I've connected a [BetaFPV ELRS Lite](https://betafpv.com/collections/rx/products/elrs-lite-receiver) to a [REVONANO](https://librepilot.atlassian.net/wiki/spaces/LPDOC/pages/26968079/OpenPilot+Revolution+Nano) (for ease of swapping between the ports as they're pluggable) running 4.3.1 and it works without issue on both the Main...

Also, are you powering from USB or a battery?

@CapnBry The DFU reference threw me. Your explanation makes more sense. As you say, scoping the power on behaviour is the only way to establish what’s going on.

I’ll look to see if a pull-up can be configured on UART lines.

What do `timer`, `timer show`, `dma` and `dma show` report?

@hydra I note that that the ICM426xx driver doesn't support gyro DMA nor scheduler locking as it doesn't use the `acc->readFn` and `gyro->readFn` support in `accgyro_mpu.c`. Happy to fix if...

Hi @hydra I was waiting for you get basic support for the H7RF in master. Once that’s in place I can add the DMA support for that gyro.

Tested on a BETAFPVF4SX1280 and appears to function perfectly.

From some brief testing it would appear that black box recording stops randomly unless `blackbox_sample_rate` is set to `1/1`. This will require some investigation.

When debugging I'm seeing that the logging stops due to the following being called in msp.c. The question is why is the configurator disarming if I change tabs? @limonspb ?...
