I am using Keil uVision, my device is tm4c123gh6pm.
Everything works fine unless it indicates that "Could not find an Cortex-M device in the JTAG chain!".
I checked the forum to solve it, it seems my trouble is worse than that.
That I don't have any attached devices at all!
I tried to install it and it seems that installation is ok but it just doesn't work!
From device manager, I didn't find the device either.
How may I bring it back to work please?
Thanks!
