1The SimpleLink SDKs provide peripheral driver and WiFi libraries
2and hardware register access header files for the Texas Instruments
3SimpleLink SoCs.

5For an explanation of the SimpleLink family SDK directory structure, see:

81. CC13x2/26x2 SDK
9
10The current version supported in Zephyr is the SimpleLink CC13x2 and CC26x2 SDK
114.10.00.78, downloaded from:
12
13 http://www.ti.com/tool/simplelink-cc13x2-26x2-sdk
14
15The driver library source is copied from the SDK, as follows:
16
17 EXT_DIR=$HOME/hal_ti/simplelink/source/ti
18 pushd simplelink_cc13x2_26x2_sdk_4_10_00_78/source/ti
19 find devices/cc13x2_cc26x2/{driverlib,inc,rf_patches} -depth -name '*.[c|h]' -print0 | cpio --null -pvdm $EXT_DIR
20 find devices/cc13x2_cc26x2/startup_files -depth -name ccfg.c -print0 | cpio --null -pvd $EXT_DIR
21 cp -r drivers/power/* $EXT_DIR/drivers/power/.
22 mkdir $EXT_DIR/drivers/temperature
23 cp -r drivers/temperature/* $EXT_DIR/drivers/temperature/.
24 cp drivers/Temperature.* $EXT_DIR/drivers/.
25 mkdir $EXT_DIR/drivers/rf
26 cp drivers/rf/RF.h $EXT_DIR/drivers/rf/.
27 cp drivers/rf/RFCC26X2.h $EXT_DIR/drivers/rf/.
28 cp drivers/rf/RFCC26X2_multiMode.c $EXT_DIR/drivers/rf/.
29 find $EXT_DIR/devices/cc13x2_cc26x2 -name '*.[c|h]' -exec dos2unix {} \;
30 find $EXT_DIR/drivers/power -name '*.[c|h]' -exec dos2unix {} \;
31 find $EXT_DIR/drivers/rf -name '*.[c|h]' -exec dos2unix {} \;
32 find $EXT_DIR/drivers/temperature -name '*.[c|h]' -exec dos2unix {} \;
33 popd
34
35The source file devices/cc13x2_cc26x2/startup_files/ccfg.c has been
36modified to use the appropriate sections when linking.
37
38TI provides the driver library functions burned into ROM at the factory,
39or updated via a service pack patch, thus saving application code space.
40
41After setting CONFIG_HAS_CC13X2_CC26X2_SDK=y in Kconfig, most of the
42peripheral driver library functions will be accessible from ROM.
43
442. CC32xx SDK
45
46The current version supported in Zephyr is the SimpleLink CC32xx SDK
474.10.00.07, downloaded from:
48
49 http://www.ti.com/tool/download/simplelink-cc32xx-sdk
50
51Source files from select subdirectories are copied from the
52source/ti/ subdirectory of the SDK installation, as follows:
53
54 EXT_DIR=$HOME/hal_ti/simplelink/source/ti
55 find devices -not -path '*/\.*' -name '*.[c|h]' | \
56 cpio -pdm $EXT_DIR
57 find drivers -name '*.[c|h]' | \
58 cpio -pdm $EXT_DIR
59 find net -maxdepth 1 -name '*.[c|h]' | cpio -pdm $EXT_DIR
60 cd $EXT_DIR
61 find . -name '*.[c|h]' -exec chmod 664 {} \;
62 find $EXT_DIR/devices/cc32xx -name '*.[c|h]' -exec dos2unix {} \;
63 find $EXT_DIR/drivers -name '*.[c|h]' -exec dos2unix {} \;
64
65When updating to a new SDK, a comparison of the files in the 'devices'
66and 'drivers' directories as copied above should be performed to pick up
67any new changes. Header files in source/ti/drivers/dpl should also be
68compared, both to pick up new changes and to ensure any modifications
69that were previously made are kept in place after the update if
70appropriate.
71
72In addition, some files in the source/ti/drivers/net/wifi/porting
73directory may need to be updated: notably user.h, cc_pal.c and cc_pal.h.
74Files in kernel/zephyr/dpl copied verbatim from kernel/nortos/dpl in the
75SDK, such as QueueP.h, QueueP_nortos.c and SwiP_nortos.c, should be
76compared to see if new changes have been introduced.
77
78Note: TI provides the driver library functions burned into ROM at the factory,
79or updated via a service pack patch, thus saving application code space.
80
81Calling driverlib APIs prefixed by "MAP_" will vector to those functions
82already existing in ROM.
83
84After setting CONFIG_HAS_CC3220SDK=y in Kconfig, most of the
85peripheral driver library functions will be accessible from ROM,
86except for some functions in the following modules, which are
87compiled in the Kbuild file:
88- driverlib/pin.c
89- driverlib/utils.c
90- driverlib/prcm.c
91
92Setting CONFIG_SIMPLELINK_HOST_DRIVER=y builds the SimpleLink Host
93Driver, which communicates over dedicated SPI to the
94network coprocessor.
95
962. MSP432 SDK
97
98The current version supported in Zephyr is MSP432 SDK V1.50.00.12, downloaded
99from:
100
101 http://www.ti.com/tool/simplelink-msp432-sdk
102
103Files in source/ti/devices/msp432p4xx/driverlib/ and inc/ are copied from
104a Linux SDK installation (without modification).
105
106TI provides the driver library functions burned into ROM at the factory,
107or updated via a service pack patch, thus saving application code space.
108
109Calling driverlib APIs prefixed by "MAP_" will vector to those functions
110already existing in ROM.
111
112After setting CONFIG_HAS_MSP432P4XXSDK=y in Kconfig, most of the
113peripheral driver library functions will be accessible from ROM.
