Hi,
I am using the Inventek's variant of BCM43341 wifi/ble/nfc module.
I wanted to know, how should I go about allocating space on the 4KB SRAM that is backed up using VBAT, even the module is powered down (VDD).
I wish to save some application context during sleep in this 4KB space and when powered on, I should be able to recover whatever was saved.
Is there any API for allocating data to this specific portion of SRAM?
thanks!
Regards,
Manish

Currently no. There is no standard memory map for this. You will have to create a custom map. And then use that to store the data.

Is there an example that I can repurpose to create the memory map for storing into the battery backup SRAM? It does not matter which platform it may be for.
thanks!

We have not done this for any platform. But you can check the BCM9WCD1AUDIO platform in SDK 3.5.2 which has a mapping for special RAM in the STM417
You can do something similar
