nuwriter_scripts

Some scripts can help you program firmware into storages in this folder.

Requirement

Python3 for Window

After installing Python3, some plug-in as below must be installed.

pip3 install pyusb usb crypto ecdsa crcmod tqdm pycryptodome

Notice:

Tested python3 version is 3.10.1.
Please remember to add Python to PATH environment variable.

Libusb for Window

On Windows platform, it is required to install libusb manually.

Step 1: Download the library extract the download file.
Step 2: Copy MS64\dll\libusb-1.0.dll to C:\Windows\System32.
Step 3: Copy MS64\dll\libusb-1.0.lib to C:\Users\<user name>\AppData\Local\Programs\Python\<python ver>\Lib.

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_ddr2_128mb_download_and_run.bat or nuwriter_ddr3_512mb_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.

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
