STM8S207 - Linker error ''Section boundary crossing''

[StefanHogg]

Hi together,

I'm writing a application for a STM8S207C8 (64k flash).Currently my code needs 50kB of the flash, what means that the ''magic'' address 0xFFFF is crossed. Therefore I use the compiler option ''+modsl'' (recommended by the compiler manual). This configuration works properly. Now I would like to use the power-on self-test functionality from the ST self-test library. Therefore I created the needed sections in linker file and mapped the call of ''STL_StartUp'' at my reset interrupt vector (as recommended by AN3181, corresponding to the ST self-test library). The bad fact is that with this new configuration I get the following linker error:

#error clnk Debug_Standard\sey-redesign.lkf:92 Debug_Standard\stm8s_stl_startup.o: section boundary crossing (.text:00c9) f__stext

I looked for this error code in the STM8 forum but I couldn't find a answer that would help me. I only found the hint to note the chapter ''Memory Models for code larger than 64K'' in the compiler manual. It recommends to use the compiler option ''+modsl''. This option I've already used. Additionally I found the hint to avoid the compiler options ''-gnc'' and ''+nocross''. These options were not used in my application. Do anyone of you have another idea how to avoid this linker error? Thanks, Stefan. I use following environment: IDE: ST Visual Develop (v4.3.1) Compiler: COSMIC CXSTM8 (v4.3.7) Content of the used linker file:
