AM335x RTOS USB bulk endpoint example

Other Parts Discussed in Thread: AM3358

Are there any sample TI_RTOS applications showing how to implement a USB device with control, bulk in, and bulk out endpoints on the Sitara AM3358 processor?

The RTOS team has been notified. They will respond here.

The Processor SDK http://software-dl.ti.com/processor-sdk-rtos/esd/AM335X/latest/index_FDS.html has USB mass storage example for this, it is under ti\pdk_am335x_1_0_2\packages\ti\drv\usb.

Hi,

MUSB can support up to 126 devices, with bulk or control transfers. It is discussed here: e2e.ti.com/.../432404

MUSB allows the dynamic allocation of endpoints, to maximize the number of devices supported.

Is there an example to implement the endpoint dynamic allocation?

Best regards,

Daisuke

Hi,

Is there any other information to support up to 126 devices with the dynamic allocation of endpoints?

Best regards,

Dasisuke,

Can you explain your usage case of dynamic allocation? In Linux USB driver, the EP allocation code is in function musb_schedule() in drivers/musb/musb_host.c, but please note that this is only the function which allocates EPs, how dynamic allocation works also relies on the whole driver design, how the driver uses the EPs.

For the RTOS driver, I am checking internally but probably the answer is no.

Dasisuke,

We don't have dynamic allocation in USB RTOS driver.
