I have checked on my BBG3.0, that the time is correctly kept after a shutdown. My KCONFIG has this:
# # on-CPU RTC drivers # # CONFIG_RTC_MXC is not set # CONFIG_RTC_DRV_MXC_V2 is not set # CONFIG_RTC_DRV_IMXDI is not set CONFIG_RTC_MC13892=y # CONFIG_DMADEVICES is not set CONFIG_REGULATOR=y # CONFIG_REGULATOR_DEBUG is not set # CONFIG_REGULATOR_FIXED_VOLTAGE is not set # CONFIG_REGULATOR_VIRTUAL_CONSUMER is not set # CONFIG_REGULATOR_BQ24022 is not set CONFIG_REGULATOR_MC13892=y CONFIG_UIO=y # CONFIG_UIO_PDRV is not set CONFIG_UIO_PDRV_GENIRQ=m # CONFIG_UIO_SMX is not set # CONFIG_UIO_SERCOS3 is not set Please check that: CONFIG_MXC_MC13892_RTC=y Also, on my BBG3.0 board, I am measuring 2.69V on the coin-cell. Can you measure on your board what is the coin-cell voltage? -- hardware clock not saved if board power is removed on babbage 2.5 https://bugs.launchpad.net/bugs/427289 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
