SIMATIC IOT2050 Advanced PG2: STAT LED not blinking

Hello! As you have an IOT2050 Advanced you need to specify which boot target you want to address.

Following your attachment your boot order is as following:

boot_targets=usb0 usb1 usb2 mmc0 mmc1

So after you power on your device it tries to boot in the following order:

1. usb0 - usb2 = your USB ports
2. mmc0 = your SD card
3. mmc1 = internal eMMC on the Advanced

You can try to interrupt the boot process using an UART cable and then use

printenv boot_targets

in the u-boot-shell to confirm this boot order.

Normally it should boot from eMMC by default.

Maybe you can try to flash your image again or use another SD Card (we have good experiences with SanDisk Ultra).

If this will not fix your problem can you please provide the full output of your device (capture it with UART connection and PuTTY) as a text-file.
