qspi_edma_transfer#
Overview#
The qspi_edma example shows how to use qspi driver with EDMA:
In this example, qspi will send data and operate the external flash connected with QSPI. Some simple flash command will be executed, such as Write Enable, Erase sector, Program page. Example will first erase the sector and programe a page into the flash, at last check if the data in flash is correct.
Supported Boards#
EVK-MCIMX7ULP
Hardware requirements
Micro USB cable
MCIMX7ULP-EVK board
J-Link Debug Probe
5V power supply
Personal Computer
Board settings
The example is uses QSPI0. The module uses PTB8, PTB15 ~PTB19 pins. No special jumper needs to be connected.
Please note this application can’t support running with Linux BSP!
Please note that this application must be built with ram link file! Because if running the application in QSPI flash in place, the QSPI flash erase/program feature of the application might affect the instruction fetch. If QSPI execution in place(XIP) is really needed, please make sure the flash erase/program operation must be handled by RAM function and disable all interrupts to avoid jumping into interrupt handler in flash area during flash updating.
Prepare the Demo
Connect 5V power supply and J-Link Debug Probe to the board, switch SW1 to power on the board.
Connect a micro USB cable between the host PC and the J6 USB port on the target board.
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.
Either press the reset button on your board or launch the debugger in your IDE to begin running the example.
NOTE: Don’t build this example with flash linkage file since this example need to modify QSPI controller, so program itself cannot be run in QSPI flash.
