Other Parts Discussed in Thread: MSP430FR2676

Hi, I am currently trying to program the "MSP430FR2676" device using the "SBW" protocol. When I referenced the documents and programs downloaded from the official website, I encountered several issues:

In the "slau320aj.pdf" document, what is the relationship between "JTAG fuse", "JTAG password", and "JTAG lock"? Also, in the "Replicator430FR.c" file within "slau320aj.zip", at line 153, which of the three mentioned above is actually being checked?

pdf table 2-11

pdf table 2-11(2)

Please kindly provide answers to the above questions. Thank you.

    For Fuse check, it is for Flash device, and not for FRAM device.

    For all the FRAM device, they are use JTAG lock without password. Do you want to use password and use the SBW to unload it? If so, you can try to search for this function:

    Hi Eason,

    I mainly want to know which functionalities are applicable to this device. Some discrepancies between the code in the files and the documentation have confused me a bit.

    I will use "EraseFRAMViaBootCode_430Xv2()" for my attempts.

    Thank you for answering the above questions.
