The default clock rate would be something "around" 32 kHz, but not very accurate. Meanwhile the WiFi module would have very specific requirements on frequency and accuracy of this clock. The WiFi part doesn't seem to care that much, but the Bluetooth part cares very much. It doesn't work or it would seem to work but you don't get anything off the radio if the frequency is off (as in off-frequency). > > > > Signed-off-by: Jagan Teki <jagan@xxxxxxxxxxxx> > > --- > > Note: > > - chip detected, but failed to connect > > [ 129.084504] brcmfmac: brcmf_sdio_hostmail: mailbox indicates firmware halted > > [ 135.906409] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout > > This got fixed. Will send next version. Could you wait until I get my RTC changes out? I also have some Bluetooth patches for AP621x, which is what started all this RTC work, which you might find interesting.
