hi,
i have some questions about the ROM Bootloader of MSP432E401Y
1. if the FLASH is empty without any code inside, when power on boot, it will automatically jump to execute the ROM bootloader without any need of HW trigger, is it correct?
2. and how to modify the MAC address if using the ROM bootloader to do the FW upgrade?
3. how to erase the FLASH clean enough so that can let MSP432E4 jump to ROM Bootloader automatically once power on due the the FLASH is totally empty?

Yes!

The ROM Bootloader looks for the MAC address in Flash User Registers. These registers can be modified by using "Uniflash" as shown in the following screenshot.

Please refer this forum post on how to erase Flash.
