Hi We installed WinCE on the smart210 board at first successfully. But installation of linux ends with failure. After trying to install linux we decided install WinCE again. But in this time we encountered with failure same as linux. We can't install any OS on this board now. When we use flash mode(USB-Mode=NO) to install OS, the board resets during the installation. It resets Sometimes on unpacking and sometimes on installing state and starts installation again and again by beeping. When we use USB mode(USB-Mode=YES) to install OS, Minitools executes steps 1 and 2 successfully but during the third step (when installing WinCE or Linux) the USB connection is disconnected and connect again, so the installation restarts again. This event occurs during the fourth step in Android installation. thanks in advance
