sai_sdma_transfer example can't run with linux BSP?

mwilliams — Fri, 07 Oct 2022 13:57:56 GMT

I notice that the readme.txt file associated with the sai_sdma_transfer example for the IMX8MMEVK states that the example cannot be run with the linux BSP. My question is why? I confess that I have not tried to find out the details on my own yet, but I thought that disabling the SAI on the linux side DT would do. Is this a limitation that can be removed by any means of customization of either the example or the Linux side?

Hello,

Yes, this kind of examples it may need more than just disabling the same peripheral in linux dts, disabling clocks and maybe reserving a part of memory.

In this particular case you may refer to the sai_low_power_audio example which should be interesting for you. It is inside the SDK package <SDK installation path>\boards\evkmimx8mn\demo_apps

Best regards,
Aldo.

Hi AldoG,

Thanks for your reply. I have been able to run the SDMA transfer example and I will study the other example you point out.

Best regards,

Mike
