I am using it as normal, just plug it in, install the system on the eMMc or SD, but it turns off after 10 to 15 minutes on, I can't install anything.
In maskrom mode it recognized the board after many attempts and i am installing the system.
After waiting for a while I always get the same error, that the system can not be installed, when I try to run from the SD I have to make several attempts to disconnect and connect the board so that it can start the system.
