Hi, I assume you are running Industrial OS. To reinstall the image you need to erase the eMMc at first. Otherwise you will stuck in booting to the USB flash drive, if the first boot target is the USB drive. To erase the eMMc you need an Industrial OS or Example Image running on an SD card or USB drive.
The IOT2050 boots from the Service Stick and after installing the image it reboots into the eMMc and you can do the setup of Industrial OS. Another, more easy solution without erasing the eMMc at first, would be to use an UART cable (e.g this one) and establish a serial connection to the IOT2050. Somewhere in this post you can find how to establish a connection with this cable. Once the connection is established (before powering on the device) you can press any key during the boot until you end up in the so called u-boot shell (=> at the beginning of the line indicates that you are in u-boot shell)
Best regards! |
Not working for IOT2050 support anymore from March 1st, 2024. |

I've tested all two USB ports available in the IOT - unsuccessfuly. Attached you can find the env print result. I'm wondering whether maybe the USB stick is flashed wrong way or something... But I flash it with balenaEtcher (which is recommended by Siemens I guess, it's mentioned in all documents when flashing an image is necessary), I never had problems with booting from USB sticks prepared this way and I'm using the example image from Siemens, not any other unofficial distros... When it comes to mmc0, I noticed that after plugging the SD card in, there are cyclical errors in the Serial terminal visible:
But completely have no idea how this can be fixed. On another IOT2050 booting from SD card works perfectly and it can be read without any issues. Attachmentenv_print.txt (544 Downloads) |

I did but unsuccessfuly - the error is the same, no matter what tool I use for flashing the image. |
