I missed this function earlier.

Well done !

Code:
roboio_SetRBVer(RB_110);

I don't know if this is the correct way or not :/

I think it is related to cpu id.

In libsrc/common.cpp file from robio sources, can you modify roboio_CheckRBVer function as follow, just to display cpuid in the error message :
Code:
RBAPI(bool) roboio_CheckRBVer(void) {  // called only by io_Init(); the caller must ensure that I/O ports can be accessed by this function
        int  cpuid = io_CpuID();

        switch (roboio_GetRBVer())
        {
            case RB_100b1:
            case RB_100b2:
            case RB_100b3:
            case RB_100:
                if (cpuid == CPU_VORTEX86DX_1) return true;
                break;
            case RB_100RD:
            case RB_110:
            case RB_050:
                if (cpuid == CPU_VORTEX86DX_3) return true;
                break;
            default:
                   err_SetMsg(ERROR_RBVER_UNKNOWN, "unknown RoBoard version");
                   return false;
        } //end switch (ver)

           err_SetMsg(ERROR_RBVER_UNMATCH, "unmatched RoBoard version, cpuid=%i",cpuid);
           return false;
    }


I think you are in the RB_110 case but that cpuid does not match CPU_VORTEX86DX_3.

It says:

Code:
Unable to open port
unmatched RoBoard version


I've downloaded the roboIO code for gcc... There was no option for switch between rb110 and rb100 or something else during compilation... is there?

Code:
std::cout << roboio_GetErrMsg() << std:endl;


like that :

Code:
#include <com>
#include <iostream>

int main(int argc, char *argv[])
{
    if(com1_Init(COM_HDUPLEX))
    {
        int i=0;
        while(i<1000)
        {
            com1_Write(0x55);
            ++i;
        }
        std::cout << "100 000 bytes has been written to port COM1" << std::endl;
        com1_Close();
    }
    else
    {
       std::cout << "Unable to open port" << std::endl;
       std::cout << roboio_GetErrMsg() << std:endl;
    }
    return 0;
}


And tell me what it gives.

Yes.

I changed inittab content to directly login into debian with root user and no password. (don't want to connect a keyboard !!) and after logging with ssh I always do
Code:
sudo -i

and then execute the above code.

Note 1: Console redirection is off.
Note 2: I also tried COM 4 and COM 3 ... no hope :-|

This is my first post on this forum :roll: I'm trying to send / receive data on COM1 (RS232) port of rb-110 board. have tried QSerialDevice and ROBO-IO library, ports are always closed or unable to open them... This is a simple c++ code to write some data on com1:

Code:
#include <com>
#include <iostream>

int main(int argc, char *argv[])
{
    if(com1_Init(COM_HDUPLEX))
    {
        int i=0;
        while(i<1000)
        {
            com1_Write(0x55);
            ++i;
        }
        std::cout << "100 000 bytes has been written to port COM1" << std::endl;
        com1_Close();
    }
    else
    {
       std::cout << "Unable to open port" << std::endl;
    }
    return 0;
}


Output is always "Unable to open port"

What I'm missing?
