Hi Andreas,

Yes, there is a plan to fix this. However, the silicon and the fix have to be validated before TI can guarantee that the issue has been resolved.

Best Regards

Hi David,

If your AM335X is silicon Rev.1.0 there is nothing you can do. The only ways to solve this issue are to replace the processor with Rev.2.X, or use an external RTC, or if your design is with the TPS65910A PMIC you can use the PMIC's RTC.
