4.    The case of using full functions with external NOR Flash Memory and SDRAM

In this section, we shall describe the way to build, download and execute SH7264 M3A-HS64G50 solution available in the porting kit with NOR Flash Memory and SDRAM.

4.1                How to Build

1) Using Command-line prompt, change the directory to “Solutions\SH7264_M3A_HS64”    C:\MicroFrameworkPK_v4_1>cd solutions\SH7264_M3A_HS64

2) Run

    Msbuild dotnetmf.proj /t:build /p:flavor=debug;SERIALFLASH=false

      Flavor: <debug|release|rtm>       SERIALFLASH : <ture|false>

      If you want to debug your program using E10A-USB Emulator, please specify “debug” for “flavor” option.

      In this case, specify SERIALFLASH to “false”.


4.2                Board switch settings

There are two DIP switches located on the CPU board. The function of each switch and its connection are shown below:

1) SW5

  Set SW5 of the M3A-HS64G50 board as below to startup from NOR Flash.

Figure 4.1   SW5 settings

2) SW6

    Regarding to the SW6, set all switches should be OFF.




4.3                Download using E10A-USB

1) Setup the E10A-USB Emulator

     Install the E10A-USB Emulator software into your PC.

During install, you should select the device group for E10A-USB then specify “Super H RISC engine family SH-2A device group”


2) How to start downloading using E10A-USB

Extract the HEW workspace for SH7264 M3A-HS64G50 Porting Kit from file SH7264M3AHS64.zip at any place in your PC.    

In the following instructions, we will assume it is installed in “c:\workspace”

Start the Hew with choosing below menu

 iii) CPU and memory initialization

  In order to download data to flash properly, CPU and memory should be initialized as following.

-         CPU : Cache must be disabled.

-         Memory : Port controller must be initialized.


In order to initialize them, run the batch file as below,

·         Specify the batch file
