Source for libxud_u.a

[yhb]

Hello,

I need to know XUD library deeply for my project. So, I want to see the codes of that libraries and learn with it.
But, I couldn't find the codes for libxud_u.a library anywhere (not only Git hub, but also xtimecomposer).

Where can I get the source codes for libud_u.a library?
At least, I need a source of XUD_Manager function.

The source code of XUD isn't publicly available.

What would you like to know?

Blanco & Ross,

Thank you for your answers.
On my project, I need to implement functions for shutdown & restart the USB module, and switch the FS/HS mode dynamically in restarting process.

So, I want to dig into the XUD_manager.
Thanks,

Me too!
I even want to develop a USB host/OTG on XMOS processor.

So can we have the source code for XUD library, especially the fundamental operations on ULPI interface of the USB transceiver:
* Read/Write operations at bytes/words level.
* or even better: Read/Write operations at packets/transactions level

Thanks!

The easiest way to achieve this would be to restart the device (soft reboot) and emulate and un-plug event.

At boot you can they decided whether to run at HS or FS (XUD_Manager() takes a speed param) based on some non-volatile memory or user input.

You could even run separate images if the functionality of the different modes is very different.

Ross,

Thank you for your suggestion. I'll change our designs as like as you suggested.

But, the limitation of XUD_Manager is really impediment for designing USB products.
I'll issue a request to resolve it via our XMOS supplier.

Thanks,
