DM6446 USB bulk communication as Device(client).

Hi,

I am working DM6446 USB bulk communication as client mode in high speed.

It uploads datas to windows XP on Host PC by bulk transfer.

But I can not find example source code.

Most examples of Davinci are related as Host function.

How does it can be started?

 

Thank you.

    If I understand correctly, your WinXP PC is your USB Host and DM6446 is your USB slave, correct?  If so, you would normally get a hotplug event on your PC USB Host controller which you can use to launch a program to start the trasnfers... if DM6446 is indeed the slave, I do not beleive it can start the trasnfer by itself, it relies on host to start it.

    You can use GadgetFS to write you own application on the DM6446 end or use MSC class gadget *g_file_storeage" and simulate yourself as a Mass storge device and exchange data with PC.
