch to
power on the board.
2. Connect a USB-C cable between the host PC and the J301 USB port (this port allows downloading to the ROM memory).
3. If a debug print is needed, connect a micro USB cable between the host PC and the J901 USB port on the target board.
Then open the serial terminal with the following settings:
• 115200 baud rate
• 8 data bits
• No parity
• One stop bit
• No flow control
4. Set the SW1101 switch to value "01110010" and SW1102 to value "00101010" to boot from the eMMC.
