PROCESSOR-SDK-OMAPL138: USB bulk mode, pdk_omapl138_1_0_11

Part Number: PROCESSOR-SDK-OMAPL138
Other Parts Discussed in Thread: OMAP-L138

Hello,

I am working on adding USB support to one of my product developing, I was able to initialize the USB_0 in bulk mode with IN and OUT end point 2, and everything works fine.

Now I want to add one more OUT only endpoint, and I am unable to find the document explaining the steps to add new endpoint to interface.

I would really appreciate if anyone can provide the link to the document on it or steps to add the endpoint.

Thanks,

Kushal

Hello Kushal,

Are you doing this in Linux, or RTOS/baremetal?

Thanks,

HI Jianzhong Xu,

I am using TI-RTOS for this.

Hello Kushal,

Unfortunately we can no longer support TI-RTOS SW development for OMAP-L138. Please refer to this announcement and find resources there.

I was able to add the end point by adding new end point descriptor in the driver file usbdbulk.c and by updating the structure "uint8_t g_pBulkDescriptor[]" and "const uint8_t g_pBulkInterface[]".

Hope this helps if anyone is looking for same thing.

Thanks,

Kushal
