IF someone can advise, please.
I am trying to port eCos to my 850 board.
To the point of "Hello" sample program,
it was not so difficult. However, so far,
I can not run thread program, which uses
"cyg_thread_delay".
I assume eCos "ticks" are generated by
decremeter.
Trial one: Decrementer disabled
It goes infinite loop of "thread idle".
Probably ths is suppoased to do.
Trial two: Decrementer enabled
eCos won't resume threads, and Program counter
loops around 0x000020~30, where I don't
know what lies beneath.
If someone have similar experience, please
advise.
best regards,
