USB Driver for Window
NuWriter must install WinUSB4NuVCOM.exe on the computer.
Double-click Scripts for Windows
If your NuWriter_MA35 python running is ready, you can do following batch script files for Window directly.
nuwriter_ddr_download_and_run.bat
Download rtthread.bin binary file into DDR. The address is 0x80400000.
nuwriter_sd_programming.bat
Program header, DDR timing setting and rtthread.bin binary file into SD card or EMMC.
nuwriter_spinand_programming.bat
Program header, DDR timing setting and rtthread.bin binary file into SPI NAND flash.
nuwriter_nand_programming.bat
Program header, DDR timing setting and rtthread.bin binary file into NAND flash.
Bash Scripts for Linux
If your NuWriter_MA35 python running is ready, you can do following bash script files for Linux directly. If not, the install_linux.sh will help user to install related python module installation.
# ./install_linux.sh
nuwriter_ddr_download_and_run.sh
Download rtthread.bin binary file into DDR. The address is 0x80400000.
nuwriter_sd_programming.sh
Program header, DDR timing setting and rtthread.bin binary file into SD card or EMMC.
nuwriter_spinand_programming.sh

Troubleshoot
Fail to create symbolic folder
Create symbolic folder conv failed
- To switch Developer Mode in Window. To enter [Settings], [Update & Security], [For developers], [Developer Mode] page, then set it On
- Use Administrator permission to install python3, libusb and utilities.
Use NuWriter_MA35.exe
Due 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 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.
To modify "py -3 nuwriter.py" to "NuWriter_MA35.exe"
For example, the nuwriter_ddr_download_and_run.bat modification is as following:
:forever_develop
NuWriter_MA35.exe -a ddrimg\enc_ddr3_winbond_256mb.bin
IF %ERRORLEVEL% EQU 0 (
NuWriter_MA35.exe -o execute -w ddr 0x80400000 ..\rtthread.bin
)
pause
goto :forever_develop
