Hi,

I could solve a problem and got the next.

An error message which I saw the first time.

It looks like a problem with __SYSMEM_SIZE, this even I defined the --heap option with 0x2400h!

See attached txt file.

What can I try?

This appears to be a problem with the use of link-time optimization, which you enable by using -O4. I'd appreciate if you would submit the CCS project, so that we can reproduce the problem. In the mean time, lower the optimization level from 4 to 3. I'm pretty sure that will work.

Thanks and regards,

-George

Hi Georg,

I had no succes with reducing the level from -O4 to -O3 or lower.

Because I,ve got the project from a service provider, I compare all settings to my very simular project.

I've updated the libs path to the actual once of my CCSv6.2.0 installation, and now the error disappears.

Newer errors with my sinf32.asm files I could then solved with former answers.

Thanks for your help.
