SDK 2.9.0 Missing LPSPI Driver Examples for MIMX8Q5XXXFZ

[AmoghOwlstone]

Hello NXP Community,

In the documentation for the 2.9.0 tagged SDK here: https://mcuxpresso.nxp.com/api_doc/dev/2127/a00032.html

this mentions that examples for the LPSPI driver are located under the boards folder <SDK_ROOT>/boards/<BOARD>/driver_examples/lpspi

However, this folder does not exist. I have checked newer versions of the SDK on github and these do not have driver examples for the board I wish to use either.

1. Where can I find the potentially missing LPSPI driver examples as stated in the documentation linked above?

2. Was this support removed?

Thanks in advance!

Hello,

Could you try downloading the board package?
I have just downloaded the package and found the LPSPI driver examples there, so please try again.

Hi Aldo,

Thanks for your reply.

I'm afraid I followed the link and built the SDK (for linux): https://mcuxpresso.nxp.com/en/dashboard?uvid=482182&to_vault=true

But still I cannot see any lpspi driver examples. Please see the attachment.

If you could provide an SDK for SDK_2.9.0_MEK-MIMX8QX that has the examples that would help a lot.

Many thanks,

Amogh

Hello,

Sorry for the confusion I made a mistake I thought you were looking for the i.MX8QM not the i.MX8X, please note that the i.MX8X Cortex-M4 has no access to the LPSPI since this module is part of the ADMA (Audio DMA) subsystem this is why is not present in the driver examples.

Best regards,
Aldo.

Hello Aldo,

Thank you for the explanation, as you mention I intend to use the LPSPI through the ADMA subsystem.

Is there an SDK or equivalent documentation that does contain driver examples for LPSPI for the i.MX8 family that I can use as reference to prove out this subsystem and write some tests?

Thanks,

Amogh

Hello,

We have driver files available, this include LPSPI, in the following route:
<SDK installation path>devices\MIMX8QX6\drivers

Best regards,
Aldo.

Hi Aldo,
Thanks I understand. But just to clarify there are no examples for this even though there is a valid use case of LPSPI on this SoM?

Hello,

Indeed this seems to be the case.

Best regards,
Aldo.
