在Orangepi4 lts上使用wiringOP的softPwm功能就死机
TrinityLeaves opened this issue · 2 comments
使用设备：Orangepi 4 lts
系统：Orangepi4-lts_3.0.6_ubuntu_jammy_desktop_xfce_linux5.18.5
Orangepi4-lts_3.0.6_ubuntu_focal_desktop_xfce_linux5.10.43
Orangepi4-lts_3.0.6_debian_bullseye_desktop_xfce_linux5.10.43
（以上三个系统均尝试过都会卡死）
程序：wiringOP的examples里的softPwm程序
原先是用python调用发现会死机，换了好几次系统发现使用example中的softPwm.c也会死机，更换了一次设备（tf卡拔过去的）也是一样的问题，因此怀疑是wiringOP的问题，如果4lts实在不能用的话，就只好考虑其他机型了
