RK3229 RTC support


does the Rockchip RK3229 SoC contain a RTC?

sudo hwclock -r …

… takes some seconds to complete, but returns without an result - I’d assume there is no RTC, right?

Thank you for helping

Hi there,

There is no RTC inside of RK3299, but there is a RTC inside of RK805. please refer to RK805 datasheet. <LINK_TEXT text=“http://files.pine64.org/doc/rock64/Rock … 160921.pdf”>http://files.pine64.org/doc/rock64/Rockchip_RK805_Datasheet_V1.1 20160921.pdf</LINK_TEXT>
