Re: CYGNUM_HAL_RTC_PERIOD / floating point

You can find the CYGNUM_HAL_RTC_NUMERATOR aloingside the period

Tried that, and things still seem to not work quite right. I guess
I'll keep experimenting and see what I can find.
Of course too fast, and you would be swamping the machine with interrupts
- it may be spending all its time handling them!
Also check the docs for the timer chip. It may not be able to go that
fast. Should, but may not.
Then in the code use a test like:
That works. Shall I try and create a patch out of it?
Please do.
One more thing - I try and set up a floating point variable in my
cyg_start, and that seems to futz things up but good.
I had a look in the mailing list archives, and tried a few things like
turning off the lazy FPU switching, but to no avail.

386DX? 386SX has no FPU. Does FPU work outside of cyg_start in threads?
