I have built the example by moving mcspi_performance_8bit.c to the same location as loopback.c, replacing loopback.c with 8bit.c in make file and making sure the main function in main.c calls mcspi_performance_main(). The example builds without errors. When run it does not complete, does not show the debug messages at the end and does not produce correct output on logic analyzer

Below is output on uart port. Example halts here and does not produce final debugP_log

Hi Zorah,

I am unsure if this example has been fully tested on this device. I will speak to the dev team about this.

Do you simply want an example on how to use MCSPI? What do you wish to use MCSPI for?
Thanks,

Neehar

yes I want to verify on a logic analyzer that the spi is configured correctly. I want to use the device as a host to communicate and configure a radar device

Hi Zorah,

Ok thanks for this information. I am still waiting to hear back if this example has been validated and I will get back to you.
Thanks,

Hi Zorah,

This example has not been validated for SDK 9.2 or on this device. There is no plan to have it ready by SDK 10.0 release so I would use the loopback example as a reference for any development you require.
Thanks,

Neehar
