MSP430F5514: Communication through UART with a micro-controller having default USB BSL

Part Number: MSP430F5514
Other Parts Discussed in Thread: MSP430F5524, UNIFLASH

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. There is a folder having MSP430F552x_550x_Family. Could this be the right one? I don't want to lock the JTAG yet again. I still have to figure out how that happened. Any ideas on the same?

Please find attached the BSL files I used - BSL_00.08.88.39.txt (USB BSL) and BSL.00.08.08.04(UART BSL)

  • Hi Abhishek

    We have some problems about UART BSL with MSP430F5514. We are trying to fix this issue now. If I have any update I can update it to you.

    For more detail you can refer to https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/778508#pi320995=2

    Best regards

    Gary

  • Hi Gary,

    Please update me as and when you figure out the issue.

    Should I be able to use UART BSL with MSP430F5524? We are planning to use that in the next version. If I follow the same approach as mentioned in my post, will it work fine? I don't want my JTAG to be locked again. Any idea on why that happened?

  • Hi Abhishek

    Do you have the device MSP430F5524 device? I don't have this device now. If you have you can test it by the operation that I have mentioned in that thread

    https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/778508#pi320995=2

    Best regards

    Gary

  • Hi Gary,

    I don't have the device with me currently. I might get it soon. I will test and let you know. 

    Any idea why the JTAG of my MSP430F5514 got locked when I tried flashing the other UART BSL? Ideally, it should have just resulted in non-functioning rather than locking the JTAG.

  • Hi Abhishek

    The JTAG security lock key resides at the end of the bootloader (BSL) memory at addresses 17FCh through 17FFh. Anything other than 0h or FFFFFFFFh programmed to these addresses locks the JTAG interface.

    Best regards

    Gary


  • Hi Gary,

    In my case the contents from 17FCh through 17FFh was FFFFFFFFh. I had wanted the user application firmware also to be programmed. Hence I had combined the ti-txt file generated by building the project in CCS with BSL.00.07.05.04.txt. It looked like this:

    This procedure has worked okay with MSP430F5514 when I had used the USB BSL(BSL.00.08.08.04.txt). Could you confirm that I could do the same for MSP430F5524 with BSL.00.07.05.04.txt? Is there any other reason why my JTAG could have been locked?

    Thanks and Regards

  • Hi Abhishek

    If your hardware is good, the only way to locked the MSP430F5xx/F6xx devices is the JTAG Signatures bytes located at 0x17FC–0x17FF. For more you can refer to this documents http://www.ti.com/lit/an/slaa685/slaa685.pdf

    For check with your hardware, do you have capture the signals on JTAG pins (TEST RST TDI TDO TMS TCK) by a logic analyzer to me. I can check it for you.

  • Hi Gary

    Apologies for the late reply.

    (i) UART BSL BSL.00.07.05.04 has only 1916 bytes. BSL of MSP430 is 2048 bytes. The customer in the link has spoken of filling empty area with 0xFF. Is this to make up for the lesser number of bytes in the UART BSL? Is it necessary to do it? If I don't could it lead to locking of JTAG as it happened earlier? The USB BSL is of the full 2048 bytes.

    (ii) 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

  • Hi Abhishek

    #i I don't think it is necessary to make up the residual bytes. Could you help me to check what's the VCC voltage? Because we have the limitation to write the flash with no less 2.2V power supply. Could you share me more about the hardware setup with me? Like pictures of the board and the schematic or the connection pins between the debugger and your board

    #ii sorry I am not understand what you mean. The BSL pins include REST and test for BSL trigger, TX RX for UART communication.

    Best regards

  • Hi Gary,

    I did the following things:

    (i) I tried filling the residual bytes and flashing the BSL using UniFlash. I got the following error - "MSP430: File Loader: Verification failed: Values at address 0x01000 do not match Please verify target memory and memory map." I thought I would reflash the existing USB BSL that had come with the device. On doing so, the MCU again got locked out of JTAG access. The BSL file is exactly 2048 bytes long and has FF FF FF FF at locations 0x17FC - 0x17FF. This is the second time I am accidentally locking the MCU. Could you please explain why this is happening? Please find the BSL I was trying to flash. My pin-out looks like the one in the attached image, with the RST_SBWTDIO also connected to 3.3V through a pull-up resistor. There has been no problem while programming the firmware through the JTAG interface.

    (ii)My second question has been resolved. The UART BSL doesn't use the on-board UART pins but different specialised pins.

    We are using a Vcc of 3.3V. I am using a standard MSP430 programmer like the one in the image. Pl

  • Hi Gary,

    Apologies for the very long delay in replying. I have been busy with other things and have not had the chance to look into UART BSL. The only possible difference I can see with what I did and what you have mentioned is selecting the "Erase main and information memory" option. Could it be that not selecting it skips over writing into information memory and instead overwrites 0x17FC-0x17FF with other values thus inadvertently locking MSP430.

    Cheers

    Abhishek
