 ## prebuilt demo applications and its tools
 
+### CAN bootloader demo
+
+[download CAN.Bootloader.Simulator.on.Win10.7z](https://github.com/autoas/ssas-public/releases/download/CanBL-0.0.1/CAN.Bootloader.Simulator.on.Win10.7z), use 7z to unzip it and just double click the run.bat to let the demo run.
+
+```bash
+# File list:
+App.s19.sign # prebuilt demo Application s19 file and it was signed
+FlashDriver.s19.sign # prebuild demo flash driver s19 file and it was signed
+CanBL.exe # prebuilt demo bootloader
+CanSimulator.exe # CAN bus simulator over IP socket
+
+Loader.exe # tool Loader act as UDS client to do software update, this tool can also be used to sign a s19 file.
+libwinpthread-1.dll # runtime dependency
+run.bat # entry point, double click to run the demo
+```
+
+After run, a tmp folder will be generated to store the related logs
+
+```bash
+Flash.img # Application Flash simulation
+Fls.img   # NvM/Fee Flash simulation
+can0.log  # CAN message over the simulated CAN bus 0
+loader0.log # loader UDS message log
+ssas.log # also a copy of loader UDS message log
+```
+
+```
