回复: How to test meson_gx_pm

[张 宁]

Thanks Neil.

Wake up sources are configured in BL301, no related  to other parts of U-boot.

Hi, Nick

are these wake up sources (power  key, IR, bluetooth) correctly configured?

Any wakeup source configured in bl301 code embeded in the FIP bootable binary should work.

Usually Bluetooth & IR are configured in addition to a power key, but the vendor u-boot source

should be checked to confirm.
