AM5718: AM5718 sample code and reference materials

Hi Astro,

I don't think there is any reference code available for the above USB functions in the RTOS SDK.

The only reference example available for USB is the examples available at <PDK_Install_Path>\packages\ti\drv\usb\example and the diagnostic tests available at <PDK_Install_Path>\packages\ti\board\diag\usb*

There are reference code available for display on LCD. You can refer to the diag test at <PDK_Install_Path>\packages\ti\board\diag\lcd* but these might not have been validated.

Hi, Parth

Thank you for your reply. What about the following？

・ BB2D function (drawing rectangles and lines)

・ CAL function (MIPI CSI-2 camera input)

Thanks,

Astro

I am not sure about this, I'll check and get back on this.

Hi, Parth

Thank you for your reply. 

If you have any update about BB2D function, please let us know.

Hi Astro,

There is no reference code available for BB2D function.

Hi, Parth

I understood that the following sample code is not available.

Is it correct to understand that the following features are not supported as drivers? Or is the driver supported?

・ USB hub class, USB HID class, USB 3.0 OTG function, USB device CDC function

・ BB2D function (drawing rectangles and lines), Display function (display on LCD)

・ CAL function (MIPI CSI-2 camera input)　

In the URL below, there was a description "We don't support USB CDC with RTOS." However, the sample code seems to be provided.

Is it okay to understand that AM57xx is not supported?

<pdk> \ packages \ ti \ drv \ usb \ example \ usb_dev \ cdc_serial

Thanks,

Driver does seem to have support for this functions.

I'll need to check this one.

We do have reference example for CSI functions as mentioned in the previous post

I look forward to your reply.

Does the above refer to diagnostic tests?
If not only the diagnostic test but also the sample code, please let me know.

Thanks,

Q1. You say that it supports the USB function in TI-RTOS.  Is there any document that can be used as a reference? 

Q2. Is there a sample code for the USB function I want to achieve in Linux?

Parth Nagpal said:

BB2D function (drawing rectangles and lines), Display function (display on LCD)

These examples are not available as well.

Q3. I would like to know if I can somehow use the library from other supported devices (AM335x), including the means to divert it. Since TI-RTOS does not have a BB2D driver, is it possible to develop on a register basis?

Thanks,

Astro

Edited / added a comment !!

Hi, Parth

Do you have any update?

THanks,

We do not have any reference document on this.

This is something we need to check with the Linux team. I'll re-assign this thread to Linux team for answer of this query.

Yes, as long as the IP is same, you can port the driver easily from other supported devices.

AM335x and AM437x use the same IP as AM57xx, right? If you have any reference information about driver porting, please let me know.

We do not have any reference document on this.
