TI中文支持网hi ， 工程师们。
我在运行用ti15.4stack oad示例程序的时候，oad显示成功之后sensor程序却不能回连了。重启sensor也没有反应。
coprocessor 是使用ccs导入的 C:\TI\simplelink_cc13x2_26x2_sdk_3_20_00_68\examples\rtos\CC1312R1_LAUNCHXL\ti154stack\coprocessor工程，并下载的。
sensor 是使用的ccs导入的C:\TI\simplelink_cc13x2_26x2_sdk_3_20_00_68\examples\rtos\CC1312R1_LAUNCHXL\ti154stack\sensor_oad_offchip_secure工程下载的。
sensor升级文件是ccs build的C:\TI\simplelink_cc13x2_26x2_sdk_3_20_00_68\examples\rtos\CC1312R1_LAUNCHXL\ti154stack\sensor_oad_offchip_secure生成的bin文件。
collector是home目录下/ti/ti154stack_linux_x64_2_06_00_24/example/collector的host_collector。
Viki Shi：
你有抓包看过吗？

回复 Viki Shi:
没有，但是下载完成之后，传感器设备再次刷新bim.hex就可以重新启动了。

回复 Viki Shi:
但现在问题在于，每次都提示完oad completed successfully之后都需要再次刷新bim.hex。

是否按照官网 步骤：
The out of box example for the sensor_oad_offchip project uses the Linux Collector to update the FW on a sensor device. The following steps walk through the process of performing an OAD:Please note that prebuilt images are only provided for the 1352R1 device. If you are using a different device, please refer to section "Generating the Required Binary Images" in this document on how to build the images from the projects.
The Linux collector requires the coprocessor device to operate. To setup the coprocessor device: * Load <SDK_DIR>/examples/rtos/CC1352R1_LAUNCHXL/ti154stack/hexfiles/coprocessor_cc1352lp_tirtos_ccs.hex onto the device using Uniflash
For the sensor device: 1. Add the Off-Chip BIM image <SDK_DIR>/examples/rtos/CC1352R1_LAUNCHXL/easylink/hexfiles/offChipOad/cc13x2r1lp_bim_offchip.hex to the image list 2. Add the user application <SDK_DIR>/examples/rtos/CC1352R1_LAUNCHXL/ti154stack/hexfiles/sensor_oad_offchip_secure_cc1352lp_tirtos_ccs.bin to the image list 3. Load both images onto the device using Uniflash
