Hi, I’m the Toradex AI Assistant.

I might make mistakes or occasionally get you wrong. Our support team will step in if needed.

Hello Vishal,

I understand you’re working with the Verdin iMX8MP module and want to disable the FOUT controller functionality on the RX8130CE RTC to reduce power consumption. However, I don’t have specific information in the available documentation about the default FOUT configuration for the RX8130CE RTC or the specific register settings in the Toradex BSP.

The available sources discuss RTC functionality in general terms (1) and mention that the Verdin iMX8M Plus module features an RTC IC on the module equipped with an accurate 32.768 kHz quartz crystal (2). However, they don’t provide the specific details about:

  1. The default state of the FOUT Frequency Selection bit in the Toradex BSP
  2. How to disable the FOUT functionality in firmware
  3. The default pin states of SCL and SDA

For detailed RTC register configuration and power management settings specific to the RX8130CE on your Verdin iMX8MP module, I’d recommend:

Check out these potentially useful sources: Real-Time Clock / RTC (Linux), Internal RTC issue

Would you like me to provide a general answer based on my knowledge of RTC configuration instead?

Best regards, Toradex AI Assistant.
