STM CircleOS forum / section .text will not fit in region FLASH

tybos · 2007-11-17 13:30:01

Hi everyone,

I started to try to make something fun from the Primer but I won't tell you what !!
My problem is that when I try to build my project, build fails because "section .text will not fit in region FLASH" and "region FLASH overflowed by 28 bytes" whereas my project takes "only" less than 6000 bytes for text section, 3100 for data ...
My Primer is a Pro one, so I'm far from the 128KB ...
My project uses CircleOS 1.6 so this only takes less than 40 KB ...
Are there some compiling options or anything else that could genrate such error ?

Thank you by advance ...

Open the circle_App.ld file in your project directory. Look at the memory spaces definitions.
One (128KB-16KB for Flash) is commented, and the second (only 8KB for the FLASH) is enabled. If you activate the first definition, you will remove the limitation in the linker.

Thank you for your quick answer !!
I wasn't expected any answer before monday !
Don't tell me you're working on Saturday ...
Anyway, have a nice week end.

I'm having this same problem, and both options seem to only allocate 8K for flash?

What seems to be the relevant part of the .ld file:

/* Memory Spaces Definitions */
/*
MEMORY
{
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 16K
FLASH (rx) : ORIGIN = 0x8006000, LENGTH = 8K
FLASHB1 (rx) : ORIGIN = 0x00000000, LENGTH = 0
EXTMEMB0 (rx) : ORIGIN = 0x00000000, LENGTH = 0
EXTMEMB1 (rx) : ORIGIN = 0x00000000, LENGTH = 0
EXTMEMB2 (rx) : ORIGIN = 0x00000000, LENGTH = 0
EXTMEMB3 (rx) : ORIGIN = 0x00000000, LENGTH = 0
}
*/
MEMORY
{
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 16K
FLASHB1 (r) : ORIGIN = 0x8000000, LENGTH = 0x0006000
FLASH (rx) : ORIGIN = 0x8006000, LENGTH = 8K
EXTMEMB0 (rx) : ORIGIN = 0x00000000, LENGTH = 0
EXTMEMB1 (rx) : ORIGIN = 0x00000000, LENGTH = 0
EXTMEMB2 (rx) : ORIGIN = 0x00000000, LENGTH = 0
EXTMEMB3 (rx) : ORIGIN = 0x00000000, LENGTH = 0
}

Thanks for any help.

In the second part:
FLASH (rx) : ORIGIN = 0x8006000, LENGTH = 8K
you should replace 8K by 104K (128-24):
FLASH (rx) : ORIGIN = 0x8006000, LENGTH = 104K
