Now, I can launch some simple operation. for example, SYNC and READ_STATUS command and so on. But how to program a complete the content of S19 file to SH8? I launch WRITE_BYTE or WRITE_BYTE_WS command. but it seem don't be program to flash memories. Why? Please someone can give me some advices.

Hello,

you can´t write directly into FLASH memory. You havo to load your code to program the FLASH into RAM and execute it from there.

Hi Eckhard ,

In fact, I need to built a alone programmer without PC to burn source code in new target board. So I want launch some command and load source code to new mcu by BDM communication.  Is It practicable ? Please give me some advice again.
