“线程”中讨论的其它部件: AM4372
香榭丽舍大街;
客户希望解决一个请求。
他们的目标设备是 AM4372BZDN60S。 但由于提前期问题,他们必须使用 AM4378BZDNA100S 组装 PCB。
请告诉我们如何使用 AM4378BZDNA100S 配置引导加载程序和内核端以将设备设置为600MHz。
谢谢。

你好,刘斌
我应该看看 am33xx.dtsi,而不是 am43xx.dtsi 吗? 我无法找到来自 am43xx.dtsi 的 opps
是否需要删除 am33xx.dtsi 中下一行的 opp120-600000000行的 opp?
opp120-600000000 { opp-hz = /bits/ 64 <600000000>; opp-microvolt = <1200000 1176000 1224000>; opp-supported-hw = <0x01 0xFFFF>; }; opp120-720000000 { opp-hz = /bits/ 64 <720000000>; opp-microvolt = <1200000 1176000 1224000>; opp-supported-hw = <0x06 0x0080>; }; oppturbo-720000000 { opp-hz = /bits/ 64 <720000000>; opp-microvolt = <1260000 1234800 1285200>; opp-supported-hw = <0x01 0xFFFF>; }; oppturbo-800000000 { opp-hz = /bits/ 64 <800000000>; opp-microvolt = <1260000 1234800 1285200>; opp-supported-hw = <0x06 0x0100>; }; oppnitro-1000000000 { opp-hz = /bits/ 64 <1000000000>; opp-microvolt = <1325000 1298500 1351500>; opp-supported-hw = <0x04 0x0200>; };
谢谢。
