CPU locks up shortly after arming?

[elitak]

Shortly after arming, or immediately if I throttle up, the OSD locks up and the motors stop, as though it just crashes after using like 2mAh or something. I have no props on, am running 6s with no current sensor, on HELIOSPRING v3.4.2, 32/16kHz. X-racer 32bit Quadrant ESCs running BLHeli v32.2. I also tried without dynamic_filter and at 8kHz/8kHz with no 32Khz mode, DSHOT600.

It feels like I'm missing something basic, but I've never used this FC or ESC set before, so I can't really tell. I also can't fall back to Betaflight for this board to see if the problem is in the Butterflight firmware.

Elided sections are defaults:

@gke I think you meant to post this in another issue?

Thanks Eric . Should have been #58.

[orneryd]

yeah see #58 for more information. We really need to disabled dynamic in the UI when it's the helio target. It doesn't do anything since the code is removed :)

This is a dupe, I guess, but my failure was almost immediate, in contrast. I fixed the problem by spacing the board from the ESCs a good distance (needed about 10mm I think?). The inductor on the FC was only a millimeter or so from a row of capacitors on the ESC, so probably some EF was causing the brownout.
