Hi,
My board has a 16c550 type uart,I'm using the ecos generic 16x5x serial driver for the same. (packages/devs/serial/generic/16x5x/v2_0/src/ser_16x5x.c)
After I've enabled the interrupt driven mode in the driver,I am continously seeing the interrupts, ( INTERRUPT IDENTIFICATION REGISTER - the received data available is always set) the interrupt is not getting cleared, and we have to reboot the system.
CYGDAT_LIBC_STDIO_DEFAULT_CONSOLE is /dev/tty0
CYGDAT_IO_SERIAL_TTY_CONSOLE = /dev/tty0
CYGDAT_IO_SERIAL_TTY_TTY0_DEV is /dev/ser0
Can any one give me some clues where could be the problem.
Thanks,
Saritha
