Introduce the TI CC13xx/CC13x4 Wi-SUN FAN family as a supported
csmp-agent-lib target. The implementation uses SDK-only prebuilt
libraries (no external source repositories required); all Wi-SUN
MAC, Nanostack, and TLS symbols are supplied by the SDK's
maclib_secure, wisun_rn_mbed_ns_tls_lib, and wisun_ncp_lib
archives, selected automatically by SysConfig via
ti_utils_build_linker.cmd.genlibs.
Five LaunchPad variants are supported and built in a single
./build.sh ti_simplelink_wisun invocation by a BOARD_DIRS wildcard
over Vendors/TI/*/csmp_example_tirf/freertos/ticlang/. Adding a
new board requires only placing a directory there.
osal/ti_simplelink_wisun:
- osal_ti_simplelink_wisun.c: FreeRTOS/Nanostack OSAL implementation;
socket, thread, mutex, timer, and NV-storage bindings for CC13xx
- osal_platform_types.h: platform type definitions and mbed_tracef
forward declaration; guards main() in CsmpAgentLib_sample.c via
OSAL_TI_SIMPLELINK_WISUN so the library compiles without a duplicate
entry point when linked into the board firmware
- ti_simplelink_wisun.mak: SDK include paths for device headers,
FreeRTOS portable layer, Nanostack public API, mbedTLS, and NVOCMP;
supports CC13X4, CC13X2X7, CC13X2, and CC13X1 via DEVICE_FAMILY
sample/tlvs/ti_simplelink_wisun_tlvs.c:
- TI-specific TLV callbacks: wpanstatus, RPL, interface metrics,
firmware image info, and hardware description; reads live data
from Nanostack ws_management_api and nwk_stats_api
- g_tx_power_dbm: file-scoped variable set by application.c from
CONFIG_TRANSMIT_POWER; extern declaration removed from the shared
CsmpAgentLib_sample_tlvs.h to keep platform-specific symbols out
of the common header
Vendors/TI/application (shared across all boards):
- main.c / application.c: Wi-SUN border router node application;
initialises mesh_system, opens UDP socket to NMS, starts CSMP
agent task; sets g_tx_power_dbm from SysConfig CONFIG_TRANSMIT_POWER
- mbed_config_app.h / advanced_config.h: Wi-SUN PHY configuration
(FAN 1.1, North America 915 MHz, FH mode)
- wisun_certificates.h / ws_router_fan_cert_certificates.h: device
and CA certificate buffers for WPA2 network authentication
- defines/router.opts: compile-time CSMP options; NMS address set
via -DCSMP_AGENT_NMS_ADDRESS; device type OPENCSMP
Vendors/TI/<BOARD>/csmp_example_tirf:
- Five board configurations: LP_CC1312R7, LP_CC1352P7_1 (Cortex-M4F,
CC13X2X7) and LP_EM_CC1314R10, LP_EM_CC1354P10_1, LP_EM_CC1354P10_6
(Cortex-M33, CC13X4); each board carries only its board-specific
csmp_example.syscfg (--board target) and ticlang/makefile (CPU
flags, device include paths, linker command file)
- M4F boards: -mcpu=cortex-m4 -march=armv7e-m -mfpu=fpv4-sp-d16,
cc13x2x7_cc26x2x7.cmd, ARM_CM4F FreeRTOS port
- M33F boards: -mcpu=cortex-m33 -mfpu=fpv5-sp-d16,
cc13x4_cc26x4.cmd, ARM_CM33/non_secure FreeRTOS port
- genLibs: TI154Stack.genLibs = "none" removed from syscfg so
SysConfig emits prebuilt .a paths into genlibs; build previously
required compiling ~250 MAC/Nanostack/TLS source files from the
wisunfan development repo — now resolved entirely from SDK
ti_simplelink_wisun.target / sample/ti_simplelink_wisun.target:
- Root library target builds csmp_agent_lib_ti_simplelink_wisun.a
using TI ARM Clang; board target loops over BOARD_DIRS and invokes
each board makefile with CSMP_AGENT_LIB_INSTALL_DIR and SDK paths
- Tool paths (SYSCONFIG_TOOL, TICLANG_ARMCOMPILER) sourced from
SDK's imports.mak; user edits SIMPLELINK_SDK_LINUX in two .target
files and imports.mak once per machine
Vendors/TI/README.md:
- Complete setup guide covering network architecture (Linux Host
container + wfantund container two-container model), build
configuration, TPD pre-provisioning, border router setup,
flashing, IPv6 routing, and end-to-end verification
build.sh / sample/Makefile / Makefile:
- sample/Makefile clean: invoke ti_simplelink_wisun.target clean to
remove board .obj, .hex, .out, and SysConfig-generated files
- Board makefile clean uses *.obj glob instead of $(OBJECTS) to
catch stale artifacts from previous full-source builds

Extend the TI SimpleLink Wi-SUN example with clock synchronisation,
over-the-air firmware upgrade support
Changes:
- application/sntp_sync.c, sntp_sync.h: new SNTP client (RFC 4330)
that queries the IPv6 NTP server (default fd00::1) immediately after
Wi-SUN join; falls back to CSMP_BUILD_EPOCH if the server is
unreachable, keeping FND OTA schedule timers accurate
- application/application.c: replace fixed CSMP_APPROX_EPOCH seed with
sntp_sync() call; patch default_run_slot_image with TI-specific
hwid/filename/version before sample_data_init() writes NV on first
boot; add ti_ota_check_pending_activation() after osal_kernel_start()
- all board makefiles: add application_sntp_sync.obj to object lists;
- all board csmp_example.syscfg: increase FreeRTOS heapSize from
0x8000 to 0xC000 and timerStackSize from 0x800 to 0x1000 to
accommodate the additional SNTP and OTA stack usage
- all board SecureBoot.mak: fix SDK env var (SCCM_ → SIMPLELINK_);
embed build-date version stamp via $(shell date +%Y%m%d)
- Makefile: default ti_simplelink_wisun target to CONFIG=SECUREBOOT
so the signed MCUBoot binary is always produced alongside the hex
- tools/tpd_config_cc13xx.json: new TPD header config used by
add_tpdheader.py to wrap the signed .bin before FND upload;
hwid="CC13XX" must match hw_info in the FND cc13xx device meta file
- Vendors/TI/README.md: add Part C FND device type provisioning steps
(addGenericEndpoints.sh, cc13xxMeta.json, CSV import); add Step B.2
IANA PEN change (CISCO → TI); add Step F.5 Linux host mesh route;
add Step F.10 ntpd server setup; add Part H OTA firmware update
walkthrough (Steps H.1–H.13 covering build, flash, wrap, upload,
and verify)

Drop the manual CsmpAgentLib_sample.c version-string step from the OTA upgrade guide - FND reads the version from the signed image header, so the source edit was redundant and error-prone. Renumber the OTA checklist steps (H.3-H.13 → H.3-H.12) and correct the flash artifact reference from ns_node_csmp.hex to ns_node_csmp.bin. Replace the hardcoded SecureBoot.mak imgtool version (2.0.0) with 1.0.0+<YYYYMMDD> so each build carries a unique build number without requiring a manual version bump between OTA cycles. Remove the stale ti_ota_check_pending_activation() call from application.c that is now handled elsewhere in the startup sequence.
