Concerto M3 Boot Support
The Boot module supports boot initialization for the Concerto M3 core.
A special boot init function is created based on the configuration
settings for this module. This function is hooked into the
xdc.runtime.Reset.fxns[] array and called very early at boot time (prior
to cinit processing).

DETAILS
The Boot module supports boot initialization for the Concerto M3 core.
A special boot init function is created based on the configuration
settings for this module. This function is hooked into the
xdc.runtime.Reset.fxns[] array and called very early at boot time (prior
to cinit processing).
The code to support the boot module is placed in a separate section
named
".text:.bootCodeSection" to allow placement of this section in
the linker .cmd file if necessary. This section is a subsection of the
".text" section so this code will be placed into the .text section unless
explicitly placed, either through
Program.sectMap or through a linker
command file.
config Boot_configureClocks // module-wide |

Clock configuration flag, default is false
extern const Bool Boot_configureClocks;
DETAILS
Set to true to configure the PLL and system and M3 subsystem clock
dividers.

config Boot.configureClocks // module-wide |
![](../../../../../Arrow_up.png) |
Clock configuration flag, default is false
XDCscript usage |
meta-domain |
Boot.configureClocks = Bool false;
DETAILS
Set to true to configure the PLL and system and M3 subsystem clock
dividers.
C SYNOPSIS
metaonly config Boot.M3SSDIVSEL // module-wide |
![](../../../../../Arrow_up.png) |
M3 Subsystem Clock Divider (M3SSDIVSEL) value
XDCscript usage |
meta-domain |
metaonly config Boot.OSCCLK // module-wide |
![](../../../../../Arrow_up.png) |
OSCCLK input frequency to PLL, in MHz. Default is 20 MHz
XDCscript usage |
meta-domain |
DETAILS
This is the frequency of the oscillator clock (OSCCLK) input to the
PLL.
metaonly config Boot.SPLLFMULT // module-wide |
![](../../../../../Arrow_up.png) |
System PLL Fractional Multiplier (SPLLFMULT) value
XDCscript usage |
meta-domain |
metaonly config Boot.SPLLIMULT // module-wide |
![](../../../../../Arrow_up.png) |
System PLL Integer Multiplier (SPLLIMULT) value
XDCscript usage |
meta-domain |
metaonly config Boot.SYSDIVSEL // module-wide |
![](../../../../../Arrow_up.png) |
System Clock Divider (SYSDIVSEL) value
XDCscript usage |
meta-domain |
metaonly config Boot.bootC28 // module-wide |
![](../../../../../Arrow_up.png) |
Initiate booting of the C28 processor. Default is false
XDCscript usage |
meta-domain |
Boot.bootC28 = Bool false;
DETAILS
Set to true to enable the M3 to initiate boot of the C28.
If enabled, this will occur after the optional clock configuration
step, enabled by
configureClocks.
metaonly config Boot.bootFromFlash // module-wide |
![](../../../../../Arrow_up.png) |
Boot from FLASH flag. Default is true
XDCscript usage |
meta-domain |
Boot.bootFromFlash = Bool true;
DETAILS
Set to true to enable booting the M3 from FLASH.
metaonly config Boot.limpAbortFunction // module-wide |
![](../../../../../Arrow_up.png) |
Function to be called when Limp mode is detected
XDCscript usage |
meta-domain |
Boot.limpAbortFunction = Fxn undefined;
DETAILS
This function is called when the Boot module is about to configure
the PLL, but finds the device operating in Limp mode (i.e., the mode
when a missing OSCCLK input has been detected).
If this function is not specified by the application, a default
function will be used, which spins in an infinite loop.
metaonly config Boot.rovViewInfo // module-wide |
![](../../../../../Arrow_up.png) |
XDCscript usage |
