30### [USB Driver for Window](https://github.com/OpenNuvoton/MA35D1_NuWriter/blob/master/driver/WinUSB4NuVCOM.exe?raw=true)
31
32NuWriter must install **WinUSB4NuVCOM.exe** on the computer.
33
34## **Double-click Scripts for Windows**
35
36If your NuWriter_MA35 python running is ready, you can do following batch script files for Window directly.
37
38### **nuwriter_ddr2_128mb_download_and_run.bat** or **nuwriter_ddr3_512mb_download_and_run.bat**
39
40Download rtthread.bin binary file into DDR. The address is 0x80400000.
41
42### **nuwriter_sd_programming.bat**
43
44Program header, DDR timing setting and rtthread.bin binary file into SD card or EMMC.

64
65### **Use NuWriter_MA35.exe**
66
67Due to the python execution file size and saving network bandwidth, we just only release the python code in this repository. We also provide [NuWriter_MA35.exe](https://github.com/OpenNuvoton/MA35D1_NuWriter/blob/master/EXE/NuWriter_MA35.exe?raw=true) python execution. You can run the packaged app without installing a Python interpreter or any modules. You can use **NuWriter_MA35.exe** and do some modification.
68
69```bash
70To modify "py -3 nuwriter.py" to "NuWriter_MA35.exe"
71```
72
73For example, the **nuwriter_ddr_download_and_run.bat** modification is as following:
74
75```bash
76:forever_develop
77NuWriter_MA35.exe -a ddrimg\enc_ddr3_winbond_256mb.bin
78IF %ERRORLEVEL% EQU 0 (
79   NuWriter_MA35.exe -o execute -w ddr 0x80400000 ..\rtthread.bin
80)
81pause
82goto :forever_develop
