Other Parts Discussed in Thread: MSP430FR4133

Hi, we are developing a systems that use the MSP430FR4133, and are having issues with an error message about the security fuse being blown during debugging.

We are developing using Code Composer Studio v6.1.1, using the MSP430FR4133, and the MSP-FET430UIF JTAG debugger.We are trying to use timer in capture mode.When we are capturing events more than 3000 our code got stuck and program counter goes to 0x04.When I try to debug again it shows me Security fuse blown error.

    Amardeep,

    Below I have attached a link to a very similar E2E post that was resolved after trying multiple solutions. Please give these solutions a try, particularly the solution at the end that seems to have worked for everyone having the similar problem. Let me know how it goes!
