 ## Known Issues
 
 * spontaneous reboot, especially in case of intensive web server access
-* stopping automated tflite flow - Error teared down to alignment procedure (results in restart)
-* Camera initialization stuck not often, but randomly 5s after reboot - Hard reboot (power on/off) necessary :-(
-  --> Next try: adopted reboot sequence with additional and extended camera reset
+* stopping automated tflite flow - Error teared down to alignment procedure (results in restart) - Image load fails
 
 
 
 ## Solved topics
