20240619在飞凌OK3588-C的LINUX系统启动的时候拉高3个GPIO口141-111-120【方法一】
2024/6/19 16:12

缘起：在凌OK3588-C的LINUX R4系统启动的时候，需要拉高GPIO4_B5、GPIO3_B7和GPIO3_D0。
修改rcS，在系统启动的时候，即可拉高。
通过adb pull拉去rcS到WIN11上，修改之后adb push到OK3588-C即可。
还需要修改rcS的权限！

【失败】
尝试修改SDK/系统中的rcS，尝试让系统编译的时候直接拉高GPIO4_B5、GPIO3_B7和GPIO3_D0。
编译完成之后的IMG刷机之后，发现
