Hi All

I am new to NetBSD and i am porting it on a ARM926 based SOC.

I m facing following problems

1. Using JTAG debugger , i am not able to debug values of variables
properly, i changed oprimization level from O2 to O0, but
   facing same probem. I am facing problem specially in debugging
"struct timeval" fields


2. In implementing tty layer calls in my serial driver, the xxx_start
function is being called again,,, before previous data is finished
   completely,, I will like to know,,,how tty layer is manages
synchronization with below layers ?

Thanks
