is there a system clock in dragon board 410c?
Can you be a bit more specific? System clock is a bit unclear since it often means different things to different people. What do you want to use it for?
Actually I want date and time from dragon board is it be possible ? If yes
There certainly no real time clock meaning there is nothing to maintain date and time when the power is turned off. However it is fairly easy to add one to the I2C bus if you need it
Even without a real time clock, once you have set the time (manually, network, satellite) the OS will maintain is using the system timers for as long as the OS is running (I guess some low power states might need an RTC to reconfigure themselves on exit… but I don’t think very low power states aren’t supported for the Debian kernels anyway).
