STM32: GCC linker script changing from STM32F100 to STM32F103

[rhodges]

I am getting into STM32 land now

I have installed my ARM tools and I have built a demo program, looked at the startup and main code, and am looking forward to working with it.

The example code is from Dr. Geoffrey Brown and it has a linker script for the STM32F100 (128K Flash, 8K RAM). I have two boards witth STM32F103C8 (64K Flash, 20K RAM).

I copied his script and changed the memory section to:

Code: [Select]

MEMORY
{
  RAM (rwx)  : ORIGIN = 0x20000000, LENGTH = 20K
  FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 64K
}
Is this all I need to change? Thanks!

That depends on what else is in the linker script. Attach the complete file.

Okay, here is the whole thing. (If the attachment doesn't work, I will cut and paste it in.)

This is a well written linker script. Those changes should be sufficient.

I like the idea with stack size checker. I will borrow that for my scripts.
