My target is to communicate the two Beagle bone Black via CAN bus. I have to code in C language.
As there are two clocks: Interface clock and Functional clock in the PRCM module. And in functional clock there are various registers to enable the CLKCTRL pins for the particular module like CM_PER_GPIO1_CLKCTRL, CM_PER_GPIO2_CLKCTRL, CM_PER_DCAN1_CLKCTRL etc.
in the User Manual, Interface clock at 100 MHz and Functional clock at 26 MHz given. How can i set these frequency ?
How to set the basic clock of the Beagle bone Black ? Is there any calculation to set the clock ?
Please advise, thanks in advance
