Re: Serial Port , Raw Mode using cyg_io_read


Hi,

Did you tried to open the /dev/ser0 , /dev/ser1 ? Something like:
err = cyg_io_lookup( "/dev/ser1", &fd );

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
