Hey forum Another update - Betaflight 3.2 was officially released this month. This is the first release that contains the Crazyflie 2.0 target by default, so you don't need to clone and build from source anymore. It's available as a target in the betaflight configurator from the google chrome store!...

I mean rapid increases to max throttle. The behavior happens most commonly when you go immediately to 100% throttle at takeoff. I can also see it when you go from hover throttle to 100% immediately during flight. The behavior is hard to describe, but it looks like an uncontrolled oscillation or dest...

Hey all, it's been a while. Here's some updates for those who are curious: I've made some changes to how UART is handled that lets us reduce the syslink task priorty. However, I also determined that the massive 20ms+ spikes only happen when connected through USB instead of OTA, so it's less of a con...

Hey, curious if anyone has successfully used 2s lipos (with a connector attached to the terminal on the node) to power the LPS nodes? Seems that would be the cheapest option for mobile power since those USB power sticks seem to be about $10 a piece. My only concern is about preventing over dischargi...

What you stated is correct. When "make flash" runs, openOCD is using the 'autoerase' option which causes all flash from the start through the end of the image to be erased (including the bootloader). Then when the bootloader is flashed, only the portion used by the bootloader is erased, pr...

Do you have any more ideas? Are there lower level bootloaders than DFU mode I can put the chip in? I can't bring myself to believe the chip is damaged or bricked simply from debugging the NRF... That seems unlikely right??

Interesting that it was solved. I wonder if this commit fixed the problem:

I'm using the STM32 discovery board with a STLink adapter on it. I think it's a V1 and not a V2 -- looks like V2 adapters are cheap on amazon so if V2 offers better features that would help me recover the chip I'll gladly order one. I've used DFU mode before and also noticed the extra button press -...

Thanks for the follow up! Good to know that stepping is disabled when Bluetooth is enabled. Strange -- I hope there's a technical reason behind that and it isn't just Nordic trying to protect their IP by hindering debuggability

I do have one functional board left, so I ran some comparisons. Most pins are the same on the good board and the bad board -- voltage supplies look good in both, the BOOT0 and NRST pins are in the correct states, etc. The only difference I found was on the good board, PA13 (STM_SWIO) is high, but it...
