OMAP-L138 - USB2 stack

PaulSchoenke

Other Parts Discussed in Thread: OMAP-L138

The C6748 or the DSP side of L-138 doesn’t seem to have whole lot of packages in CCS4.2. The one that I especially need is for the on-chip USB2.0 controller. Can you comment as to the availability of USB2 stack? Or some example codes for the USB2 port, to initialize, to enumerate, to handle various interrupts generated by the USB2 module? We intend to use the USB2 port as just a Device, not OTG, run under SYS/BIOS.

Thanks again!

There are USB examples provided in the BIOUSB package, http://software-dl.ti.com/dsps/dsps_public_sw/psp/BIOSUSB/index.html.

Hi Christina,

Feedback from the software engineer on the project is that the USB support in the BIOS/USB package is extremely limited, and the source code to the library is not available for us to easily add the features that we need.

These threads on the TI E2E Community show people asking for a more general solution:

From my knowledge, licensing of the USB stack with Jungo does not permit TI to release the source code. It also does not allow support for custom class. I tried searching to see if there is a OMAP-L138 USB example available for download, but have not found one yet.
