2. 2MB Flash (Matter only, enable BT DFU, LZMA compressed, SW - 1 and 2)#
IMPORTANT: LZMA compression is REQUIRED for 2MB flash with OTA.
Kconfig: boards/tl5218x_retention_ota_lzma.conf (explicitly specified)
CONFIG_CHIP_OTA_REQUESTOR=y
CONFIG_CHIP_DFU_OVER_BT_SMP=y, CONFIG_CHIP_DFU_OVER_BT_SMP_BUILD=y,
CONFIG_LZMA=y, CONFIG_COMPRESS_LZMA=y
CONFIG_DUAL_MODE=0

Output:
build_tl5218x_retention_lzma_v1/zephyr/merged.bin -> flash this
build_tl5218x_retention_lzma_v2/zephyr/merged_dfu.lzma.bin -> DFU over BLE SMP
build_tl5218x_retention_lzma_v2/zephyr/matter.ota -> OTA upgrade
3. 2MB Flash (Matter + Zigbee dual mode, LZMA compressed, enable BT DFU)#
Prerequisite: copy Zigbee firmware
cp <zigbee_fw>.bin ${ZEPHYR_BASE}/TL323X_FW/ZB/Zigbee-SampleDemo.bin
e.g.
cp ${ZEPHYR_BASE}/TL323X_FW/ZB/sampleSwitch_tl323x_log.bin ${ZEPHYR_BASE}/TL323X_FW/ZB/Zigbee-SampleDemo.bin
Note: This dual-mode configuration is for 2MB flash only. LZMA compression is required due to limited partition space.
Kconfig: boards/tl5218x_retention_dual_mode_ota_lzma.conf (explicitly specified)
CONFIG_CHIP_OTA_REQUESTOR=y
CONFIG_CHIP_DFU_OVER_BT_SMP=y, CONFIG_CHIP_DFU_OVER_BT_SMP_BUILD=y,
CONFIG_LZMA=y, CONFIG_COMPRESS_LZMA=y
CONFIG_DUAL_MODE=1 (action switch mode)
DTS Overlay: src/platform/telink/tl5218x_2m_flash_lzma.overlay (default)
Build:

Output:
build_tl5218x_retention_dual_mode/zephyr/merged.bin -> flash this (sboot+mcuboot+matter+zb)
build_tl5218x_retention_dual_mode/zephyr/merged_dfu.lzma.bin -> DFU over BLE SMP
build_tl5218x_retention_dual_mode/zephyr/matter.ota -> OTA upgrade
4. WARNING: 2MB Flash with OTA but NO LZMA (NOT RECOMMENDED)#
This configuration will show a warning during build and may fail at link time.
Kconfig: boards/tl5218x_retention_ota.conf (explicitly specified)
CONFIG_CHIP_OTA_REQUESTOR=y
CONFIG_CHIP_DFU_OVER_BT_SMP=y, CONFIG_CHIP_DFU_OVER_BT_SMP_BUILD=y,
CONFIG_LZMA=n, CONFIG_COMPRESS_LZMA=n
CONFIG_DUAL_MODE=0
WARNING: Building this configuration will show a warning:
“tl5218x with 2MB flash and OTA requires LZMA compression. Please use a config with ‘lzma’ suffix and set CONFIG_COMPRESS_LZMA=y. Continuing compilation anyway…”
Note: Build may fail at link time if firmware size exceeds 924KB (0xe7000) partition limit.
Solution: Use the LZMA-enabled configuration (target #2) instead.
