MIMXRT1060-EVK: Peripherals setting

[kenji]

Hi All.

I want to drive BLDC motor using TI's motor driver.
And TI's motor driver needs to setup via SPI.

But MIMXRT1060-EVK's Arduino interface, SPI and PWM use the same pin. So I can't drive the motor driver as default board connection.

Therefore, I would like to remove the resistance of the boot mode setting and output the PWM2 signal. Someone knows if there is any problem?

I’ｍ using "evkmimxrt1060_mc_pmsm" sample demo code, and on it,  it looks not read the boot mode pins.

I want to know the effect in case remove the resistance of the boot mode pin.

Hi @kenji 

    BOOT_MODE pin will determine your boot mode during the reset, so I don't recommend to remove the BOOT_MODE pin pull up or pull down, it will influence the boot mode after you do the reset.

    About the J24 SPI and the PWM conflict, please check the RT1060 reference manual, you can find:

LPSPI and FLEXPWM has a lot of pins, you can select other pins which is not conflict, not just use J24 pins.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Best Regards,
