MSP432E401Y: how to use the rom bootloader of the device MSP432E401Y

Part Number: MSP432E401Y

The, SLAU746A,  User's guide MSP432E4 SimpleLink Microcontrollers Bootloader (BSL) describes how to generate a bootloader image to be stored in the flash. This bootloader is
used to upload the application image to the flash.

Questions: The device has a ROM, which contains a ROM  bootloader. I guess we can use this ROM bootloader  instead of compiling one and stored it in the flash.
Using the ROM bootloader, besides saving the flash space, avoid the software engineer from duplicate the process to generate the bootloader image.
However, I could not find any
document describes the ROM bootloader capabilities, how to use it, and what kinds of booting it supports (Ethernet, SPI, Uart, etc.).

Please point me to the documents, if they are existed. If there is none, I wondered why?

Thank you

Long

  • The ROM bootloader interfaces are found in the introduction of SLAU764A.  

    You can also find additional information in the technical reference manual,  .

    I think it would be best to use the BOOTCFG register and invoke a reset to start the ROM BSL.
