Part Number: MSP430F5438A

Hi team:

when i use the MCU in the for normal use. The MCU flash will lost some bootloader code. 0x6200 - 0x6400 is the bootloader program. The blank block is the lost part.

I want to know how to lose the content in mcuflash. Then I will do the corresponding test. For example, whether MCU has a specific power-up and power-off timing（by the way，i don‘t use the low power mode）

So how did this happen.

In my main code.

The bootloader program will only erase the code segment during the upgrade process.

Conditions for entering the upgrade process:Received the host upgrade command message (the message has CRC check).

Currently No boot loader CODE BUG was found to cause program corruption.So i think it's not a software problem.
