Tool/software:

hi,

When am debugging it was showing"CORTEX_M4_0: Can't Run Target CPU: (Error -1268 @ 0x1090001) 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 9.9.0.00040)"

how to resolve this

    Hi,

    The error says the address 0x1090001 which is out of bound.  You need to check your code if you are accessing a memory location that is beyond the available memory which is only 1MB on TM4C129. Since you are getting a hard fault, also check if you are accessing a peripheral that is not yet enabled. Accessing a peripheral that is not yet enabled will cause a hard fault.
