How can I erase the flash of MSP430F5309 without JTAG interface?

Other Parts Discussed in Thread: MSP430F5309


I have a question about erasing flash memory of MSP430F5309.

I know that it is possible to erase flash by using the JTAG Interface with Fet-Pro430 tool.

But now I can not use the JTAG Interface to target board.

I wrote the keyboard binary file to target board through 32bit shell boot mode.

But it was failed to wrote the binary file.

Then, I tried to write binary file but it was also failed.

Maybe, I think some flash memory of MSP430f5309 was lost.

How can I erase the flash of MSP430f5309 through 32bit shell boot mode without JTAG interface ?

Is there any command about erase?

Please help me out.

Thank you. :)
