MSP430F5514: Invoking UART BSL

Takayuki Miyazaki
Genius 10120 points
Part Number: MSP430F5514
Other Parts Discussed in Thread: UNIFLASH, MSP-FLASHER, MSP430F5529, MSP-FET, MSP-EXP430F5529LP

Hello Experts,

Our customer is using MSP430F5514 in current system, in addition, customer also has a plan use MSP430F5514 in the next model.

In next model, this application plans to invoke UART BSL. According to MSP430F5514’s datasheet, there is the description that is “A UART BSL is also available that can be programmed by the user into the BSL memory by replacing the preprogrammed, factory supplied, USB BSL”. Therefore, Our customer tried to update BSL memory. The UART BSL which customer had used is as follows. Also, customer seems to use Uniflash with the following procedure. After that, Customer tried to transfer BSL command to P1.2(UART Rx), however, customer was not able to confirm any response from P1.1(UART Tx ) of MSP430F5514.

Therefore, we got some inquiries about MSP430F5514’s UART BSL function.

  1. Regarding MSP430F5514’s UART BSL firmware, would customer be able to use the following firmware (MSP430F552x_550x_Family\UART BSL\ BSL.00.07.05.04.txt) ?    If this one is not supporting MSP430F5514, could you share UART BSL firmware with us, please ?

            This firmware may be for MSP430F552x_550x_Family. so, I tried to find it, but, I was not able to reach UART BSL firmware for MSP430F5514.

        2. Customer seems to use Uniflash with the following procedure.Can we have your Expert’s advice/comments on this please?

[ UART Firmware for MSP430F5514]

http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSPBSL_CustomBSL430/latest/index_FDS.html

MSP430BSL_1_01_00_01\Released_BSL_Images\MSP430F552x_550x_Family\UART BSL\ BSL.00.07.05.04.txt

[ Procedure ]

  1. Filled “0xFF” data into empty area of “BSL.00.07.05.04.txt file” and renamed “BSL.00.07.05.04_forUniFlash.txt”
  2. Convert textual data to binary data (BSL.00.07.05.04_forUniFlash.txt -> BSL.00.07.05.04_forUniFlash.bin)
  3. Burn-in “BSL.00.07.05.04_forUniFlash.bin” to 0x1000-0x17FF area by UniFlash(v4.5.0) tool.

 

It is really appreciated if you would be able to share your advice/comments on this.

Thanks and best regards,

Miyazaki

    Hi Takayuki

    After the procedure you mentioned before with the UniFlash, dose the BSL works well with the hardware invoke?

    Hi Gary,

    Thanks for your help.

    I could confirm that customer was evaluating MSP430F5514’s UART BSL with MSP430 LaunchPad. Since customer would like to support UART BSL, customer did not check if Default BSL (USB BSL) was working well.

    Customer tried to update BSL which was “MSP430BSL_1_01_00_01\Released_BSL_Images\MSP430F552x_550x_Family\UART BSL\ BSL.00.07.05.04.txt” as I mentioned. However, there was not any response from MSP430F5514’s UART.

    Therefore, I suppose, this UART BSL is not supporting MSP430F5514, Or ,UART BSL firmware was updated incorrectly with Uniflash.

    First of all,

    I’d like to clarify if this UART BSL is supporting MSP430F5514 or not. Because this file name is MSP430F552x_550x_Family. Can we have your comments on this, please?

    Regards,  Miyazaki

    Hi Takayuki

    The MSP430F5514 BSL should support UART. And due to MSP430F5514 and MSP430F552x are the same family so the UART BSL firmware should be work with MSP430F5514. So you can let the customer to do some tests below to find the bugs

    1. Before send the BSL command you should do invoke the device to BSL mode. For the invoke ways you can refer to BSL user's guide section 1.3 

    2.After you invoke the the BSL you should send the BSL password first. 

    3.If the customer finished the invoke and password and it even not work, you can capture the wave of Reset pin, Test pin , UART RX and TX pins singnals for me to analyze.

    Best regard

    Hi Gary,

    Thanks for your clarification and advice. I suppose this issue may be related to #2 BSL password. Therefore, to avoid miss, I tried to look for Host-sides-example-code in http://www.ti.com/tool/mspbsl, but, I could not find it.Could you share it with us, please? Or , if you will be able to share helpful wiki-URL, it is really appreciated.

    And then, there is possibility that UART-BSL firmware is updated incorrectly by uniflash, so, I’d like to suggest customer to update UART-BSL firmware by MSP-Flasher. What would you think this suggestion. Can I have your comments, please?

    You already noticed, customer would like to update the firmware via UART from External MCU.

     

    Best regards,

    Hi Takayuki

    For the external MCU host demo code for BSL we have the demo based MSP430P401 www.ti.com/.../getliterature.tsp
    You can have a try.

    I'll take over Takayuki Miyazaki and continue asking questions.
    This problem has not been solved yet.
    We confirmed that described in this thread, but we can not observe response from BSL(UART).

    Report my situation.
    . I'm writing BSL.00.07.05.04.txt to MSP430F5514 and trying to update using BSL(UART).
    . Writing BSL.00.07.05.04.txt to MSP430F5514, verify is also successful.


    . wave_00.JPG : Attach the BSL entry sequence waveform.

    . wave_01.JPG : There is no response to that command that don't require password.(change baudrate)

    . wave_02.JPG : There is no response to that command "RX password to unlock BSL".
    In the first place, wave_01.JPG and wave_02.JPG have no response to synchronization character. (1byte:0x80)

    . We confirmed command protocol.
    config_00.JPG : config value of logic analyzer when acquiring wave_01.JPG and wave_02.JPG


    Separately,
    although it is said that BSL.00.07.05.04.txt can also be used for MSP430F5514,
    there is no description of MSP430F5514 on the target device of BSL.00.07.05.04.txt in the following URL.
    about I am concerned that I can not use it.
    www.ti.com/.../slau319w.pdf
    -> 5.5 F5xx and F6xx Flash-Based BSL Versions


    Please tell me if there are other actions to check.

    Best regards.

    I have a question about this. For a part with UART BSL built in, the response to the hardware invoke sequence on /Reset and Test is hard-coded somewhere. But if a part comes with native USB BSL, is that same hard-coded response to the sequence even present in such a part? My understanding is that hardware invocation of UBS BSL is done completely differently. So perhaps there is never a response to the /Reset-Test sequence for such a part even if a new UART BSL is installed. If so, that would mean that any UART BSL would have to be invoked from firmware. That could explain why there is no response to the hardware sequence in this case. It would be interesting to see if invoking the UART BSL from firmware works.

    Hi Takayuki

    I have test the code today and it works well. When use the uniflash to down load the image you should set the Uniflash like this

    When you finished it will appear success like this

    When I finished the image download I use the BSL rocket (You can also use the MSP-FET) to do the mass erase with the UART BSL and it is success(I have attached the .txt file that be used by the BSL script

    Thank you for the test.
    We did the same test using MSP-EXP430F5529LP, and we were able to observe the response of the BSL-command.
    but, in case using MSP430F5514, we were not able to observe the response from BSL.

    Please answer three questions.
    .Can you test BSL.00.07.05.04.txt with MSP430F5514 ?
    .Is BSL.00.07.05.04.txt really compatible with MSP430F5514 ?
    .Is there a way to F/W update using the UART ? Other than using BSL.00.07.05.04.txt.

    Best regards

    Hi Takayuki

    Sorry for the late reply. We have not found the root cause yet. But for the work around here you can use the boot loader for flash device to support the UART. For more information you can refer to the document www.ti.com/.../slaa600d.pdf
    For the BSL, I will update it if I have any progress here.

    Best regards
