Other Parts Discussed in Thread: MSP-GANG, MSP-FET,
Hi experts,
When my customer was writing a program with MSP-GANG to a custom board using MSP 430FR6877, some boards became unwritable.
When they tried to connect using CCS, it said "The Debug Interface to the device has been secured".
We are trying to recover with BSL for the solution.

Q: Could you tell me the possible causes?
Since there is not much information, it may be difficult to answer, but it would be helpful if you could make some assumptions.
Note:
・The 0xFF80 to 0xFF84 area has not been rewritten by the implemented software.
・In Setup- > SecureDevice in the MSP-GANG Programmer, SecureDevice is not checked.
・Occurred in 2 of 24
・No cross check with a known good board.
Best Regards,
O.H
