Overview#
The romapi_lpspi example shows how to use ROMAPI to operate program SPI flash:
The project is a simple demonstration program of the SDK FLASIAP driver. It erases and programs a portion of on-board SPI flash memory. A message is printed on the UART terminal as various operations on SPI flash memory are performed.
Hardware requirements#
Type-C USB cable
MCXW72-LOC Board
Personal Computer
Board settings#
This Example project does not call for any special hardware configurations. Although not required, the recommendation is to leave the development board’s jumper settings and configurations in default state when running this example.
Prepare the Demo#
Connect a USB cable between the host PC and the LOC board J3.
Open a serial terminal with these settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the example.
Running the demo#
These instructions are displayed/shown on the terminal window:
ROM API LPSPI Example Start
Initializing LPSPI flash
LPSPI flash Information:
LPSPI flash base address: 0, Hex: (0x0)
LPSPI flash page size: 256 B
LPSPI flash total size: 8192 KB, Hex: (0x800000)
Erase a sector of LPSPI flash
Successfully erased sector 0x7ff000 -> 0x800000
Program a buffer to a page of LPSPI flash
Successfully programmed and verified location LPSPI flash 0x7ff000 -> 0x7ff200
End of LPSPI flash Example
And you will find the flash has been programed.
