Hello,
My fellow colleague was messing around with the Stellaris and accidentally left the LM4F120 Launchpad in sleep mode. The current draw is that of 9mA which is the average we were getting when it was entering sleep mode. We've been reading of solutions regarding the LM Flash Programmer and the Unlock Sequence, but apparently this doesn't work with the LM4F120. We get the Cannot find target device, and it constantly freezes in the Assert and Hold Reset button, respectively.
When pressing the Reset button current draw drops to 4.5mA which is weird, we've also tried programming the launchpad with code composer while holding down reset but we keep getting frequency out of range.
Is there any other way that we can attempt to unlock it?
Thanks,
