MSP430F5514: Connections for using UART-BSL using BSL Scripter Tool

Abhishek Veeraraghavan

Part Number: MSP430F5514
Other Parts Discussed in Thread: UNIFLASH

I want to use UART to interact with the BSL to update the firmware. The suggested pin-connection is this.

I am not using the launchpad. From what I understand the connection to the TEST and RESET pins is to invoke the BSL. I can, however, use the software option to invoke the BSL by using the line - ((void (*)())0x1000)();

In this case, can I just use a USB-UART converter(FTDI232)/FET with just the Rx, Tx and GND connections as in normal UART communication?

    Hello Abhishek,

    I believe that should work.

    Hi Dennis, I had composed a long reply with two files attached and then the TI website did its magic of vanishing all my text.

    I was trying to communicate with the BSL through UART. The BSL wasn't responding with the right ACK. The MSP430 had come with a default USB BSL(the second file 5706.BSL 00.08.88.39.txt attached above). I figured that it might need replacing with an UART BSL. I chose the UART BSL from the MSP430F552x family(the first file attached above), combined it with the hex code of the application into a single .txt file and flashed it using UniFlash. I checked the contents of the locations 0x17FC-0x17FF - where the password resides - and it was 0xFF FF FF FF(it should be either that or all 0s). On flashing, there was an error message, something along the lines of incorrect number of bytes. It turns out that it ended up locking the JTAG access to my MCU. Unlocking it is only possible through the BSL which is what I was trying to accomplish in the first place, so I'm in a bit of a soup. I have a few questions.

    (i) Is it possible to communicate to a device having USB BSL through UART? Is replacing the USB-BSL with the UART-BSL the right thing to do?

    (ii) If so, where do I get the right UART-BSL file from? I can't find one for my device family?

    Hi Abhishek,

    Please check out this thread which discusses using BSL via UART vs USB.

    Hi Chris

    Thanks for your reply! I will go through the link, try my hand at using UART BSL and let you know the results.

    Cheers

    Hi Abhishek, 

    Were you able to resolve your issue?

    Hi Chris,

    Apologies for the late reply. I haven't been able to look into the matter. I will do so and let you know.

    Cheers

    Hi Dennis, 

    I realised that the MCU has BSL transmit output and input pins which are separate from the UART Rx, Tx pins. Should I make connections to the BSL pins and not the on-board UART module?

    Thanks and Regards

    Abhishek

    Hi Abhishek,

    Yes.  See the pinout table (below) for UART-BSL from the datasheet.
