Hello,
We have i.MX8M based custom board where Windows is running (WoA) and we need to add RTC to this board via I2C bus.
When we checked source code from BSP W21H2-1-5-0, it uses SNVS/RTC inside of i.MX8M.
When we implement external RTC via I2C, could you advise me what work is needed from viewpoint of software development?

Hello Alejandro,
Thank you for your guide to support external RTC with Windows On Arm.
We want to use EPSON RX8010 which has lower power consumption than internal RTC on i.MX8M.
We also have question about ASL to support this RTC, so I will create another post.
Thanks,
