On the Original Prusa XL, the I2C bus is used for the XLBuddy to communicate with other printer components. All communication is expected to occur within a timeframe: if this does not happen while data is being received by the XLBuddy, the printer will show the message: "HAL detected an I2C timeout when receiving data via I2C."
Error name: I2C Receive Timeout
Error code: #17317
Restarting the printer is expected to resolve the error, and this is not expected to occur again. In case a restart does not resolve it, please contact our customer support, we will take it from here.
