Hello,

well, I am a new user of linux and I will try to do something with ARM9 with linux.

My problem is that I want to use a comunication port. I have not any problem to open device and configurate, but when I try to read and write I have a lot of problems. My kernel use path of Ingo Molnar to reduce lattence of task.

My idea is to create a thread with read and write orden to recieve and send message using port comunications.

Well that is all.

Best regards
