/*
* 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.
