HI,

When plugging in the TWRK65F180M board, the MCU does not turn on. Only when I press the reset button does the D3 LCD start flashing. My computer then recognizes it as a device, pulls out the cperacceirosca vi olo ma po 10 seconds until the computer no longer recognizes it as a device The LCD of the D3 keeps flashing even though the MCU is not recognized by the computer.

To fix this, try these steps:

- Press and hold the RESET button (SW1).

- Connect the mini-USB port (J7) to power the board which should be numbered as a BOOTLOADER volume.

- Drag and drop the attached J-Link binary.

-Disconnect and connect the USB cable.

Then LEDs D3 and D5 light up but an MBED window opens and the MiniUSB port is not recognised. What can I do to fix the problem? Do I have to copy inside some specific file??
