Hello Geert Thanks for the fast answer. I had a look in the ARM-configuration from Debian 10. And there is the following configuration:
> CONFIG_SUNXI_RSB=y ==> OK > CONFIG_MFD_AXP20X_I2C=y ==> OK > # CONFIG_MFD_AXP20X_RSB is not set ==> From my point-of-view: Not OK Please have a look at the description of the configuration item: > https://cateee.net/lkddb/web-lkddb/MFD_AXP20X_RSB.html From my point-of-view, this is the reason of the not initialized AXP813 used in Banana Pi M3.
