MSP432P401R: BSL Scripter failing initialization with MSP-EXP432P401R dev board

The first thing I would suggest is to have a look at this post, which talks about the same error message. You haven't included source code, so not sure how closely this may match your situation.

Hi Bob,

I have downloaded "MSP432BSL_1_01_00_00" and flashed my MSP-EXP432P401R dev board with the firmware image "BSL432_MSP432P401.txt" using UNIFLASH.

I ran the example "script_P4xx_uart.txt" again afterwards. I am still getting the same error.

Is this something you can try to reproduce on your end?

Also, I am not sure what you meant when you mentioned that I haven't included source code. What source code are you expecting?

Thanks,

Jeffrey

Hi Jeffrey,

could you check that the COM PORT is correct? MSP-EXP432P401R dev board has two ports, one is the debug port, and the other is the Application UART. The Application UART port shall be chosen.

Other than that, the bootloader will go to sleep mode after 10 seconds. before starting the BSL Scripter, press the reset button on the debug board part.

Let me know the result of these two check, and if they are not still working, I'll think another possibility. Thank you!

I have been using the Application UART. I have tried it again today. I pressed the RESET button on the dev board just before running the BSL-Scripter. I am getting an ACK_ERROR_MESSAGE. Attached is the log file.

Thanks,

Jeffrey

Hi Jeffrey,

on the last post, the log file attachment shows the 543x family script example. Could you please retry with the ScriptExampleWindows\P4xx_uart\script_P4xx_uart.txt ?

The first command shall be: MODE P4xx UART 9600 PARITY COM134

Hi Jeffrey,

Glad to hear that is working now! :)

I don't expect the Bootloader is erased when it is executed. The bootloader sector in @20:2000h only erased by the JTAG/SWD when you run the debug mode in CCS for example and having the configuration in Debug setup to "Allow erase BSL area".

One other note: when you already download an application using the bootloader and program the interrupt vector area @0h-100h, you can not talk to the bootloader anymore. Maybe this is the reason why you download the Bootloader image again using debugger, because at the same time you are erasing the @0h-100h and the bootloader become available again. You can validate this by keeping @0h-100h empty, and download the image, and then reset the device. bootloader should work in this case.

However, the bootloader is still callable when you call it via software, or activate the hardware invocation. Hardware invocation of the bootloader is part of the security features in MSP432P4. you configure a pin to locate the invocation with certain polarity. when the device is powered up, the bootcode will read the polarity on the configured pin. if it is the configured polarity, the boocode will execute the bootloader.
