STM CircleOS forum / Can't compile to fit in RAM

dianna.liu · 2009-06-11 21:46:05

I have a Primer2 with the STM32F103VET6. When I compile my program, "theProPowerTest" in Ride7, I get:
theProPowerTest.elf section .bss will not fit in region RAM
and
ld.exe: region RAM overflowed by 6748 bytes
Upon opening the .elf.ld file, it shows that it tries to include
STM32F103_32K_32K_FLASH.ld"

The part I have should be for a 64K part, but I don't even see a 64K option in the /lib directory. Has anyone run into this problem? Did I miss some files somehow?
Thanks

Oh, and to clarify, I tried modifiying the .elf.ld file to STM32F103_32K_64K_Flash but it keeps on reverting back to the 32K when I rebuild.

In the linker option, you will find file the name of the LD file (script) you are using. You have to open this file and to modify the RAM size.

I apologize... I was wrong (I thought you were working on an application based on CircleOS).
Crt0.ld from the LIB\ARM directory is not used. The default script is generated automatically, and it includes one of the file named "STM32F103_... .LD", depending on your configuration.
If you want to remove the 32KB limitation, the simplest way consists in selecting 'NO' for the option "Linker | Scripts | Starter script limitation".
