Hi Ivan, I have an A20 Cubieboard, is yours the same ? I can see the crystal on the board top next to the DRAM but I'm sure this is the 24Mhz crystal for the CPU. There is also a 25MHz crystal under the board for the emac phy.
My RTC is running at a varying natural frequency. It gains/loses between 16 seconds and about 20 minutes per day probably depending on the temperature. But my CB2 is working and this is why I'm reluctant to drill holes in a attempt to connect to F1 and F2 balls on the SoC for the 32kHz crystal. I agree that the A20 RTC is fine. My CTs and OPi are all using this and keep time while powered off. Does the LOSC_CTRL_REG setting specify whether to use the internal oscillator or an external source ? Just a guess.
