Wretch Posts: 6 Rating: (0)	Hi What can I do if my IOT2050 no longer boots from the eMMC? The boot order is set as follows: 1. eMMC 2. SD card. The status LED lights up red after a certain time after power on. How can I reset the Iot2050 to factory settings? Thank you very much for your help. ------------------------------------------------------------------------------------------ Split from How to reset IOT2050 to factory state?.

The Industrial OS is supposed to be, but this is not the case at the moment. So if you need the Industrial OS, please send a PM to me with your email address. If you want to use the Example on the eMMc instead of SD card please follow this tutorial. Best regards!

stockipa Posts: 6 Rating: (0)	Ah well, thank's for the info. I thought that it's preinstalled because it says so in the sticky thread: https://support.industry.siemens.com/tf/ww/en/posts/release-of-iot2050/235023/?page=0&pageSize=10 preinstalled Simatic Industrial OS 2.0 (incl. License) on the eMMc I'll contact you asap, meanwhile I'll check out the tutorial for the eMMC example image. Thanks!
