How to erase flash memory after a mistake ?

Hi,

I have made a board with a MSP430F1222. Everything was going right but while doing some modifycation of the software, le MSP430F1222 stopped to respond to BSL request and to J-Tag.

I think I have find out why : I have enable WDTNMI on the WDTCTL register so now the RST/NMI is not used for the reset... And it is enable right at the start.

Is there a way to erase the flash memory in this condition ?

There is always the possibility to replace the MSP430F1222 by a new one but I will have to send it back to my subcontractor, and I want to save some time.

Thanks.
