Motor number 7 wont spin and gives beeps after shifting from betaflight to INAV

[shrivatsa318]

Current Behavior

So I decided to move from betaflight to INAV (my drone is an X8 cinelifter), everything seemed to work fine initially , but then under outputs tab in INAV when I tried to move motor 7( specifically) the motor wont spin,ESC no 7 gives me a beep and nothing happens, so I taught there might be some issue with the esc and so I decided to check the blheli32 configurator for any of the esc issues, I found out esc no 7 had suddenly 117 bad frames, I slightly got worried,so immediately i shifted to betaflight, once I am in betaflight everything works like a charm, all escs function normally and also has 0 bad frames in blheli32 configurator and the drone flyes pedfectly as usual , one more observation that i made was all motors in INAV spins when I push the master slider but when I push the motor no 7 slider individually I have the issue, can anyone please tell me how to fix this in inav.

Many of my friends with the same Flight controller have similar issue, they are like if we change from dshot to multishot the issue will be fixed, but is there a way to make it run with dshot600 itself

I changed how the DMA is done.

Are the number of bad frames increasing, or did it just miss four frames during boot up?

Firstly Bad frames are varying from 0 to 9 so every time I refresh the blheli32 config I am seeing each esc having varying bad frames from 0 to 8
Here are the 2 videos , So in the first video I am not sure why but I get those varying motor sounds not sure if they are functioning fine whenever I disarm the quad
In the second video whenever I disconnect from blheli32 config I get these varying sound tunes , again I am not sure if they are correct
Non of these happens in betaflight so wanted to know if everything is fine with respect to motor beeps and esc bad frames
Thankyou for always replying

I would not be concerned about a few frames missed during power up. If you leave it connected for a while and the bad frames count goes into the thousands, then I would be more concerned.
