/* in an "int" data type vary between microprocessor architectures and */
/* even C compilers for the same microprocessor. ThreadX does not */

/* own special types that can be mapped to actual data types by this */
/* file to guarantee consistency in the interface and functionality. */

Microsoft's Azure RTOS ThreadX for Cortex-M4
Using the AC6 Tools
1. Import the ThreadX Projects
In order to build the ThreadX library and the ThreadX demonstration, first import
the 'tx' and 'sample_threadx' projects (located in the "example_build" directory)
into your DS workspace.
2. Building the ThreadX run-time Library
Building the ThreadX library is easy; simply right-click the Eclipse project
"tx" and then select the "Build Project" button. You should now observe the compilation
and assembly of the ThreadX library. This project build produces the ThreadX
library file tx.a.
3. Demonstration System
The ThreadX demonstration is designed to execute under the DS debugger on the
MPS2_Cortex_M4 Bare Metal simulator.
Building the demonstration is easy; simply right-click the Eclipse project
"sample_threadx" and then select the "Build Project" button. You should now observe
the compilation and assembly of the ThreadX demonstration. This project build produces
the ThreadX library file sample_threadx.axf. Next, expand the demo ThreadX project folder
in the Project Explorer window, right-click on the 'cortex-m4_tx.launch' file, click
'Debug As', and then click 'cortex-m4_tx' from the submenu. This will cause the
debugger to load the sample_threadx.axf ELF file and run to main. You are now ready
to execute the ThreadX demonstration.
4. System Initialization
The entry point in ThreadX for the Cortex-M4 using AC6 tools uses the standard AC6
Cortex-M4 reset sequence. From the reset vector the C runtime will be initialized.
The ThreadX tx_initialize_low_level.S file is responsible for setting up
various system data structures, the vector area, and a periodic timer interrupt
source.
In addition, _tx_initialize_low_level determines the first available
address for use by the application, which is supplied as the sole input
parameter to your application definition function, tx_application_define.
5. Register Usage and Stack Frames
The following defines the saved context stack frames for context switches
that occur as a result of interrupt handling or from thread-level API calls.
All suspended threads have the same stack frame in the Cortex-M4 version of
ThreadX. The top of the suspended thread's stack is pointed to by
tx_thread_stack_ptr in the associated thread control block TX_THREAD.
Non-FPU Stack Frame:
Stack Offset Stack Contents
0x00 LR Interrupted LR (LR at time of PENDSV)
0x04 r4
0x08 r5
0x0C r6
0x10 r7

6. Improving Performance
The distribution version of ThreadX is built without any compiler optimizations.
This makes it easy to debug because you can trace or set breakpoints inside of
ThreadX itself. Of course, this costs some performance. To make it run faster,
you can change the build_threadx.bat file to remove the -g option and enable
all compiler optimizations.
In addition, you can eliminate the ThreadX basic API error checking by
compiling your application code with the symbol TX_DISABLE_ERROR_CHECKING
defined.
7. Interrupt Handling
ThreadX provides complete and high-performance interrupt handling for Cortex-M4
targets. There are a certain set of requirements that are defined in the
following sub-sections:
7.1 Vector Area
The Cortex-M4 vectors start at the label __tx_vectors or similar. The application may modify
the vector area according to its needs. There is code in tx_initialize_low_level() that will
configure the vector base register.
7.2 Managed Interrupts
ISRs can be written completely in C (or assembly language) without any calls to
_tx_thread_context_save or _tx_thread_context_restore. These ISRs are allowed access to the
ThreadX API that is available to ISRs.
ISRs written in C will take the form (where "your_C_isr" is an entry in the vector table):
void your_C_isr(void)
{
/* ISR processing goes here, including any needed function calls. */
}
ISRs written in assembly language will take the form:
.global your_assembly_isr
.thumb_func
your_assembly_isr:
; VOID your_assembly_isr(VOID)
; {
PUSH {r0, lr}
;
; /* Do interrupt handler work here */
; /* BL <your interrupt routine in C> */
POP {r0, lr}
BX lr
; }
Note: the Cortex-M4 requires exception handlers to be thumb labels, this implies bit 0 set.
To accomplish this, the declaration of the label has to be preceded by the assembler directive
.thumb_func to instruct the linker to create thumb labels. The label __tx_IntHandler needs to
be inserted in the correct location in the interrupt vector table. This table is typically
located in either your runtime startup file or in the tx_initialize_low_level.S file.
8. FPU Support
ThreadX for Cortex-M4 supports automatic ("lazy") VFP support, which means that applications threads
can simply use the VFP and ThreadX automatically maintains the VFP registers as part of the thread
context. If saving the context of the FPU registers is needed, the ThreadX library should be re-built
with TX_ENABLE_FPU_SUPPORT defined.
9. Revision History
For generic code revision information, please refer to the readme_threadx_generic.txt
file, which is included in your distribution. The following details the revision
information associated with this specific port of ThreadX:
06/30/2020 Initial ThreadX 6.0.1 version for Cortex-M4 using AC6 tools.
