Hello, I recently had a problem with two IOT2050 modules (6ES7647-OCA00-1AA2). I follow all the instructions to boot using a microSD card with the recommended image properly written via Win32 Disk Imager, and as soon as I power the device with the microSD inserted, the STAT button turns green for a moment and then stays solid red. I have already tried different firmware versions and multiple microSD cards, and the power supply is correct. I cannot find anywhere what is causing this issue.
