主题中讨论的其他器件:BQ25890、
我正在尝试在 Armbian 上设置 BQ25890 Linux 驱动程序、我使用 Orange PI PC Plus 以及定制的扩展板、该扩展板具有 Zigbee 和使用 BQ25895芯片的备用电池
我已经重新编译了包括驱动程序在内的内核、但当我运行 dmesg | grep bq 时、我总是会得到此响应
[ 2.152205] bq25890-充电器:0-006a 探针失败,错误-22
我已按如下方式设置器件树重叠:
// Overlay for bq25890 // bq25895.overlay.dts /dts-v1/; /plugin/; / { compatible = "allwinner,sun8i-h3"; fragment@0 { target = <&i2c0>; __overlay__ { #address-cells = <0x01>; #size-cells = <0x00>; status = "okay"; ds1307: ds1307@68 { compatible = "dallas,ds1307"; reg = <0x68>; status = "okay"; }; bq25890 { compatible = "ti,bq25895"; reg = <0x6a>; //status = "okay"; interrupts = <0 20 2>; ti,charge-current = <1024000>; ti,battery-regulation-voltage = <4208000>; ti,termination-current = <64000>; ti,precharge-current = <128000>; ti,minimum-sys-voltage = <3500000>; ti,boost-voltage = <5126000>; ti,boost-max-current = <10000000>; ti,thermal-regulation-threshold = <80>; }; }; }; };
我在这里遗漏了什么吗?
