USB Bulk transfer.

I have managed to get bulk transfer from host to STR711, but cannot get the other way working. I have set up EP2 as a bulk out in the usb_desc.c file and created a callback Callback_ep2. But the callback does not seem to get called. In fact I can't seem to get any USB interrupt that use EP2.

Do I need to set something else up first. For instance I have initialised a buffer for receiving the data with the following

SetEPRxAddr(ENDP2, ENDP2_RXADDR);

SetEPRxCount(ENDP2, 32);

SetEPRxValid(ENDP2);

but don't know if this is the correct thing to do.

Please help

P.

Could you also give us a version for IAR 4.30? There seems to be quite a lot of code to change and it would be easyer for you to do it... I'll try to do it myself, hope to make it work.

Hi.

Just one question, Risc.

Did you develop the ''RwBulk.exe''?

And if so, may i get the source code,

or better might you give me the programing interface for the Driver?

I am not able not find the documentation fo the driver on www.intel.com.

Thanks for your help.

Regards

Hi,

I am trying to get the Bulk example to work, I am able to get the readbulk working once, then no interrupts occurs.

The write functions seems to work, but I havn't been able to verify that the write actually takes place on the MCU.

Best regards,

Frank Andersen

Hi Iamanil

Sorry but I have not got any further with this problem, and I have also posted another request in this forum, but I get no answers.

It is still a problem for me to get read bulk to work correctly.

Best regards,

Frank Andersen
