Hello,

Im trying to program a custom board having TM4C1294NCPDT using EK-TM4C1294XL.

Now I have removed resistors R6,R7,R8,R10,R11,R15,R16 and R40 and connected JTAG pins and reset pin to controller board from Eval board. Also supply is given from Eval board.

The custom board runs ROM bootloader when connected with evaluation board also VDDC output is 1.2 V.

Reset is also working fine I get 2.8V when button is not pressed and 0 when pressed.

When i try to program the custom board is not getting programmed. I also unlocked the board using unlock from LM flash programmer.

Following are the LMFlash programmer screenshots.

What am i doing wrong? Please help.

Thanks.
