Dear Reinhard Meyer,
In message 4CC68A07.6050109@emk-elektronik.de you wrote:
Also, this code _is_ a bit different, as "get_timer(0)" makes sure the counter starts ticking again at 0
Nope, it does not reset the counter itself. It returns the current counter value (recalculated into CONFIG_SYS_HZ units). Maybe you mean reset_timer() instead?
Yes, you are right, I was wrong.
have millisecond resolution.
Actually CONFIG_SYS_HZ (whatever that is).
It is defined to be 1000.
I think it is necessary to summarize all implicit or explicit documented "defined to have's" regarding the timer and then to verify that all implementations adhere to them.
Indeed - documentation is an are where U-Boot has a serious lack.
Best regards,
Wolfgang Denk

It's certainly convenient the way the crime (or condition) of
stupidity carries with it its own punishment, automatically
admisistered without remorse, pity, or prejudice. :-)
