Compile and run the button routine for the i.MX6ULL development board [Copy link]

We use the command "vi Makefile" to enter the Makefile. As shown in Figure 1:

Add the following content.


Change TARGET to "key" in line 2.
Add the GPIO and key driver header file path to the variable INCDIRS in line 14, which is the path of the files gpio.h and key.h.
Add the GPIO and key driver file path to the variable SRCDIRS in line 22, which is the path of the files gpio.c and key.c.
A partial screenshot is shown in Figure 2:

Save and exit after modification.

The linker script file remains unchanged.

Then we enter the command "make" in the terminal to compile the code.

We can use the command "ls" to see the generated key.bin file, as shown in the figure

We use the command "chmod 777 create_imx" to modify the permissions of the create_imx file.

Then use the command "./create_imx key.bin" to generate the burning file bare.imx, as shown in the figure

We copy the generated bare.imx file to the corresponding file in the mfg burning tool through SSH software. For this step, please refer to the previous burning section. Switch the dip switch to burning mode, power on and wait for the burning to complete, then switch the dip switch back to start mode and wait for the program to run normally. We can control the buzzer to sound by pressing the button.
