@code
This driver provides functions to configure and program the Flash memory of all
STM8S devices.
It includes as well functions that can be either executed from RAM or not, and
other functions that must be executed from RAM otherwise useless.
The table below lists the functions that can be executed from RAM.
+--------------------------------------------------------------------------------|
| Functions prototypes | RAM execution | Comments |
---------------------------------------------------------------------------------|
| | Mandatory in case of block | Can be executed |
| FLASH_WaitForLastOperation | Operation: | from Flash in case |
| | - Block programming | of byte and word |
| | - Block erase | Operations |
|--------------------------------------------------------------------------------|
| FLASH_ProgramBlock | Exclusively | useless from Flash |
|--------------------------------------------------------------------------------|
| FLASH_EraseBlock | Exclusively | useless from Flash |
|--------------------------------------------------------------------------------|
To be able to execute functions from RAM several steps have to be followed.
These steps may differ from one toolchain to another.
A detailed description is available below within this driver.
You can also refer to the FLASH examples provided within the
STM8S_StdPeriph_Lib package.

@code
All the functions defined below must be executed from RAM exclusively, except
for the FLASH_WaitForLastOperation function which can be executed from Flash.
Steps of the execution from RAM differs from one toolchain to another:
- For Cosmic Compiler:
1- Define a segment FLASH_CODE by the mean of " #pragma section (FLASH_CODE)".
This segment is defined in the stm8s_flash.c file.
2- Uncomment the "#define RAM_EXECUTION (1)" line in the stm8s.h file,
or define it in Cosmic compiler preprocessor to enable the FLASH_CODE segment
definition.
3- In STVD Select Project\Settings\Linker\Category "input" and in the RAM section
add the FLASH_CODE segment with "-ic" options.
4- In main.c file call the _fctcpy() function with first segment character as
parameter "_fctcpy('F');" to load the declared moveable code segment
(FLASH_CODE) in RAM before execution.
5- By default the _fctcpy function is packaged in the Cosmic machine library,
so the function prototype "int _fctcopy(char name);" must be added in main.c
file.
- For Raisonance Compiler
1- Use the inram keyword in the function declaration to specify that it can be
executed from RAM.
This is done within the stm8s_flash.c file, and it's conditioned by
RAM_EXECUTION definition.
2- Uncomment the "#define RAM_EXECUTION (1)" line in the stm8s.h file, or
define it in Raisonance compiler preprocessor to enable the access for the
inram functions.
3- An inram function code is copied from Flash to RAM by the C startup code.
In some applications, the RAM area where the code was initially stored may be
erased or corrupted, so it may be desirable to perform the copy again.
Depending on the application memory model, the memcpy() or fmemcpy() functions
should be used to perform the copy.
' In case your project uses the SMALL memory model (code smaller than 64K),
memcpy()function is recommended to perform the copy
' In case your project uses the LARGE memory model, functions can be
everywhere in the 24-bits address space (not limited to the first 64KB of
code), In this case, the use of memcpy() function will not be appropriate,
you need to use the specific fmemcpy() function (which copies objects with
24-bit addresses).
- The linker automatically defines 2 symbols for each inram function:
' __address__functionname is a symbol that holds the Flash address
where the given function code is stored.
' __size__functionname is a symbol that holds the function size in bytes.
And we already have the function address (which is itself a pointer)
4- In main.c file these two steps should be performed for each inram function:
' Import the "__address__functionname" and "__size__functionname" symbols
as global variables:
extern int __address__functionname; // Symbol holding the flash address
extern int __size__functionname; // Symbol holding the function size
' In case of SMALL memory model use, Call the memcpy() function to copy the
inram function to the RAM destination address:
memcpy(functionname, // RAM destination address
(void*)&__address__functionname, // Flash source address
(int)&__size__functionname); // Code size of the function
' In case of LARGE memory model use, call the fmemcpy() function to copy
the inram function to the RAM destination address:
memcpy(functionname, // RAM destination address
(void @far*)&__address__functionname, // Flash source address
(int)&__size__functionname); // Code size of the function
- For IAR Compiler:
1- Use the __ramfunc keyword in the function declaration to specify that it
can be executed from RAM.
This is done within the stm8s_flash.c file, and it's conditioned by
RAM_EXECUTION definition.
2- Uncomment the "#define RAM_EXECUTION (1)" line in the stm8s.h file, or
define it in IAR compiler preprocessor to enable the access for the
__ramfunc functions.
- Note:
1- Ignore the IAR compiler warnings, these warnings don't impact the FLASH Program/Erase
operations.
The code performing the Flash Program/erase must be executed from RAM; the variables
initializations don't necessary require the execution from RAM, only CR2/NCR2 registers
configuration and data programing must be executed from RAM.
2- These warnings depends on IAR compiler: as the code generation is made using many
runtime library functions to keep code size to a minimum.
3- It is recommended to use High Speed Optimization with IAR (-Ohs), in order
to reduce the runtime library calls in the generated code.
The FLASH examples given within the STM8S_StdPeriph_Lib package, details all
the steps described above.
