* Using dynamic memory allocation requires to apply some changes to the linker file.
|
|
* ThreadX needs to pass a pointer to the first free memory location in RAM to the tx_application_define() function,
|
|
* using the "first_unused_memory" argument.
|
|
* This require changes in the linker files to expose this memory location.
|
|
* For EWARM add the following section into the .icf file:
|
|
place in RAM_region { last section FREE_MEM };
|
|
* For MDK-ARM
|
|
- either define the RW_IRAM1 region in the ".sct" file
|
|
- or modify the line below in "tx_initialize_low_level.S to match the memory region being used
|
|
LDR r1, =|Image$$RW_IRAM1$$ZI$$Limit|
|
|
|
|
* For STM32CubeIDE add the following section into the .ld file:
|
|
._threadx_heap :
|
|
{
|
|
. = ALIGN(8);
|
|
__RAM_segment_used_end__ = .;
|
|
. = . + 64K;
|
|
. = ALIGN(8);
|
|
} >RAM_D1 AT> RAM_D1
|
|
* The simplest way to provide memory for ThreadX is to define a new section, see ._threadx_heap above.
|
|
* In the example above the ThreadX heap size is set to 64KBytes.
|
|
* The ._threadx_heap must be located between the .bss and the ._user_heap_stack sections in the linker script.
|
|
* Caution: Make sure that ThreadX does not need more than the provided heap memory (64KBytes in this example).
|
|
* Read more in STM32CubeIDE User Guide, chapter: "Linker script".
|
|
|
|
* The "tx_initialize_low_level.S" should be also modified to enable the "USE_DYNAMIC_MEMORY_ALLOCATION" flag.
