CCS/TM4C1294NCPDT: not able to dump the code because its permanently goes into hibernation

Hi Bob Crosby,

Already I have try to unlock the part by using LM Flash Programmer and I am not getting any error while unlocking. But before unlocking I am trying to update to ICDI Firmware but its showing "failed to program ICDI Device". Is it mandatory to update the Firmware before unlocking. Kindly go through the below screenshot.

Thanks & Regards ,

Anamika.

Hi Bob Crosby,

You can go through below steps what I did

1)Configuration  ---> Quick set (TM4C1294XL Launch Pad)

2)In Program menu and flash utilities ,we didn't do any changes.

3)In other utilities  ---> selected MAC address mode and selected Fury, Dust Devil, TM4C123 and TM4C129 classes.

4)Finally I clicked on UNLOCK button after that

- confirm with yes

- on next MsgBox hold reset, connect

- click ok, while still holding reset

- release reset

- power cycle board (and restart Flash tool?)

Thanks & Regards ,

No, it is not necessary to update the ICDI firmware. You should not have gotten that error message. I question whether your ICDI is still properly working. If you open your Windows Device Manager with the EK-TM4C1294XL launchpad connecting the Debug micro USB port of the launchpad  to a USB port on the PC, does it look like the "Stellaris ICDI JTAG/SWD Interface" is installed correctly?

Hi Bob Crosby,

Yes, there is no any wrong with Stellaris ICDI interface, it showing as like below....

But I don't know why the flash is not erasing with LM Flash Programmer...I need urgent help sir...Will you please give me any suggestion...

Thanks & Regards,

Hi  Bob Crosby,

Sir I have tried below mentioned code for hibernation once you try the below code and then after try to erase the flash. Let me know the status...
