Hi Maria,

I've been searching for a firmware design tool or something similar, but they don't offer anything. It's also disappointing that their support team won't respond to me.

I suppose we'll have to either select another codec or wait for a miracle, haha.

Thanks for your attention!

João.

Hi João,

We do not have such a guide for the CS47L63 DSP. If anyone in the DevZone community has experience, please share your findings!

Some resources you can use are

The CS47L63 driver: https://github.com/nrfconnect/sdk-mcu-drivers/tree/master/cs47l63
These sections from the CS47L63 datasheet, 4.4 DSP Firmware Control:
To use the programmable DSP, the required firmware configuration must first be loaded onto the device by writing the appropriate files to the CS47L63 register map; the firmware configuration comprises program and data memory contents.
After loading the DSP firmware, the DSP functions must be enabled using the associated control fields

Details of the DSP firmware memory registers are provided in Section 4.4.2. Note that the WISCE evaluation board control software provides support for loading the CS47L63 program and data memories. A software programming guide can be provided to assist users in developing their own software algorithms — please contact your Cirrus Logic representative for further information.

Best regards,

Maria
