SPI communication on MCIMX8M-EVKB

neo2 — Mon, 24 Jan 2022 11:26:26 GMT

Dear NXP

I have an MCIMX8M-EVKB board.

Is there a location where SPI is available to connect to another NXP board?

The only header I see is J801 but that only seems to have a I2C interface.

Or is it is not possible to connect the MCIMX8M board as there are no spare SPI headers or points to connect the 4 wires?

Regards

Lee.

Replying to my own question.

Based on what I seen on the schematic I don't see a suitable point SPI interfaces

1. the ECSPI interfaces are being used up by the board itself for it's own chips

2. the QSPI interface is just for Flash rather than a generic SPI. I don't see MOSI and MISO on that interface.

I'll probably used the Ethernet interface instead.

Hi Neo,

No, this board does not have an SPI port. yes you could the ethernet.

Best Regards.
