real time linux probelm
Hi All,
I have a board contains ARM processor shipped with Linux kernel 2.6.21. I have applied real time patch to the kernel namely Quote:
1. the application seems to be hanged, it seems to get into infinite loop but when i press any character on minicom, the printfs are out to STDOUT. i thought it was a problem in buffering the printf, i have forced it to be unbuffered but it make no difference. 2. as for the timers, when i use gettimeofday on the normal linux kernel (non real time), for 2 consecutive lines, i got different ouptuts in the field of tv_usec but after using the real-time patch i found that the result of gettimeofday for 2 consecutive lines are exact the same. can anyone help me or can guess what is the problem? thanks |
Hi.
Can you elaborate more about your steps after you applied your real time patch?. I guess you are using RT_PREEMPT real time patch. I would like to know that your board vendor ensure that your real time patch already tested for this board?. Provide your ARM processor details also. |
