MSP430F5659: Flash Device Bootloader for UART on 5659 (which comes preprogrammed with USB BSL)

Dubs Mozz

Part Number: MSP430F5659

The msp430f5659 comes preprogrammed with a Boostrap Loader (BSL) for it's USB port.

The documentation says " a UART BSL is also available for devices with USB module that can be programmed by the user into the BSL memory by replacing the preprogrammed, factory supplied"

does anyone have any experience with this? Does TI have code that will do this?

We'd like to use the 5659, in fact we have it already in a design, but need to use a UART Bootloader, and we'd rather not change IC's( I see the 5359 has the UART BSL)

Any one with experience on this?

Thanks for your help,

Yes, you can replace factory default BSL with customized version. There are TI open source examples.

I'm not so much interested in creating a customized BSL, as I am in just replacing the preprogrammed BSL that uses the USB pins with the UART one that uses the UART port.

I was thinking there might be other people who do this, and maybe there's a script out there somewhere that already does this?

Thanks

Yes, this is inside TI open source BSL examples.

There is last USB / UART / I2C factory version for all devices with updatable (stored in flash) BSL. If you can't find binary (TI txt file), you just need to rebuild sources (for your device familly) with your device selected as target. And than replace (unlock / erase / write) factory BSL by SBW or JTAG.
