I am using MK22FX512AVLQ12 controller in one of my product. I have made the development board for the same. But after assembly I am not able to programm the controller. i am using PE MICRO FX debugger. Before going for the development board design I first evaluated FREEDOM K22F evaluation board.
I used MCU Xpresso for the evaluation and PE MICRO (Rev B, D, FX Rev D) All these wer able to programme. Also i used LPC11U68 Eval board Debugger for programming . I was able to programm and debug using all these debuger.
But now when i made the development board of MK22FX512AVLQ12 controller and tried to programme then it is showing error.
I have attached the schematic and also made the modification in the hardware like pull up to EZ_CS pin as per the input from one of the forum.
I am facing this issue from last 3-4 days but still no sucess, please check the schematic and suggest the solution for the same.
