When I attempted to flash the program to the device (for the TIDA-00951 DC-DC converter), I received the error messages seen in the screenshots below. The operation timed out while attempting to erase sector A and now all read 0x0000. The power supply is has also dropped from 5V to about 3.9V since first connecting to the target.
I have another device to replace the locked one with, but I want to avoid making the same mistake. Is there anything specific I may be doing wrong or steps I can take to make the accidental lock less likely to occur?
