TM4C123GH6PZ: Device is locked up in Hard Fault or in NMI.

Part Number: TM4C123GH6PZ

Hi,

I am getting a error,

Device is locked up in Hard Fault or in NMI. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 6.0.504.1)
CORTEX_M4_0: Flash Programmer: Error while writing to Flash memory
CORTEX_M4_0: File Loader: Verification failed: Values at address 0x00000000 do not match Please verify target memory and memory map.
CORTEX_M4_0: GEL: File: C:\Users\Admin\Desktop\C_32bit\C\Debug\C.out: a data verification error occurred, file load failed.

I have crossed checked Oscillator, JTAG connections and reset circuit.

I have even changed the device.

Regards,

Akshay

Hello Akshay,

To recover the device, have you tried Unlocking it via the LMFlash Programmer?

Hello Akshay,

I haven't heard back from you, so I’m assuming you were able to resolve your issue.

I will close this thread now, but if you have not solved this issue then post a reply below (or open a new thread if the thread has locked due to time-out).

Hi Ralph,

Sorry for replying late.

I tried giving reset connection to Pin 2 of JTAG.
This seemed to have solved my problem.
I will reverify.

Thanks and regards,
Akshay
