Bare metal example using SPI

[vix]

Is there a bare metal example for VF61 that shows how to use SPI in master mode?

I'm interested in having a frame of 24 bits; according to the VFxxx Reference Manual

SPI frames longer than 16 bits can be supported using the continuous selection format.

Is there an example that shows this feature?

Hello Vix,

You can take a look to the BareMetal examples available in the following web page, there is a QSPI driver, that you may use.

Have a nice day sir!

I looked to the QSPI example, and modified it to work with SPI0.

I enabled the clock CCM_CCGR0_CG12 and set the IOMUXC PTB19, PTB20, PTB21 and PTB22 but connecting an oscilloscope, the pins are not driven at all.

Is there any additional configuration needed?
