Hi List,
I am working on ARM920T (Integrator) and ecos. I have configured my kernel
with posix and Serial device drivers. following options are enabled in my
config file.
CYGOPT_IO_SERIAL_SUPPORT_NONBLOCKING
CYGPKG_IO_SERAIL_TTY
CYGPKG_IO_SERIAL_TTY_TTY1
CYGPKG_IO_SERIAL_DEVICES
CYGPKG_IO_SERIAL_ARM_INTEGRATOR_SERIAL1
I want to configure my serial port in RAW mode. i think ecos supports
two serial port drivers (raw and tty driver). Is there any explicit option to
specify for RAW drivers. I tried to disable (CYGPKG_IO_SERAIL_TTY_TTY1)
option, i wasnot able to read/write anything from serial port even opened
successfully.
I tried to use OPEN call also. i got compilation error due to
unresolved symbols `O_NDELAY' ,`B115200' ,`CLOCAL' ,`CREAD' . i have
decleared terminos.h ..
Any lights to move furthur..
Thanks
Prakash
