Two UARTS

[Aitor.Viana.Sanchez at esa.int]

OK,

I already tried with this code.

       fp = fopen("/dev/console_b", "r+");
        if(fp == NULL)
            std::cout << strerror(errno) << std::endl;
 
....

    fprintf(fp, string);
    fflush(fp);

where string is a char* passed as an argument to the routine containing 
the fprintf.

The problem is that the fopen routine returns "No such file or directory" 
error.

In the RTEMS configuration file this options are specified

#define CONFIGURE_LIBIO_MAXIMUM_FILE_DESCRIPTORS    10
#define CONFIGURE_NUMBER_OF_TERMIOS_PORTS           2
#define CONFIGURE_USE_IMFS_AS_BASE_FILESYSTEM


In principle, as far as I read, should work, but it does not. Has anybody 
any clue?


Cheers,
        Aitor

Two UARTS







Hi everyone, 

I've got, for sure, and stupid question. I am working with the RTEMS for 
LEON architecture. I know that the standard output is connected with the 
UART1, but I also have an UART2. I would like, from a user application, to 
send some trace information out through the UART2...which the easiest way 
to do that? 

Cheers, 
        Aitor

I suspect the port files are horribly out of date.  For sure, they do not 
distinguish between 4.6, 4.7, and 4.8.  So that's a bad sign. 
Here are the tool versions listed in the arm-rtems-gcc Portfile: 
  
gcc 3.2.3 
newlib 1.11.0 
gcc-${version}-rtems-20030507a.diff
newlib-${newlibversion}-rtems-20030605.diff 
  
That looks suspiciously like an older 4.6 toolset. 
  
$ /opt/rtems-4.6/bin/arm-rtems-gcc --version 
arm-rtems-gcc (GCC) 3.2.3 (OAR Corporation 
gcc-3.2.3-20040420/newlib-1.11.0-20030605-4) 
  
So it needs to be updated in various ways.
