Hii ,
I am trying to achieve media clock synchronization between two jacinto 6 EVM boards with ti-glsdk_dra7xx-evm_7_03_00_03 kernel image . For that I want the talker to get timestamps of the sampling clock from one node ,To achieve this I have planned of using CPTS driver for getting timestamps . In other EVM node I have to create a sampling clock with particular frequency and I have to align the rising edges of the clock from user space . My queries are as follows:
1. Whether I can achieve the synchronization of the two evm mcasp clocks?.
2. If possible How can I route the mcasp clock to CPTS? and how can I get the timestamps in user space ?.
3. I want to access the PLL used by Mcasp clock from user space. Is there any available sys calls for that purpose or I have to do any changes in the kernel source code?
