Hi All :-)

I have troubles unlocking the BSL on CC430F6137

first i do Mass erase:

// Host

80 01 00 15 64 A3

//response from the micro:

00 80 02 00 3B 00 60 C4 -0x00 Operation Successful

then I send the default password to unlock the BSL

//RX password to unlock BSL

//Host:

80 11 00 11 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF 4E C9

response from the micro

00 80 02 00 3B 05 C5 94

and get 0x05 - BSL Password Error.

An incorrect password was supplied to the BSL when attempting an unlock.

What am I doing wrong?

Is the default password different from all 0xFF?

Thank you in advance

Hi,

The CC430F6137 has a 32-byte (16-word) password, but that example from slau319 that you based your sequence off of shows just a 16-byte password (which is only used on MSP430F5438 non-A parts).

Try something like this instead:

80 21 00 11 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff 9e e6

I think this thread will help you: http://e2e.ti.com/support/microcontrollers/msp430/f/166/p/215430/760031.aspx#760031

There are also some sample code related to BSL:
