queued_spi_polling_flash#
Overview#
The spi_interrupt example shows how to communicate with mx25l flash using spi polling functional API.
Supported Boards#
MC56F80000-EVK
Hardware requirements
Micro USB cable
MC56F80000-EVK board
Personal Computer
Board hardware common setting
Power setting:
Connect J8 pin2 and pin3 Connect J6 pin1 and pin2 Connect J5 pin1 and pin2
Reset pin setting:
Connect J11 pin2 and pin3
Debugger setting:
Connect J13 pin 1-2, 3-4, 5-6, 7-8
Board settings
No special settings are required.
Prepare the Demo
Connect USB cable between the host PC and the J12 USB port on the target board. It setups Multilink and COM port in PC device manager.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board with Multilink debug configuration.
Launch the debugger in your IDE to begin running the demo.
Running the demo
The log below shows the output of the hello world demo in the terminal window:
*****app*start*****
Flash at 0x0 of size 64 B has message 'ahoj'
Write new message (max 63 chars) to flash:
hello
message is: 'hello'
Write succeed, please restart the board to see the written message
*****app*end*****
note:
If the EVK board runs this example for the first time, the message on terminal will be “Flash at 0x0 of size 64 B is empty “
‘ahoj’ is the content in spi flash, written by this driver example previous execution
‘hello’ is input through terminal
MC56F81000-EVK
Hardware requirements
2 x Micro USB cable
MC56F81000-EVK board
Personal Computer
Board hardware common setting
Power setting:
Connect J8 pin2 and pin3 Connect J5 pin1 and pin2 Connect J6 pin1 and pin2
Onboard PnE U-MultiLink debugger setting:
Connet J11 pin2 and pin3 Connect J13 pin 1-2, 3-4, 5-6, 7-8, to setup onboard debugger PnE U-MultiLink. Note: when use external debugger(connected to J10), leave all J13 pins open.
Board settings
No special settings are required.
Prepare the Demo
Connect USB cable between the host PC and the USB(J26) port on the target board to setup USB to UART bridge.
Connect USB cable between the host PC and the USB(J12) port on the target baord to setup mulitlink debugger.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board with PnE U-MultiLink debug configuration.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo. Please be noted default FCF(flash configuration field) makes the MCU boot from flash.

MC56F83000-EVK
Hardware requirements
Micro USB cable
MC56F83000-EVK board
Personal Computer
Board hardware common setting
Power setting:
Connect J19 pin2 and pin3 Connect J12 pin1 and pin2 Connect J13 pin1 and pin2 Connect J15 pin1 and pin2 Connect J16 pin2 and pin3 Connect J17 pin1 and pin2
Onboard OSJTAG debugger setting:
Leave J5 open Leave J6 open Note: J6 is only used(connected) when firmware update for onboard debugger OSJTAG. Connect J11 pin 1-2, 3-4, 5-6, 7-8, to setup onboard debugger OSJTAG. Note: when use external debugger(connected to J10), leave all J11 pins open.
Board settings
No special settings are required.
Prepare the Demo
Connect USB cable between the host PC and the JM60 USB(J8) port on the target board. It setups OSJTAG and COM port in PC device manager.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board with OSJTAG debug configuration.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo. Please be noted that default FCF(flash configuration field) setting makes MCU boot from bootloader. So after reset button press, it will wait 5s(wait in bootloader) to run the application code.
