USB High Speed on FRDM-K22F (KDS 1.0.0)

[mohamedessadoun]

Hi all,

I'm using FRDM-K22F board for a USB device application using KDS SDK.
I started from MSC sample to have bulk in/out.

All working fine except it is USB Full Speed.

I want to enable my device as HIGH_SPEED, I need to rebuild usbd_sdk_frdmk22f120m_mqx which needs EHCI as host controller interface.

The problem is, I cannot find the ehci interface source code anywhere in my KDSK while I have all concerning KHCI in "MQX_KSDK_1.0.0\usb\usb_core\device\sources\controller"

Am I missing something?

How to enable HIGH Speed config on K22F using KDS.

Thanks for your help.

Hi,

Was confusing between Kinetis platforms.

Anyway, having HS on this platform would have been great.

I will consider using K70.

Thanks for your time!

Regards.

Hi

The K22 has only FS USB.

For HS USB you will need something like a K70, plus external HW to interface its EHCI to the bus.

Yes, and so far, KSDK hasn't support EHCI yet, just MQX and USB stack ver 4.1.1 supports EHCI driver, and customer may use TWR-K70F120M and TWR-SER2 together to run the EHCI demos. Now our team is adding EHCI support in KSDK, and you will have it in the future.

Have a great day,
Kan
