Hello,

I would like to write to BSL area of MSP430F5525, but having problems like "Cannot write to target".

Is there any example available?

Thank you in advance,

Hi Gyro76,

The BSL memory is protected against unintended modification. It can only be unlooked inside the BSL code (see MSP430x5xxx Family Guide, SLAU208G, chapter 1.11.2).

Maybe you should consider the way Wiliam Goh implemented the MSP430 Field Updater. It uses the TI original boot loader to load a RAM based boot loader. Such a RAM based boot loader is much easier to implement and debug (http://focus.ti.com/docs/toolsw/folders/print/msp430usbdevpack.html)

Guenther
