I have downloaded the USB device code provided by freescale developers to my Cortex M4 K60 board where i have not used any external pullups and MAX3353EEUE IC for the circuit,
i made few changes in the code, those are
1. Disabled weak pull downs ==> USB0_USBCTRL &= ~0x40;(Because DP line was detecting its Voltage up to +1.2V only) in USB.C
2. sellected Clock source as FLL insted of PLL in USB.H
3.defined NO_PLL_INIT = 1 in sysinit.C
my problems are
1.after running the program its contineously displays "Enter USB Reset handler"
please help me to solve this problem....
Thank you so much
