I have no image on the eMMC yet.

To bypass the eMMC and force the device to boot from an external medium (µSD or USB): Press and hold the USER button while powering on or resetting the device. Keep holding the button until the STAT LED turns orange, then release it. This action forces the IOT2050 to boot from external media only (e.g., µSD or USB). Use UART to Modify Boot Order If skipping the eMMC does not resolve the issue, you can use a UART connection to manually change the boot order: Establish a UART connection to the IOT2050 using a USB-UART cable. Interrupt the boot process by pressing any key when prompted ("Hit any key to stop autoboot"). In the U-Boot shell, check the current boot order using: fw_printenv boot_targets Here, mmc1 refers to eMMC, mmc0 refers to µSD, and usbx refers to USB slots. Change the boot order to prioritize external devices (e.g., µSD first) with: setenv boot_targets mmc0 usbx mmc1 saveenv Restart the device. If none of these steps will fix your issue we can try to reflash a compatible firmware image. BR
