Has anyone gotten the UART interrupts to work right?
I haven't tried. The only information I can give is that I know the VxWorks bootloader runs with UART interrupts enabled. To use polled I/O, I have to explicitly disable them: #define UART_CR 0x90003800 /* UART Control Register Address */ #define XIE 0x00000100 /* Transmit interrupt enable bit */ #define RIE 0x00000010 /* Receive interrupt enable bit */ void noUartInts(void) { volatile unsigned long *ptrCR = (unsigned long *) UART_CR; *ptrCR &= ~(XIE | RIE); } (Since you stated that you got polled I/O to work, you are probably already doing the same thing.) My recommendation is to look through the code source from the development CD-ROM. It may have the source for the bootloader which would include the interrupt enabling and handling code. Hopefully, someone else on the list can give a more helpful answer than mine. Good Luck, Scott
