UNIFLASH: V6.1 with Tiva board

Need to erase incorrect MAC address. Trying "Unlock" gives "Error! Module Closed". If I read the MAC address first then try to unlock, the error changes to something like "You already have a flash interface established."

There is a note in this section of Uniflash that says "Please press and hold the reset button while powering up before clicking unlock" but this does nothing.

Using a Tiva TM4C129ENCPDT board.

Hello Mark,

I've heard that the Unlock feature doesn't work well in CCS Uniflash in a few versions, so I would recommend if you just need to do that quickly for LaunchPad to use our LM Flash Programmer to do this: https://www.ti.com/tool/LMFLASHPROGRAMMER

If you need to do this over JTAG, then you need to use Uniflash's Command Line process which is documented in Section 5.3.2 of our JTAG User's Guide: https://www.ti.com/lit/pdf/spma075
