    Hello Venkat,

    Debug Time! You would need to ascertain why the software is crashing. Since you have a simplified example of LCD with USB, you have to ascertain the crash requirement. The first thing to check is if the RESC shows a Brown Out, or a Power On Reset due to excessive current drain. Make sure that the bits are cleared?
