USB as HOST on K66

anand_s — Wed, 10 Apr 2019 13:23:39 GMT

Hi all,

We are trying to port K60 to K66 using codewarrior 10.6.4 and MQX 4.2. version. We are successfully ported and tested all the required peripherals except USB. We are using USB0 port as host. As we know there is no driver file available for K66 or K65 and also no support for codewarrior. In our application it only requires usb's old version(not need USBv2). So we used the driver files of K60 in K66, now the problem is we cant open the host device(Mass storage). We are stuck at that point. Please help me out. How can i successfully port USB driver of K60 to K66. What is the difference between K60 USB0 and K66 USB0.

Thanks and Regards,

Anand.S

Hi ANAND:

K66 support is available in MQX v5

www.nxp.com/mqxv5.

as far as I know, for usb full speed, the usb0 port is the same.

for usb high speed, k60 needs a crystal, k66 doesn't.

If USB host mode is used a crystal is still needed with the K66.
