But I'm trying to build the TI's example how to init new UART (USCI). Even in the same configuration as in example. "Simple" interrupt - say, timer? Good idea, I'll try to do this. In result I will know is the problem connected with IO interrupts or all interrupts. But, basically firmware seems running on the first sight - I may trace it in the debugger, turn on / off leds and so on. I even can write data in UART. Just UART interrupts do not work. The problem also that I probably can't fix this compiler myself even if I found the reason. --- Regards, Dmitry > > >> R# > >> > >> 2009/4/1 Dmitry Zuikov <[email protected]>: > >> > Greetings, > >> > > >> > Could anybody provide an assistance (not for free, of course) porting > >> > our application from MSP430F1612 to MSP430F2418 ? > >> > > >> > I faced problems even when I try to launch an example from TI site > >> > adapted for gcc (code is below). > >> > > >> > This code works ok under IAR, but there is no any response in port under > >> > MSPGCC. > >> > > >> > I built mspgcc from cvs. > >> > > >> > code (adapted MSP430x261x_uscia0_uart_03.c ) > >> > //****************************************************************************** > >> > // MSP430x26x Demo - USCI_A0, Ultra-Low Pwr UART 9600 Echo ISR, 32kHz > >> > ACLK > >> > // > >> > // Description: Echo a received character, RX ISR used.
