|

* \warning For the shared RAM parameters to work properly for sharing information
|
||||
* between the bootloader and user program, it is important that this
|
||||
* variable is linked to the exact same RAM address in both the bootloader
|
||||
* and the user program. Additionally, it should be configured such that the
|
||||
* C-startup code does NOT zero its contents during system initialization. This
|
||||
* is the code that runs in the reset event handler, before function main() is
|
||||
* called.
|
||||
* For GCC based embedded toolchains, the solution is to assign this variable
|
||||
* to a custom section, in this case called ".shared". Then in the linker
|
||||
* script, add the following to the SECTIONS:
|
||||
*
|
||||
* .shared (NOLOAD) :
|
||||
* {
|
||||
* . = ALIGN(4);
|
||||
* _sshared = .;
|
||||
* __shared_start__ = _sshared;
|
||||
* *(.shared)
|
||||
* *(.shared.*)
|
||||
* KEEP(*(.shared))
|
||||
* . = ALIGN(4);
|
||||
* _eshared = .;
|
||||
* __shared_end__ = _eshared;
|
||||
* } >SHARED
|
||||
*
|
||||
* Next, add a new MEMORY entry for SHARED at the start of RAM and reduce
|
||||
* the length of the remaining RAM:
|
||||
*
|
||||
* SHARED (xrw) : ORIGIN = 0x200000C0, LENGTH = 64
|
||||
* RAM (xrw) : ORIGIN = 0x20000100, LENGTH = 32K - 192 - 64
|
||||
*
|
||||
* Note that the previous example is for an STM32F0 microcontroller where
|
||||
* the first 192 (0xC0) bytes in RAM are reserved for the user program
|
||||
* vector table.
|
||||
*
|
||||
* \remark This same approach can be applied with other toolchains such as Keil MDK
|
||||
* and IAR EWARM. Consult the compiler and linker user manuals of your
|
||||
* toolchain to find out how to place a RAM variable at a fixed memory address
|
||||
* and to prevent the C-startup code from zeroing its contents.
|
||||
* Here are a few links to get you started:
|
||||

* between the bootloader and user program, it is important that this

||||
* variable is linked to the exact same RAM address in both the bootloader
|
||||
* and the user program. Additionally, it should be configured such that the
|
||||
* C-startup code does NOT zero its contents during system initialization. This
|
||||
* is the code that runs in the reset event handler, before function main() is
|
||||
* called.
|
||||
* For GCC based embedded toolchains, the solution is to assign this variable
|
||||
* to a custom section, in this case called ".shared". Then in the linker
|
||||
* script, add the following to the SECTIONS:
|
||||
*
|
||||
* .shared (NOLOAD) :
|
||||
* {
|
||||
* . = ALIGN(4);
|
||||
* _sshared = .;
|
||||
* __shared_start__ = _sshared;
|
||||
* *(.shared)
|
||||
* *(.shared.*)
|
||||
* KEEP(*(.shared))
|
||||
* . = ALIGN(4);
|
||||
* _eshared = .;
|
||||
* __shared_end__ = _eshared;
|
||||
* } >SHARED
|
||||
*
|
||||
* Next, add a new MEMORY entry for SHARED at the start of RAM and reduce
|
||||
* the length of the remaining RAM:
|
||||
*
|
||||
* SHARED (xrw) : ORIGIN = 0x200000C0, LENGTH = 64
|
||||
* RAM (xrw) : ORIGIN = 0x20000100, LENGTH = 32K - 192 - 64
|
||||
*
|
||||
* Note that the previous example is for an STM32F0 microcontroller where
|
||||
* the first 192 (0xC0) bytes in RAM are reserved for the user program
|
||||
* vector table.
|
||||
*
|
||||
* \remark This same approach can be applied with other toolchains such as Keil MDK
|
||||
* and IAR EWARM. Consult the compiler and linker user manuals of your
|
||||
* toolchain to find out how to place a RAM variable at a fixed memory address
|
||||
* and to prevent the C-startup code from zeroing its contents.
|
||||
* Here are a few links to get you started:
|
||||
