Hi,

 

I'm trying to make a very low power firmware for a cyw43907 board based on the dev kit design. I have some issues finding example and implementing the low power techniques.

The few example I found were only for wiced. And the templates in modustoolbox unfortunately do no use powersave.

Are there examples or doc somewhere for cyw43907 and powersave?

Thanks,

Cédric

Hi @cedric_roomz ,

There is no direct example code for CYW43907 low power mode. 

I am attaching the link for MTB low power  mode example for other modules. You can refer to the same, I think this code might be helpful to implement for CYW43907.

Hi Rakesh,

Thank you for your reply.

Can you confirm whether modustoolbox is 100% compatible with the cyw43907?

 

And when looking at cyhal_syspm_hibernate, this only supports CYHAL_SYSPM_HIBERNATE_WDT, which does seem to be a wake up source for CYW43907's hibernate according to its spec.

Thanks

Cédric

Thanks for fast response.

What are the main things which yet have to be enabled? 

Specifically for hibernate, is cyhal_syspm_hibernate compatible? Or do I need to tinker with lower layers?

Hi @cedric_roomz ,

I verified internally that currently power save mode is not supported in MTB for CYW43907.

Thanks for the feedback, this is much appreciated!

Is the qspi driver also in the pipeline? We need to be able to read/write on flash.

Hi,

As we're waiting on this to release our product, can we get a more precise estimate? And/or a way to follow progression in the pipeline?

Also, how can I know when there is an update on any of the relevant package. Is there some notification available somewhere? 

 

Thanks,

Cédric

Hi, 

Any update on the schedule? I've installed modustoolbox v3.0 and hoped it would come with the missing libraries (qspi , ...), but it did not.
