Hi All,
I have an issue with kernel panics in Android 7.1.2 with custom board (board based on sabredsd design, same pmic, memory), which is working without any problems with Android 5. I checked memory with freescale ddr_stress_tester and it's work fine. The board work with Android 7.1.2 from few minutes to few hours and then get kernel panic, display is freeze or board reboot.
Maybe someone have simillar issue and can help or have any idea how to solve this issue.
Thanks.
More details in included files.
