QNX BSP for BeagleboardXM + HIL with xpcTarget
Hi,
I am trying to setup a hardware-in-the-loop enviroment with my BeagleboardXM board and communicate with the xpcTarget
with Matlab model through RS232. The problem is that I could read data from xpTarget to my program running on the board
with QNX but I could not perform write data operations to xpcTarget. Another way of saying, I could not close the loop.
I tried many variations of sample time rating for data send/receive in order to understand are there synchronization
issues and tried code modifications but it could not possible for me to understand what is the real problem. I have same
idea about what might be the problem as,
1- Does QNX for beagleboardXM requires software flow control for RS232 comm? If so how it can be disabled? Or any such
kinds of protocols are required for succesful communication?
2- Does QNX generate interrupt to the serial driver sometime in a way that it can stop xpcTarget execution?
3- Does QNX interrupts generated by some other code parts in the program for different purposes cause xpcTarget to stop
execution?
4- Is it possible to arrange such xpcTarget setup for beagleboardXM + QNX combinations? If so what would you recommend?
Apart from these questions, I don't know why but I could not use readcond or select functions in my setup; because I
think I fail to setup serial device raw mode settings.
I really need some help,
Thank you.
