MCF52223 USB Slave, Fail to receive PC Tokens

Bartington — Thu, 14 Dec 2006 21:13:41 GMT

Hello

I'm working on using USB using the MCF52223 for one of my projects.

I've manage to detect Host and slave connection and disconnection.

When the PC is connected:

I Wait for a reset then when i get it

- i set EP0 in default state

- Send a reset for 10ms

- switch on the USB_EN_SOF_EN bit

- Get EP0 ready for reception (packet size 8 byte, OWN, DTS)

and expect to get an TOK_DNE interrupt

But it dowsn't happens....

Please Help

thanks loads

Olivier
