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
