Still not repropducable. * Tested with small test application (see Forum) * Testprogramm also runs when starting from startup folder on boot * Also tested with old hardware (V1.00) Debug trace in forum shows that 2 serial interfaces are initialized. COM1 is disabled due to debug output (also shown in debug trace). So COM3 (UART2) must be enabled for any reason. But UART2 will only be available in HW Revision 1.20. But anyway, even after enabling this "faulty" interface on old revision, the problem is not reproducable. |
