/** \brief Declaration of the actual parameter buffer that this module manages.
* \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:
* * IAR EWARM:
* https://www.iar.com/support/tech-notes/compiler/
* linker-error-for-absolute-located-variable/
* * Keil MDK:
* http://www.keil.com/support/docs/3480.htm

/** \brief Declaration of the actual parameter buffer that this module manages.
* \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:
* * IAR EWARM:
* https://www.iar.com/support/tech-notes/compiler/
* linker-error-for-absolute-located-variable/
* * Keil MDK:

* 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:
* * IAR EWARM:
* https://www.iar.com/support/tech-notes/compiler/
* linker-error-for-absolute-located-variable/

/** \brief Declaration of the actual parameter buffer that this module manages.
* \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:
* * IAR EWARM:
* https://www.iar.com/support/tech-notes/compiler/
* linker-error-for-absolute-located-variable/
* * Keil MDK:

* \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:
* * IAR EWARM:
* https://www.iar.com/support/tech-notes/compiler/
* linker-error-for-absolute-located-variable/
* * Keil MDK:

* \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:
* * IAR EWARM:
* https://www.iar.com/support/tech-notes/compiler/
* linker-error-for-absolute-located-variable/
* * Keil MDK:
