RE: Re: Uart missing chars when in Release


Hi Grant,
A small update on this subject.
I found I did not have any optimisation on in the release version.
When I added -Os or -O3 most of the problems disappeared.
I'm planning to try to isolate which section of code makes the
difference and then look at optimising how it works.


Thanks again.			...Laurie:{)
