I changed my drone from a Raspberry Pi 3 to a 4 in order to increase processing speed and use USB 3.0. After that, I checked the rotation of the motors using RC and found an anomaly: the rotation of the motors in two places gradually weakened and stopped. Can you tell me the cause of this? Also, is NAVIO2, which I got before Raspberry Pi 4 came out, compatible with Raspberry Pi 4?

Detailed problem description. How does expected behavior differ from the observed one?
Normally, all the motors should be spinning at the same speed, but two of the motors were spinning weakly and stopped after a while.
Your step by step actions.
I changed the NAVIO2 to something else with the same result, and I can confirm that there is no problem with the ESC.
