MSP430F5529: The Debug Interface to the device has been secured

Hi Yue,

This error could be caused by a few things most common is either attempts to write to JTAG protected memory or a set JTAG protection fuse. A quick check for the first is to see if they can program one of our example projects using their current setup.

For the second, they will need to unlock the JTAG fuse by erasing the JTAG/SBW signature values as described in the MSP Code Protection Features document (SLAA685)

Hi Yue,

Are you working from a launchpad?

So by default the MSP430F5529 comes loaded with USB BSL. The simplest way to do this in my opinion would be to download the python firmware upgrader (part of our USB Developers Pack), and you can just add:

@0182
03 00
@17FC
00 00 00 00

To the end of your ti-txt file. I have done this for the 5529_LED_Blink example included in the python firmware upgrader tool. 

You can put your MSP430F5529 in BSL mode (if you are using the launchpad), by pressing the BSL and reset switches at the same time, and then releasing reset first. The Python_Firmware_UpgraderGUI should be able to find and program the device over USB once it is in BSL mode. 

Best Regards,
Brandon Fisher
