How to use BD71847 internal RTC with IMX8M-MINI controller

Hi,

I do have IMX8M-MINI controller interfaced with BD71847 power management IC using yocto setup.

Can you provide me the solution on how to use internal RTC of BD71847 with IMX8M-mini controller.

Thanks.

Hi,

To use the internal RTC of BD71847 with the IMX8M-MINI controller, you will need to interface the two using the I2C protocol. The BD71847 power management IC has an inbuilt RTC which can be accessed via I2C.

Assuming you have already set up the I2C communication between the IMX8M-MINI and the BD71847, you can access the RTC registers of the BD71847 to set and get the time.

Hi,

The SJA1110 switch does not inherently support STP or any of its variants like RSTP MSTP or ERPS . However, it does support 802.1CB, which is a standard for Frame Replication and Elimination for Reliability.

802.1CB can be used to prevent loops in a network by creating redundant paths and then eliminating duplicate frames.
