|
;* This module performs:
|
||||||
|
;* - Set the initial SP
|
||||||
|
;* - Set the initial PC == Reset_Handler
|
||||||
|
;* - Set the vector table entries with the exceptions ISR address
|
||||||
|
;* - Branches to __main in the C library (which eventually
|
||||||
|
;* calls main()).
|
||||||
|
;* After Reset the CortexM3 processor is in Thread mode,
|
||||||
|
;* priority is Privileged, and the Stack is set to Main.

;* address.
|
||||||
|
;* After Reset the Cortex-M3 processor is in Thread mode,
|
||||||
|
;* priority is Privileged, and the Stack is set to Main.

<h1>Changes to CMSIS version V1.20</h1>
|
||||||
|
|
||||||
|
<hr>
|
||||||
|
|
||||||
|
<h2>1. Removed CMSIS Middelware packages</h2>
|
||||||
|
<p>
|
||||||
|
CMSIS Middleware is on hold from ARM side until a agreement between all CMSIS partners is found.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>2. SystemFrequency renamed to SystemCoreClock</h2>
|
||||||
|
<p>
|
||||||
|
The variable name <strong>SystemCoreClock</strong> is more precise than <strong>SystemFrequency</strong>
|
||||||
|
because the variable holds the clock value at which the core is running.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>3. Changed startup concept</h2>
|
||||||
|
<p>
|
||||||
|
The old startup concept (calling SystemInit_ExtMemCtl from startup file and calling SystemInit
|
||||||
|
from main) has the weakness that it does not work for controllers which need a already
|
||||||
|
configuerd clock system to configure the external memory controller.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h3>Changed startup concept</h3>
|
||||||
|
<ul>
|
||||||
|
<li>
|
||||||
|
SystemInit() is called from startup file before <strong>premain</strong>.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<strong>SystemInit()</strong> configures the clock system and also configures
|
||||||
|
an existing external memory controller.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<strong>SystemInit()</strong> must not use global variables.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<strong>SystemCoreClock</strong> is initialized with a correct predefined value.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
Additional function <strong>void SystemCoreClockUpdate (void)</strong> is provided.<br>
|
||||||
|
<strong>SystemCoreClockUpdate()</strong> updates the variable <strong>SystemCoreClock</strong>
|
||||||
|
and must be called whenever the core clock is changed.<br>
|
||||||
|
<strong>SystemCoreClockUpdate()</strong> evaluates the clock register settings and calculates
|
||||||
|
the current core clock.
|
||||||
|
</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
|
||||||
|
<h2>4. Advanced Debug Functions</h2>
|
||||||
|
<p>
|
||||||
|
ITM communication channel is only capable for OUT direction. To allow also communication for
|
||||||
|
IN direction a simple concept is provided.
|
||||||
|
</p>
|
||||||
|
<ul>
|
||||||
|
<li>
|
||||||
|
Global variable <strong>volatile int ITM_RxBuffer</strong> used for IN data.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
Function <strong>int ITM_CheckChar (void)</strong> checks if a new character is available.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
Function <strong>int ITM_ReceiveChar (void)</strong> retrieves the new character.
|
||||||
|
</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
For detailed explanation see file <strong>CMSIS debug support.htm</strong>.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
|
||||||
|
<h2>5. Core Register Bit Definitions</h2>
|
||||||
|
<p>
|
||||||
|
Files core_cm3.h and core_cm0.h contain now bit definitions for Core Registers. The name for the
|
||||||
|
defines correspond with the Cortex-M Technical Reference Manual.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
e.g. SysTick structure with bit definitions
|
||||||
|

<h2>9. Open Points</h2>
|
||||||
|
<p>
|
||||||
|
Following points need to be clarified and solved:
|
||||||
|
</p>
|
||||||
|
<ul>
|
||||||
|
<li>
|
||||||
|
<p>
|
||||||
|
Equivalent C and Assembler startup files.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
Is there a need for having C startup files although assembler startup files are
|
||||||
|
very efficient and do not need to be changed?
|
||||||
|
<p/>
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<p>
|
||||||
|
Placing of HEAP in external RAM.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
It must be possible to place HEAP in external RAM if the device supports an
|
||||||
|
external memory controller.
|
||||||
|
</p>
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<p>
|
||||||
|
Placing of STACK /HEAP.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
STACK should always be placed at the end of internal RAM.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
If HEAP is placed in internal RAM than it should be placed after RW ZI section.
|
||||||
|
</p>
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<p>
|
||||||
|
Removing core_cm3.c and core_cm0.c.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
On a long term the functions in core_cm3.c and core_cm0.c must be replaced with
|
||||||
|
appropriate compiler intrinsics.
|
||||||
|
</p>
|
||||||
|
</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|

<h1>CMSIS Debug Support</h1>

|
|

<hr>
|
||||||
|
|
||||||
|
<h2>Cortex-M3 ITM Debug Access</h2>
|
||||||
|
<p>
|
||||||
|
The Cortex-M3 incorporates the Instrumented Trace Macrocell (ITM) that provides together with
|
||||||
|
the Serial Viewer Output trace capabilities for the microcontroller system. The ITM has
|
||||||
|
32 communication channels which are able to transmit 32 / 16 / 8 bit values; two ITM
|
||||||
|
communication channels are used by CMSIS to output the following information:
|
||||||
|
</p>
|
||||||
|
<ul>
|
||||||
|
<li>ITM Channel 0: used for printf-style output via the debug interface.</li>
|
||||||
|
<li>ITM Channel 31: is reserved for RTOS kernel awareness debugging.</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<h2>Debug IN / OUT functions</h2>
|
||||||
|
<p>CMSIS provides following debug functions:</p>
|
||||||
|
<ul>
|
||||||
|
<li>ITM_SendChar (uses ITM channel 0)</li>
|
||||||
|
<li>ITM_ReceiveChar (uses global variable)</li>
|
||||||
|
<li>ITM_CheckChar (uses global variable)</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<h3>ITM_SendChar</h3>
|
||||||
|
<p>
|
||||||
|
<strong>ITM_SendChar</strong> is used to transmit a character over ITM channel 0 from
|
||||||
|
the microcontroller system to the debug system. <br>
|
||||||
|
Only a 8 bit value is transmitted.
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
static __INLINE uint32_t ITM_SendChar (uint32_t ch)
|
||||||
|
{
|
||||||
|
/* check if debugger connected and ITM channel enabled for tracing */
|
||||||
|
if ((CoreDebug->DEMCR & CoreDebug_DEMCR_TRCENA) &&
|
||||||
|
(ITM->TCR & ITM_TCR_ITMENA) &&
|
||||||
|
(ITM->TER & (1UL << 0)) )
|
||||||
|
{
|
||||||
|
while (ITM->PORT[0].u32 == 0);
|
||||||
|
ITM->PORT[0].u8 = (uint8_t)ch;
|
||||||
|
}
|
||||||
|
return (ch);
|
||||||
|
}</pre>
|
||||||
|
|
||||||
|
<h3>ITM_ReceiveChar</h3>
|
||||||
|
<p>
|
||||||
|
ITM communication channel is only capable for OUT direction. For IN direction
|
||||||
|
a globel variable is used. A simple mechansim detects if a character is received.
|
||||||
|
The project to test need to be build with debug information.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
The globale variable <strong>ITM_RxBuffer</strong> is used to transmit a 8 bit value from debug system
|
||||||
|
to microcontroller system. <strong>ITM_RxBuffer</strong> is 32 bit wide to enshure a proper handshake.
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
extern volatile int ITM_RxBuffer; /* variable to receive characters */
|
||||||
|
</pre>
|
||||||
|
<p>
|
||||||
|
A dedicated bit pattern is used to determin if <strong>ITM_RxBuffer</strong> is empty
|
||||||
|
or contains a valid value.
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
#define ITM_RXBUFFER_EMPTY 0x5AA55AA5 /* value identifying ITM_RxBuffer is ready for next character */
|
||||||
|
</pre>
|
||||||
|
<p>
|
||||||
|
<strong>ITM_ReceiveChar</strong> is used to receive a 8 bit value from the debug system. The function is nonblocking.
|
||||||
|
It returns the received character or '-1' if no character was available.
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
static __INLINE int ITM_ReceiveChar (void) {
|
||||||
|
int ch = -1; /* no character available */
|
||||||
|
|
||||||
|
if (ITM_RxBuffer != ITM_RXBUFFER_EMPTY) {
|
||||||
|
ch = ITM_RxBuffer;
|

|
ITM_RxBuffer = ITM_RXBUFFER_EMPTY; /* ready for next character */
|
||||||
|
}
|
||||||
|
|
||||||
|
return (ch);
|
||||||
|
}
|
||||||
|
</pre>
|
||||||
|
|
||||||
|
<h3>ITM_CheckChar</h3>
|
||||||
|
<p>
|
||||||
|
<strong>ITM_CheckChar</strong> is used to check if a character is received.
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
static __INLINE int ITM_CheckChar (void) {
|
||||||
|
|
||||||
|
if (ITM_RxBuffer == ITM_RXBUFFER_EMPTY) {
|
||||||
|
return (0); /* no character available */
|

<h2>ITM Debug Support in uVision</h2>
|
||||||
|
<p>
|
||||||
|
uVision uses in a debug session the <strong>Debug (printf) Viewer</strong> window to
|
||||||
|
display the debug data.
|
||||||
|
</p>
|
||||||
|
<p>Direction microcontroller system -> uVision:</p>
|
||||||
|
<ul>
|
||||||
|
<li>
|
||||||
|
Characters received via ITM communication channel 0 are written in a printf style
|
||||||
|
to <strong>Debug (printf) Viewer</strong> window.
|
||||||
|
</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<p>Direction uVision -> microcontroller system:</p>
|
||||||
|
<ul>
|
||||||
|
<li>Check if <strong>ITM_RxBuffer</strong> variable is available (only performed once).</li>
|
||||||
|
<li>Read character from <strong>Debug (printf) Viewer</strong> window.</li>
|
||||||
|
<li>If <strong>ITM_RxBuffer</strong> empty write character to <strong>ITM_RxBuffer</strong>.</li>
|
||||||

</ul>
|
||||||
|
|
||||||
|
<p class="Note">Note</p>
|
||||||
|
<ul>
|

<h2>RTX Kernel awareness in uVision</h2>
|
||||||
|
<p>
|
||||||
|
uVision / RTX are using a simple and efficient solution for RTX Kernel awareness.
|
||||||
|
No format overhead is necessary.<br>
|
||||||
|
uVsion debugger decodes the RTX events via the 32 / 16 / 8 bit ITM write access
|
||||||
|
to ITM communication channel 31.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>Following RTX events are traced:</p>
|
||||||
|
<ul>
|
||||||
|
<li>Task Create / Delete event
|
||||||
|
<ol>
|
||||||
|
<li>32 bit access. Task start address is transmitted</li>
|
||||||
|
<li>16 bit access. Task ID and Create/Delete flag are transmitted<br>
|
||||||
|
High byte holds Create/Delete flag, Low byte holds TASK ID.
|
||||||
|
</li>
|
||||||
|
</ol>
|
||||||
|
</li>
|
||||||
|
<li>Task switch event
|
||||||
|
<ol>
|
||||||
|
<li>8 bit access. Task ID of current task is transmitted</li>
|
||||||
|
</ol>
|

<h1>Changes to CMSIS version V1.20</h1>
|
||||||
|
|
||||||
|
<hr>
|
||||||
|
|
||||||
|
<h2>1. Removed CMSIS Middelware packages</h2>
|
||||||
|
<p>
|
||||||
|
CMSIS Middleware is on hold from ARM side until a agreement between all CMSIS partners is found.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>2. SystemFrequency renamed to SystemCoreClock</h2>
|
||||||
|
<p>
|
||||||
|
The variable name <strong>SystemCoreClock</strong> is more precise than <strong>SystemFrequency</strong>
|
||||||
|
because the variable holds the clock value at which the core is running.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>3. Changed startup concept</h2>
|
||||||
|
<p>
|
||||||
|
The old startup concept (calling SystemInit_ExtMemCtl from startup file and calling SystemInit
|
||||||
|
from main) has the weakness that it does not work for controllers which need a already
|
||||||
|
configuerd clock system to configure the external memory controller.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h3>Changed startup concept</h3>
|
||||||
|
<ul>
|
||||||
|
<li>
|
||||||
|
SystemInit() is called from startup file before <strong>premain</strong>.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<strong>SystemInit()</strong> configures the clock system and also configures
|
||||||
|
an existing external memory controller.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<strong>SystemInit()</strong> must not use global variables.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<strong>SystemCoreClock</strong> is initialized with a correct predefined value.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
Additional function <strong>void SystemCoreClockUpdate (void)</strong> is provided.<br>
|
||||||
|
<strong>SystemCoreClockUpdate()</strong> updates the variable <strong>SystemCoreClock</strong>
|
||||||
|
and must be called whenever the core clock is changed.<br>
|
||||||
|
<strong>SystemCoreClockUpdate()</strong> evaluates the clock register settings and calculates
|
||||||
|
the current core clock.
|
||||||
|
</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
|
||||||
|
<h2>4. Advanced Debug Functions</h2>
|
||||||
|
<p>
|
||||||
|
ITM communication channel is only capable for OUT direction. To allow also communication for
|
||||||
|
IN direction a simple concept is provided.
|
||||||
|
</p>
|
||||||
|
<ul>
|
||||||
|
<li>
|
||||||
|
Global variable <strong>volatile int ITM_RxBuffer</strong> used for IN data.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
Function <strong>int ITM_CheckChar (void)</strong> checks if a new character is available.
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
Function <strong>int ITM_ReceiveChar (void)</strong> retrieves the new character.
|
||||||
|
</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
For detailed explanation see file <strong>CMSIS debug support.htm</strong>.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
|
||||||
|
<h2>5. Core Register Bit Definitions</h2>
|
||||||
|
<p>
|
||||||
|
Files core_cm3.h and core_cm0.h contain now bit definitions for Core Registers. The name for the
|
||||||
|
defines correspond with the Cortex-M Technical Reference Manual.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
e.g. SysTick structure with bit definitions
|
||||||
|

<h2>7. DoxyGen Tags</h2>
|
||||||
|
<p>
|
||||||
|
DoxyGen tags in files core_cm3.[c,h] and core_cm0.[c,h] are reworked to create proper documentation
|
||||||
|
using DoxyGen.
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<h2>8. Folder Structure</h2>
|
||||||
|
<p>
|
||||||
|
The folder structure is changed to differentiate the single support packages.

<h2>9. Open Points</h2>
|
||||||
|
<p>
|
||||||
|
Following points need to be clarified and solved:
|
||||||
|
</p>
|
||||||
|
<ul>
|
||||||
|
<li>
|
||||||
|
<p>
|
||||||
|
Equivalent C and Assembler startup files.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
Is there a need for having C startup files although assembler startup files are
|
||||||
|
very efficient and do not need to be changed?
|
||||||
|
<p/>
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<p>
|
||||||
|
Placing of HEAP in external RAM.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
It must be possible to place HEAP in external RAM if the device supports an
|
||||||
|
external memory controller.
|
||||||
|
</p>
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<p>
|
||||||
|
Placing of STACK /HEAP.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
STACK should always be placed at the end of internal RAM.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
If HEAP is placed in internal RAM than it should be placed after RW ZI section.
|
||||||
|
</p>
|
||||||
|
</li>
|
||||||
|
<li>
|
||||||
|
<p>
|
||||||
|
Removing core_cm3.c and core_cm0.c.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
On a long term the functions in core_cm3.c and core_cm0.c must be replaced with
|
||||||
|
appropriate compiler intrinsics.
|
||||||
|
</p>
|
||||||
|
</li>
|
||||||
|
</ul>
|
||||||
|
|
||||||
|
|
||||||
|
<h2>10. Limitations</h2>
|
||||||
|
<p>
|
||||||
|
The following limitations are not covered with the current CMSIS version:
|
||||||
|
</p>
|
||||||
|
<ul>
|
||||||
|
<li>
|
||||||

|
</li>
|
||||||
|
<li>
|
||||||
|

</li>
|
||||||
|
<li>
|
||||||
|
No <strong>Tasking</strong> projects are provided yet.
|
||||||
