This two parts to make it work with the PocketBeagle, first is the patch you have and then also configure the RTC in u-boot to use an internal 32Khz reference: U-boot doesn't make this too easy, so some things need to be moved around.. https://github.com/RobertCNelson/Bootloader-Builder/blob/master/patches/v2019.04/0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch#L185-L207 Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
