Hi Wu,

1. Which board are you using, Keil MDK or your own development board?

2. Which tool is used to erase/program the flash, TI NowFlash or TI CCS5.x, or tool from other company?

3. Which JTAG emulator is used in your test, TI XDS100V2 or SD XDS510 USB, or other?

Regards,

Thank you for your reply!

1. It is my own development board.

2. Keil uVision4.

3. JLink JTAG emulator.

Here is the result.

Hello Wu,

Is the JLink emulator able to connect to your board? Can you compile/execute a simple project in SRAM?

Hi Wang！

Yes，JLink emulator can connect to my board。It is strange that i cannot execute the flash erase command。

I donot know how to execute a project in SRAM .

Before， I down load the code to flash to run。

I canot confirm the project run in SRAM or not。

Where is the application note？
