Prearm: Main loop slow (168Hz<400Hz) on new version V4.5.3

[thiensu1122]

Hi Hefny,

Today I tried to build the new version V4.5.3, and I got the error Prearm: Main loop slow (168Hz<400Hz).

I also noticed that the CPU usage is significantly lower than V4.2.3.

Do you know how to handle this?
Thank you very much,

What is the RPI you are using? Also please send me your settings to replicate it here.

Also please try to run ardupilot as a command line not a service and see what happens. On Sun, Jun 2, 2024 at 2:38 PM Mohammad Hefny ***@***.***> wrote:

Thank you for your quick reply Hefny.

I've tried to run the arducopter without using the arducopter.service but still the problem persists. Then I just turn it off for a while and then turn it on, and now the issue is no more. I have no idea how or why the problem solve itself.

Best regards,
