esp32 onewire not working since 2019-03-25 updates
I am using the daily build downloads for the esp32 (without psram) and the 2019-03-25 is working fine with ds18x20 sensors but the new build 2019-03-27 always gives me CRC errors.
I can only guess what might be causing this but as within the last few days only one small change to threading and the activation of dual core usage was changed, the problem should lie within these 2 changes.
How to reprodue:
- Connect DS18x20
- Try to read using firmware 2019-03-25
- Confirm that reading works without problems
- Flash firmware 2019-03-27
- Confirm that no reading works, always CRC error

Hello,

With this firmware is everything fine: ESP32_S2_WROVER-20220618-v1.19.1.bin
but i not found the v1.21 from it ... i only found is discussion here in github, that i have to use the generic (but there is this error above)
