MSP432E411Y:Program writing using MSP-BSL cannot recognize the response signal from MSP432

MSP432E411Y: Program writing using MSP-BSL cannot recognize the response signal from the microcomputer

Part Number: MSP432E411Y
Other Parts Discussed in Thread: MSP-EXP432E401Y,

Hi,

Continuation of the post below.

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1178530/msp432e411y-program-writing-using-msp-bsl-cannot-recognize-the-response-signal-from-msp432

After programming boot_uart_flash_MSP-EXP432E401Y.txt using a ROM-based bootloader, I get the following error:

I saw the waveform when BSL-Scripter.exe was executed on the command prompt above, but some data is sent from the microcomputer to BSL Rocket like BSL Rocket → MSP432 (yellow), then MSP432 → BSL Rocket (green) seems to be returning.

I am currently using the MSP432E411Y, so do I need a program for the E411Y? The C:\ti\BSL-Scripter\ScriptExampleWindows\E4xx_uart folder had only E401Y. If I need the txt file for MSP432E411Y, can you tell me how to generate it?

Thanks,

Eevee

    As far as bootloader is concerned, there is no difference between E401Y and E411Y. The protocol for UART bootloading is the same. The example will work for both part numbers.  

      To continue the discussion, can you please tell me a few things:

      - Do you have the device erased? Please show the content of the flash. There are various way to do this. The simple way is to look at the memory browser for the flash in CCS. Is it showing all 0xF? The only possibility for the error you are seeing is that the flash is not erased. Please refer to this post. https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/777432/msp432e401y-can-t-get-msp-to-program-over-serial

      - Do you have a LaunchPad? Is it possible for you to acquire a LaunchPad? You can find the LaunchPad at https://www.ti.com/tool/MSP-EXP432E401Y. 

      - Can you try the LaunchPad and the stock BSL example?  Please make sure R5 and R6 are populated with a zero-ohm resistor.

      - How many custom boards do you have? Do you have the same problem on all of your boards or only one?

      - Are you able to load the flash bootloader using JTAG and then run script_2.txt and script_3.txt. The flash bootloader project is in C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\nortos\MSP_EXP432E401Y\boot_loader\boot_serial_uart_flash. 

    As I demonstrated on the other post, I was able to run BSL without a problem.
