MSP430FR6877 BSL JTAG

Other Parts Discussed in Thread: MSP430FR6877, MSP-GANG

Hi Champs,

My customer is designing water meter using MSP430FR6877. MSP-GANG is used to program the MCU. They have tried JTAG and BSL downloading. The content of 0xFF90 was different comparing 2 downloading methods. When using BSL, the content of 0xFF90 is 0xFFFF, while using JTAG, the content is 0x5555. This address is reserved by interrupt vectors. I checked the datasheet, and didn't find any information.

Customer wants to know where the difference comes from? Is there any potential risks?

Thanks a lot.

BR,

Young
