MCB900: HELLO Example Does Not WorkInformation in this article applies to:
SYMPTOMI am using the µVision v3 - LPC Development Studio - 5.2004 and I have downloaded the example Keil\C51\Examples\LPC9xx\Hello. The LED's are flashing, however no text is printed on the UART interface. CAUSEThe startup code (START900.A51) file is incorrectly configured and the execution of the MOVC instruction is protected. Therefore, the printf statement cannot correctly read the "Hello World" text from the Flash ROM. RESOLUTIONOpen the file START900.A51. Uncheck all options under Flash Security Configuration. This enables the execution of the MOVC instruction in the Hello example. MORE INFORMATION
