My development board FRDM - K64F board was not functional properly, I thought the old board was faulty so I requested for a new board.
I connect my new board and I can see it in the Device Manager (COM 4), when I try to connect to Putty Emulator I get an error message, unable to open serial port.
I have updated Windows driver with mbedWinSerial_16466, done a bootloader update with 0244_k20dx_bootloader_update_0x8000.bin
I tried running 'hello world' and in the workspace no probes found. The only way to get my LED on is to have it in bootloader mode.
Now I don't want to return the board, how can I sort this problem.
Do I need to install any drivers or change any settings ?
