My slightly modified helloDSP example is crashing with this console output(UART1):
irq 53: nobody cared (try booting with the "irqpoll" option)

Disabling IRQ #53
That IRQ is for UART1. After which, the console is unresponsive. It takes about 40 seconds after starting the program.
Changes to the helloDSP code:
dsp/tskMessage.c
//led_test(); //Comment this out. Minimize processing time.
gpp/helloDSP.c
replace
else if (msg->command == 0x02)
SYSTEM_1Print("Message received: %s\n", (Uint32) msg->arg1);
with
else if (msg->command == 0x02)
printf("0\n"); // Minimal output.
Note that a simple ARM app like this doe not cause the error.
int main(int argc, char *argv[])
{
for(;;)
printf("0\n");
}
Any comments would be appreciated.
