Hi,
I have a multi threaded program consists of just two threads on ARM 7TDMI
SOC target. The program is running fine if the eCos is built with "Bitmap
Scheduler" option, I am able to create Mutex and cyg_thread_delay() is also
working fine. If I use "Multi Level Scheduler with Time Slicing Enabled"
option the program is hanging at cyg_mutex_init() and no thread is working.
The cyg_thread_delay() is also hanging.
Why the cyg_mutex_init() is hanging in Multi level scheduler and not in
Bitmap scheduler?
Why cyg_thread_delay() is hanging in Multi level scheduler and not in Bitmap
scheduler?
Please help.
Thanks in advance...
Shobhan
