BETA edition rcu errors

[8bit]

Some users have reported "time travel" or general instability issues when the DRAM inside the PinePhone is configured to run at a higher frequency.  I would suggest that you try lowering the DRAM frequency and see if the issues go away.

Manjaro ARM builds and packages a few variants of U-Boot for the PinePhone, which allow different DRAM frequencies (492, 528, 552, 592 and 624 MHz) to be easily tried out.  Just write the desired variant of the U-Boot to your boot device, reboot and test.

See also this thread for further information.

Thanks. Testing it now at 492MHz on Manjaro Plasma.

Code:

sudo cat /sys/kernel/debug/clk/dram/clk_rate
