MSP432E401Y: MSP432E401Y

Part Number: MSP432E401Y
Other Parts Discussed in Thread: UNIFLASH

I was trying todo UART Firmware update on MS432E401Y eval board using Boot code. In application I updated BOOTCFG and tried the scenario using LM flash programmer with GPIO pin. Though everything worked but when wanted to try again for some reason my eval board has stopped working. I have few queries related to same:

(1) Which tool to be used for UART firmware update for MSP432E401Y board , because I don't see this option in LM flash programmer list.

(2) Did Update using LM flash programmer on MSP432E board has any issue? Did it corrupt the micro? when I try to flash using CCS , it never comes out of writing to flash, the  RED led on board remains ON forever.

I did try to update using Uniflash programmer. though programming shows successful, the application is not running. Erase flash and read back from flash looks fine but still I don't see the board working..?

Please let me know if there is a way to get the board up..

    Uniflash is the right tool to use for MSP432E4 devices.

    I haven't tried this scenario but the MCU could have been locked. Please refer section 5.3.1 Unlock Sequence Using Uniflash and XDS Debug Probes in the following Application Note: 

    Note:

    • Please type in the command (instead of copying pasting) as there might be formatting issues.
    • Also the unlock command has to be performed twice. This is not documented in the Application Report.

    Once the MCU is unlocked, use Uniflash to program over JTAG or Bootloader.

    Thanks,

    Sai

    Hi Sai,

    Thanks for your input. 

    I am looking for COM/Serial port  tool to download firmware. Uniflash i understand doesn't support serial port option. For older chips LM flash programmer was used but for MSP i m not sure.

    Hello Arathi,

    To use the Bootloader on MSP432E4 you will need BSL Scripter. Please refer the following SimpleLink Academy for a detailed explanation on how to use the Bootloaders on MSP432E4 device.

    Thanks,
    Sai
