The SimpleLink SDKs provide peripheral driver and WiFi libraries
|
|
and hardware register access header files for the Texas Instruments
|
|
SimpleLink SoCs.
|
|
|
|
For an explanation of the SimpleLink family SDK directory structure, see:
|
|
http://dev.ti.com/tirex/content/simplelink_cc32xx_sdk_2_40_01_01/docs/simplelink_mcu_sdk/Users_Guide.html#directory-structure
|
|
|
|
1. CC13x2/26x2 SDK
|
|
|
|
The current version supported in Zephyr is the SimpleLink CC13x2 and CC26x2 SDK
|
|
4.10.00.78, downloaded from:
|
|
|
|
http://www.ti.com/tool/simplelink-cc13x2-26x2-sdk
|
|
|
|
The driver library source is copied from the SDK, as follows:
|
|
|
|
EXT_DIR=$HOME/hal_ti/simplelink/source/ti
|
|
pushd simplelink_cc13x2_26x2_sdk_4_10_00_78/source/ti
|
|
find devices/cc13x2_cc26x2/{driverlib,inc,rf_patches} -depth -name '*.[c|h]' -print0 | cpio --null -pvdm $EXT_DIR
|
|
find devices/cc13x2_cc26x2/startup_files -depth -name ccfg.c -print0 | cpio --null -pvd $EXT_DIR
|
|
cp -r drivers/power/* $EXT_DIR/drivers/power/.
|
|
mkdir $EXT_DIR/drivers/temperature
|
|
cp -r drivers/temperature/* $EXT_DIR/drivers/temperature/.
|
|
cp drivers/Temperature.* $EXT_DIR/drivers/.
|
|
mkdir $EXT_DIR/drivers/rf
|
|
cp drivers/rf/RF.h $EXT_DIR/drivers/rf/.
|
|
cp drivers/rf/RFCC26X2.h $EXT_DIR/drivers/rf/.
|
|
cp drivers/rf/RFCC26X2_multiMode.c $EXT_DIR/drivers/rf/.
|
|
find $EXT_DIR/devices/cc13x2_cc26x2 -name '*.[c|h]' -exec dos2unix {} \;
|
|
find $EXT_DIR/drivers/power -name '*.[c|h]' -exec dos2unix {} \;
|
|
find $EXT_DIR/drivers/rf -name '*.[c|h]' -exec dos2unix {} \;
|
|
find $EXT_DIR/drivers/temperature -name '*.[c|h]' -exec dos2unix {} \;
|
|
popd
|
|
|
|
The source file devices/cc13x2_cc26x2/startup_files/ccfg.c has been
|
|
modified to use the appropriate sections when linking.
|
|
|
|
TI provides the driver library functions burned into ROM at the factory,
|
|
or updated via a service pack patch, thus saving application code space.
|
|
|
|
After setting CONFIG_HAS_CC13X2_CC26X2_SDK=y in Kconfig, most of the
|
|
peripheral driver library functions will be accessible from ROM.
|
|
|
|
2. CC32xx SDK
|
|
|
|
The current version supported in Zephyr is the SimpleLink CC32xx SDK
|
|
4.10.00.07, downloaded from:
|
|
|
|
http://www.ti.com/tool/download/simplelink-cc32xx-sdk
|
|
|
|
Source files from select subdirectories are copied from the
|
|
source/ti/ subdirectory of the SDK installation, as follows:
|
|
|
|
EXT_DIR=$HOME/hal_ti/simplelink/source/ti
|
|
find devices -not -path '*/\.*' -name '*.[c|h]' | \
|
|
cpio -pdm $EXT_DIR
|
|
find drivers -name '*.[c|h]' | \
|
|
cpio -pdm $EXT_DIR
|
|
find net -maxdepth 1 -name '*.[c|h]' | cpio -pdm $EXT_DIR
|
|
cd $EXT_DIR
|
|
find . -name '*.[c|h]' -exec chmod 664 {} \;
|
|
find $EXT_DIR/devices/cc32xx -name '*.[c|h]' -exec dos2unix {} \;
|
|
find $EXT_DIR/drivers -name '*.[c|h]' -exec dos2unix {} \;
|
|
|
|
When updating to a new SDK, a comparison of the files in the 'devices'
|
|
and 'drivers' directories as copied above should be performed to pick up
|
|
any new changes. Header files in source/ti/drivers/dpl should also be
|
|
compared, both to pick up new changes and to ensure any modifications
|
|
that were previously made are kept in place after the update if
|
|
appropriate.
|
|
|
|
In addition, some files in the source/ti/drivers/net/wifi/porting
|
|
directory may need to be updated: notably user.h, cc_pal.c and cc_pal.h.
|
|
Files in kernel/zephyr/dpl copied verbatim from kernel/nortos/dpl in the
|
|
SDK, such as QueueP.h, QueueP_nortos.c and SwiP_nortos.c, should be
|
|
compared to see if new changes have been introduced.
|
|
|
|
Note: TI provides the driver library functions burned into ROM at the factory,
|
|
or updated via a service pack patch, thus saving application code space.
|
|
|
|
Calling driverlib APIs prefixed by "MAP_" will vector to those functions
|
|
already existing in ROM.
|
|
|
|
After setting CONFIG_HAS_CC3220SDK=y in Kconfig, most of the
|
|
peripheral driver library functions will be accessible from ROM,
|
|
except for some functions in the following modules, which are
|
|
compiled in the Kbuild file:
|
|
- driverlib/pin.c
|
|
- driverlib/utils.c
|
|
- driverlib/prcm.c
|
|
|
|
Setting CONFIG_SIMPLELINK_HOST_DRIVER=y builds the SimpleLink Host
|
|
Driver, which communicates over dedicated SPI to the
|
|
network coprocessor.
|
|
|
|
2. MSP432 SDK
|
|
|
|
The current version supported in Zephyr is MSP432 SDK V1.50.00.12, downloaded
|
|
from:
|
|
|
|
http://www.ti.com/tool/simplelink-msp432-sdk
|
|
|
|
Files in source/ti/devices/msp432p4xx/driverlib/ and inc/ are copied from
|
|
a Linux SDK installation (without modification).
|
|
|
|
TI provides the driver library functions burned into ROM at the factory,
|
|
or updated via a service pack patch, thus saving application code space.
|
|
|
|
Calling driverlib APIs prefixed by "MAP_" will vector to those functions
|
|
already existing in ROM.
|
|
|
|
After setting CONFIG_HAS_MSP432P4XXSDK=y in Kconfig, most of the
|
|
peripheral driver library functions will be accessible from ROM.
