Hi. In SoC EDS version 20.1, the alt-boot-disk-util SD card utility doesn't work, it always returns "Device open failed" error message regardless of running as administrator, specified destination drive etc.
alt-boot-disk-util from SoC EDS version 18.1 works fine on the same computer.
Could you try starting the Embedded Command Shell with Administrator Privileges before trying invoking the "alt-boot-disk-util" exe?
Which board are you working on currently?
