Place Functions in RAM with SEGGER Linker
This article will show how to place a function into RAM with SEGGER Linker and Embedded Studio.
How to
- Create a symbol or function you want to place in RAM
- Open the SEGGER Linker script file and place the specific symol in RAM. This can be done e.g. as follows (or in one of the other ways documented ):
place in RAM1 {symbol MySymbol};
- This can be done by adding the following line to the remaining "initialize by copy entries".
initialize by copy { section .text.MySymbol, section .text.MySymbol.* };
Example project
The following example project will show an example implementation of such RAM function. A simple function Count() is created which is placed in RAM and executed.
Prerequisites
To be able to build and debug the project the following prerequisites must be met:
- SEGGER Embedded Studio V4.52c or later
- Any J-Link
- Cortex-M Trace Reference Board
