Hi all,
                  am working on openSDA of  TRK KEA128 development board. I wanted to make my own openSDA  board  so  that I  could  flash  my  MCU  which  is used  in  my  project, I  referred  the schematics  of TRK KEA 128  and  designed a board with same  components being used as of TRK KEA 128. I am finding few difficulties while  flashing.

1.         First of  all  when I  connect  it  via USB  to my  computer  it  doesn’t detect  ( using Code warrior to flash and debug).

2.         Flashing happens once I do with development board (by connecting UART_TX, UART_RX, SWD_DIO,  SWD_CLK   and  RESET )  but  not from  my  board (                           by connecting  UART_TX, UART_RX , SWD_DIO, SWD_CLK and RESET).
3.         Observation done from my board is that LED doesn't glowing once I connect USB.

Does openSDA controller IC needs to be flashed ??
