It's the first time using MC56F8006. When I use the USB TAP to connect the Codewarrior 8.3. It's appear a problem which is the "USB open failure", I think I don't have the driver. But I can't confirm that I don't have the USBTAP's driver or the MC56F8006's driver. Who can give me the USBTAP's driver and the MC56F8006's driver?
Thank you very much!
In general, the USBTAP driver is installed when you install CodeWarrior for DSP56800E ver8.3, you do not need install separate USB driver.
Hope it can help you.
do you use MC56F8006 demo board or your target board you designed yourself? If you use your designed PCB board, pls check the power supply, GND and check if JTAG connector signals pins are assigned as the that of the demo board.
