[Bug] Matek H743-slim-v3 PWM outputs S3, S4, S5, S6 don't work
Describe the bug
In px4 (both release 1.14.1 and latest master) outputs S3, S4, S5, S6 (PA0, PA1, PA2, PA2 attached to TIM5) don't output any signals (tested with oscilloscope) both in PWM and DSHOT modes. The same hardware with Ardupilot works fine.
To Reproduce
- make matek_h743-slim upload
- In QGC select copter profile and assign motors to outputs S1, S2, S3, S4
- Attach ESCs (or oscilloscope probes) to these outputs
- Motors on S1 and S2 will beep, but S3 and S4 will be silent
Expected behavior
Expected that S3, S4, S5, S6 will work. Other outputs (S1, S2, S7 - S12) works normally. It seems that something bad with DMA and/or timer mapping.

+1 waiting for a long-term solution
@IgorSheyko I didn't found solution in this video except of to ignore S3-S6 outputs.
