Hello Everyone, I’m new to this stuff and i’m experimenting with an Olimex Lpc2106 board using FreeRTOS. I have some problems with the Uart Driver though (the one included in demo application). I have three tasks, the two of them blink 2 leds, and the third is used for sending a string to uart0 and receive something. I use Teraterm as terminal. The problem is : When I receive ONE char, everything works well, and I can resend it to Uart : xSerialGetChar( xPort, &jimR, comRX_BLOCK_TIME ); xSerialPutChar( xPort, jimR, comNO_BLOCK ); But, when I want to receive a string, using an array variable, if I send any char everything hangs. (Assume I send only 2 chars) char *array; xSerialGetChar( xPort, &array[0], comRX_BLOCK_TIME ); xSerialGetChar( xPort, &array[1], comRX_BLOCK_TIME ); This does not happen if  I use two different variables for my two chars : xSerialGetChar( xPort, &jimR, comRX_BLOCK_TIME ); xSerialGetChar( xPort, &jimR2, comRX_BLOCK_TIME ); xSerialPutChar( xPort, jimR, comNO_BLOCK ); xSerialPutChar( xPort, jimR2, comNO_BLOCK ); Any thoughts..? Regards, Dimitris

char *array -> This only defines a pointer to a character, not an array. You need char array[2].
