Functions that are executed in RAM should reside in a separate source module. Using the 'Options for File' dialog you can simply change the 'Code / Const' area of a module to a memory space in physical RAM. Available memory areas are declared in the 'Target' tab of the Options for Target' dialog. *** ICCARM Compiler *** ----------------------- [..] RAM functions are defined using a specific toolchain keyword "__ramfunc". *** GNU Compiler *** -------------------- [..] RAM functions are defined using a specific toolchain attribute "__attribute__((section(".RamFunc")))". @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2016 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
