TM4C1294NCPDT: Can we unlock with Uniflash v4？

Hi All,

Referring to the Uniflash Wiki below, it is stated that Tiva's Debug Port Unlock is available from v4.1.0.1250.

- UniFlash Latest Components

  processors.wiki.ti.com/.../UniFlash_Latest_Components

I am using Uniflash v4.2, but how do Unlock it? Is there a URL or Web page containing instructions?

I am using LMFlash Programmer and Stellaris ICDI to do Unlock, It is useful to be able to Unlock with UNIFlash and other Emulator (ex. XDS100v2-ARM, XDS110...).

Best Regards,

Takashi

    Takashi,

    I quickly opened a session on Uniflash for a ICDI interface, and the unlock option is there:

    The fact is that the unlock feature shows up for some interfaces, not for all (I also use XDS100v2, XDS110, XDS200).

    Gladly, the need for unlocking CPU's has been very low for our projects, so we don't even care to "remember exactly" which program works with each interface. But between Uniflash, LMFlash, and different probes, we eventually manage to unlock the stubborn MCU's when that is needed.

    Regards
