DM365 internal voice codec and RTC

Robin Iddon

Has anyone got working driver code for the internal voice codec on the DM365 (CONFIG_SND_SOC_CQ0093VC)? The code shipped in beta LSP 02_10_00_11 seems to be a work in progress. I've tried fiddling with it a bit, but I'd rather not do this myself if someone has more recent code available.

I havn't had a chance to look at it in detail, but the DM365 RTC driver (CONFIG_RTC_DRV_DAVINCI_DM365) seems to be unreliable too. Perhaps this is why it wasn't in the defconfig for the DM365-EVM.

    The DM365 software that is out there is still beta, so I would expect it to improve over time as it is being actively developed, for better or worse what you have today is probably the best that is available, I would suggest keeping an eye on the EVM updates site for new releases as they are made available.

    Support for both internal voice codec and RTC is available in the DM365 LSP GA release (LSP 02_10_00_14).  The release has been distributed internally for integration into the DVSDK 2.10 GA candidate and should be available on the sds download site within the next few days.

    Hi Gary,

    I measured voltage on TP18 at the Spectrum digital DM365 EVM Ver.C.
    The voltage is abnormal, I get 2.8V on TP18 when I plugged in the power adapter. But VDD12_PRTCSS is normal 1.167V. 
    When the PRTCSS is powered with backup Lithium-Battery, I didn't measure 1.2V and 1.8V on TP19 and TP18. 

    You said that internal RTC is available in the DM365 LSP 02_10_00_14 release. 
    I tried it on the EVM, but  it didn't work out.

    Thanks in advance for any info you can offer.

    Martin
