Interfacing (DSI, CSI, I2C, etc.) • Re: [SOLVED] RPi 5 1-Wire / DS18B20 is unstable

With the 6.6.16-kernel it works perfect, using a single Python-testprogram with 3 sensors. For more than 12 hours absolutely no errors.

But if i start an additional task, for example the SD-Card-Copier from the NVME-SSD to an USB-SSD, about 95% of the 1-Wire-reads have CRC-errors.

This is expected if you have something that's disrupting the process doing the bitbash. Linux is not a realtime operating system - there is no guarantee that a delay of N microseconds will only delay you for exactly N microseconds.
