We have a SMBus device which is a MCU designed in our project. We found that we read or write MCU from SMBus, then SMBus will be frozen in Linux OS Fedora and Debian, but Ubuntu and Windows 10 not found this problem. The measurement waveform shows below picture.
Thank you for posting in the Intel Community.
I am noticing that you are developing an SMBus device project, in this case, we recommend going to our Intel® developer zone (https://software.intel.com/en-us) or Intel® Resource & Design Center (https://www.intel.com/content/www/us/en/design/resource-design-center.html) for assistance with development projects.
