SV: [Icc-avr] Problem with code compressor

[Steven Lose]

Hi

 

I've had the same experience when the first MIO came out.

At first I just didn't use it, but later on, when I really really needed the last % space, I finally speed the hours on figuring out why, and

not surprisingly, even though my software had run for year's with no problems at many customers, it turned out to be a SW error.

 

Best regards Steven

I've stopped upgrading since V7.12.  I too had lockup problems and variables getting trashed.  Still haven't found out why(don't have the time), but my code runs fine with V7.12.  Strange.

ICCAVR version V7.13A
Increasing stack does not make a difference, and I don't know of any 
time sensitive code. I will try to identify where it is going wrong.
