Re: Re: [ECOS] Problems with tcgetattr()

[Andre-John Mas]

Just wanted to add a small correction, based on further tests:

If you set the 'Default console device' to be '/dev/termios0',
or any other termios compatible device, then your code can quite happily do tcgetattr() on 'STDIN_FILENO', since it is now mapped to the termios device. At least, this is how it is working for me :)

Re: Re: [ECOS] Problems with tcgetattr()

[Andre-John Mas]

I got it working finally :)

For the benefit of others, the following posting helped:

http://ecos.sourceware.org/ml/ecos-discuss/2002-07/msg00092.html

to quote the relavent instructions:

1) In the "Serial device drivers" section, I enabled the "TTY-mode serial device drivers" subsection (CYGPKG_IO_SERIAL_TTY = 1).
2) In the "TTY-mode serial device drivers" subsection, I enabled the "TTY-mode channel #0" subsection (CYGPKG_IO_SERIAL_TTY_TTY0 = 1).
3) In the "TTY-mode channel #0" subsection, I specified "TTY-mode device channel #0 device" as "/dev/ser0" (CYGDAT_IO_SERIAL_TTY_TTY0_DEV = "/dev/ser0")
4) I also did 2 and 3 for "TTY-mode channel #1" subsection, but this may not be necessary
5) Check the "Hardware serial device drivers" sections thoroughly to make sure they are what you want for /dev/ser0 (and /dev/ser1 maybe)
6) In the "ISO C Library" section, "ISO C Library standard input/output functions" subsection, I specified "Default console device" to be "/dev/tty0" (CYGDAT_LIBC_STDIO_DEFAULT_CONSOLE = "/dev/tty0")

in addition to this I activated the value

CYGDAT_IO_SERIAL_POWERPC_QUICC_SMC_SMC1

and set the device name to

"/dev/ser0"

Step 6 above I used '/dev/termios0', instead of '/dev/tty0'. I then in my source code referred to '/dev/termios0' as suggested by Andrew.

Re: Re: [ECOS] Problems with tcgetattr()

[Andre-John Mas]

I updated the variable to match the values in CVS and everything now
compiles. Though I am still stuck as what I need to do to get
tcgetattr() with our Adder II based board.

Re: Re: [ECOS] Problems with tcgetattr()

[Andre-John Mas]

Trying to see if I can get things working myself, I have activated
the option in the ECC file for "Termios TTY channel #0", but when
I compile I get the error:

packages/io/serial/v2_0_51/src/common/termiostty.c:189: error: `B5000000' undeclared here (not in a function)

Searching the packages I have I find no defintion for 'B5000000' or
any of the values defined in the variable defined at that line:

  static speed_t ecosbaud2posixbaud[]

Any ideas?

Re: Re: [ECOS] Problems with tcgetattr()

[Andre-John Mas]

Fair enough. I have added the following code:

   char*  deviceName =  "/dev/termiosX";
      
   fd =  open(deviceName, O_RDWR | O_NOCTTY); 

but this fails at the 'isatty(fd)' test. Changing the device name
to to the value specified by 'console device name',in the ECC file:

  "/dev/ttydiag"

gives me the same error as when I used STDIN_FILENO:

 tcgetattr: Invalid argument

Any ideas?

You are thinking in Unix way, not the eCos way. termio controls only
work on the termios devices and no other devices.

However, there is currently no ssh or telnet daemon for eCos, so when
you implement these things, you can add support for this in however
you implement telnet or ssh.

Also, not there is no concept of a per thread STDIN. It is one STDIN
for the whole system.

Re: Re: [ECOS] Problems with tcgetattr()

I am trying this on STDIN_FILENO, based on examples I have seen posted on the net. Currently I am connecting via the serial port, but later on it is likely to be via a telnet or ssh connection. I thought STDIN_FILENO was meant to be mapped to the current device?
