iMX8QuadXPlus Cortex M4 (audio handling) + HiFi4 (audio processing), without A35 core(without Linux)

Ferromagnetic — Wed, 14 Dec 2022 11:50:11 GMT

Hi,

I have a question how to deploy dsp binary and debugging hifi4 (using JLink debugger) core connected with cortex M4 core without using A35 cores (without Linux). I want to omit A35 cores and proceed development only on M4 core and hifi4 dsp. I have no found information in docs on nxp and tensilica sites. There are only examples how to run hifi4 from Linux on A35 cores side. I think that is possible but how to start it, please help me with some advices/examples.

Thanks in advance!

Dear Dominik Kuzniar,

As DSP on iMX8QuadXPlus we have the Sound Open Firmware, which is supported in the BSP for i.MX. So, by default it is prepared to work on A35 core with Linux. You can find more details about it in:

Sound Open Firmware

Best regards.
