Software/driver access to TSF on CYW43455 (Raspberry PI 3B)

[DaGr_4359036]

It seems that the Hardware TSF implemented by WiFi controllers is a useful source of a synchronized time datum across the devices connected to a single WiFi network.

I see that this question hardware timestamping  about accessing TSF in an earlier WiFi chip received the negative response "Synchronizing TSF with host MCU is not supported on Wiced."

I would like to know if - and how - the CYW43455 TSF can be accessed by host software or driver (typical host might be RPI3B).

Thanks!

If you have provision to run wl utility in your host, you can try using wl tsf for getting the TSF register.
