Is it supported win7 or win8 ?
The ATK Toolkit is not supported for Win 7, since the USB that ATK uses has been
developed by a third party called Jungo. Unfortunately Freescale does not have access
to the source code of this driver. You try working via UART.
The customer will have to switch to the Manufacturing Tool called MFG.
MFG Tool will be the main tool to flash / run images on a board. MFG Tool supports Win7.
