I have an IOT2050 Advanced (6ES7 647-0BA00-1YA2 FS04) and downloaded two example images here: https://support.industry.siemens.com/cs/us/en/view/109741799:
- IOT2050_Example_Image_V1.3.1.zip (820.3 MB)
- IOT2050_Example_Image_V1.1.1.zip (658.6 MB)
After downloading, I compared the SHA-256 of both files to check if the download was correct and both Files are ok.

I used three softwares to write the images files into Micro SD Card (SanDisk MicroSD A1 HC I Class 10 - 100Mb/s 32Gb): imageUSB v1.4, rufus-4.4 and Raspberry PI Imager v1.8.5. All softwares return an error after recording and checking the images.

I also used two differents empty cards, two different micrSD readers/writers and two PCs during the tests. All tests reported the same problem.

I guess that image files could be corrupted​. Is there another site/versions that I can download the examples images ? Do you have any suggestion to write tha images into MicroSD Cards?
