DSPI slave example on FRDM-K66F like board

mdecandia — Wed, 19 Oct 2022 09:28:44 GMT

Hi all,

we are testing the dspi samples from SDK and they are not working on a board derived from FRDM-K66F. There are few changes (clock frequencies, pinmuxing) but they should not impact SPI slave functionality.

Do they should work on this evb?

Hello @mdecandia,

Could you please help us with more information related with your issue? Did you receive an error while debugging or your problem is that the communication is not working? Could you tell us which other changes did you make in your board? What clock frequency are you working with? What pins do you configure for the DSPI you are working with? Which SDK example and version are you using?

Best regards, Raul.

Hi @RaRo,

thanks for your feedback. In the meanwhile we have found the issue: we were using the SPI0_PCS5 as chip select pin that cannot be used as SPI slave.

Kind regards.

Michele
