STM8 Linker: text size overflow ... just in Release ... not in Debug

Hello everyone!

Currently I'm switching from an Atmel ATTiny to a STM8 microcontroller and so I'm evaluating different IDEs and compilers. I started with a combination of the ST Visual Development and the COSMIC STM8 Compiler (Cosmic CXSTM8 Special Edition 4.4.4). So far, it worked quite nice. I migrated the ATTiny code step by step to the STM environment. I always used both, the Debug builds and Release builds on my target. But at one point, there seems to be a limit to the Release build:

Running Linker

clnk -l''C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8\Lib'' -o Release\stm8s003.sm8 Release\stm8s003.lkf

#error clnk Release\stm8s003. segment .text size overflow (164)

The command: ''clnk -l''C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8\Lib'' -o Release\stm8s003.sm8 Release\stm8s003.lkf '' has failed, the returned value is: 1

exit code=1.

When I remove code, the number (164) reduces. The Debug build is ok without any problems. Is there any limit to the linker? or does anyone have a hint?

Thanks!

Chris

Ok, damn, - it was just the code size.

I switched the optimization to ''minimize code size'' and now it works :)

...Also ''split functions into separate sections'' works

But how can I see how big my code is? Is there a statistic somewhere? - In the programmer window I can just see how big the .s19 files are... and in my case they are always same size.

the map file created by the linker contains all the information you need about code size and memory usage.
