C5515 UsbStick - connecting to a PC host via USB

Hi,

Your steps look correct.

Yes, it's working with me. I'm using XP. We are under processing to release new CSL release and USB testing program (for PC application) will be included.

Regards,

Hyun

Ok, thanks for the verification that I'm doing the right thing.  I believe then that I may have defective hardware; I'll get another USBstick and try it out again. 

I was wondering, in the next release of the USB testing program (PC app), would TI also be making the source code available?  This would really help with integrating the functionality into other applications.  When (approximately) would the new CSL release be available?

Regards,

Ed.

Hi Ed,

From what I know the CSL v2.01 USB examples are not meant to support eZdsp55x5, they are for EVM55x5 circuitry.

What happens is that the board does not enumerate in the USB bus in any of the CSL USB examples.

Also I do not know anyone that has used out of the box witout modifications the CSL in order to exercise any of the USB examples in eZdsp55x5.

Since it works for Hyun I'm also keen to see how he managed the 2.01 examples to work on eZdsp!

What does work though is SpectrumDigital's USB example from here

-> http://support.spectrumdigital.com/boards/usbstk5515_v2/reva/files/usbstk5515_BSL_RevA.zip

so you can test if your hardware is ok using the usb example from there (USB mouse buttons).

Hi Ed,

The new CSL release will happen within a couple of months. It's under testing with C5515EVM and C5515 eZDSP.

Regards,

Hyun

Good news to all.

We'll include a source code of PC application.

Regards,

Hyun

Hi Christos,

While it's not possible with the C5505 UsbStick (EVM was the only option), the C5515 USBStick can apparently communicate with the host via USB.  There was some discussion about this on another thread, if I understood it correctly:

  http://e2e.ti.com/support/dsp/tms320c5000_power-efficient_dsps/f/110/t/47278.aspx

Plus Hyun's posts back this notion.  But when I get a new stick and actually get it working myself I'll let everyone know.

Regards, Ed.

That is really good news.  Keep up the good work everyone!

Regards, Ed

Ed,

I have a eZdsp5515 and my remarks are for the CSL 2.01 on eZdsp5515.

Hyun could enlighten us  on what CSL version he tests eZdsp5515 and works ok on USB.

Regards,

Christos

Hi,

I want to clarify of which CSL version working on eZdsp USB SD card example.

    CSL 2.01 CSL 2.1 (under testing and future release)

C5515 eZdsp          USB_SD card (X) USB_SD care (O)

C5515 EVM         USB_SD care (O) USB_SD care (O)

The reason CSL 2,01 dose not work with USB_SD card is that the hardware different between EVM and eZdsp. The next CSL 2.1 release will fix it.

Other USB example not using SD card work with both EVM and eZdsp.

Regards,

Hyun

All,

The PC application (source) code  attached. This code will be added to CSL formal release. You can start use this code.

Regards,

Hyun

This is really great!  It looks to have absolutely everything that anyone would need to get going on both sides - target and PC host.  I just have to wait until I my new USBStick arrives as the one I have is still not functioning properly.  But I'll keep everyone posted as to my progress with the new hardware.

Thanks again for your efforts and responsiveness.

Regards, Ed

hyun, I am having some trouble running the c5505usb_ep_diag.exe. Specifically it is

waiting to attach to the target USB port. Let me give you some details.

I am using a C5515EVM and have been able to test the user USB (not JTAG) port using the

USB mouse example that comes with the C5515 installation CD.

I am trying to write a program that sends and receives packets of data between the host

pc and the EVM5515 user USB port which is what your example does that you posted on

wiki.

I read the instructions in the README1st below:

///////////////////////////////////////////////////
How to Run the c5505usb_ep_diag.exe

This test is designed for testing the read/write for C5505 USB <--> PC. The USB FIFO

size is 512 byte.


1. Install the C5505USB_EP driver on the Host PC (WinXP)

1.0.    open a DOS command window and type in the following commands
1.1.    wdreg -inf <directory path to .inf>\C5505USB_EP_driver.inf install
1.2.    wdreg -inf <directory path to .inf>\C5505USB_EP_device.inf preinstall
1.3.    copy "wdapi1010.dll" to %windir%\system32

Normally the %windir%\system32 directory is C:\WINDOWS\system32
if you want to make sure the directory location, you can do following under window
Start (on the bottom-left corner of the PC) -> Run -> %windir%\system32

2. Power up the C5505 EVM and connect a JTAG to the EVM

3. Load and run the "UCSL_USB_PollExample_Out.pjt" (usb/example1), 

"CSL_USB_IntcExample_Out.pjt" (usb/example2),
or CSL_USB_DmaExample_Out.pjt" (usb/example3) under c55xx_csl\ccs_v3.3_examples or

c55xx_csl\ccs_v4.0_examples
in CSL release

4. Connect the USB cable between C5505 EVM and the PC, Window will prompt "a new drive

has been found";
Do not use wizard, just tell the installation program you have a specific location, then

tell it where
the "C5505USB_EP_device.inf" is. Wait until it finishes.

5. USB Endpoint Read Test: Run c5505usb_ep_diag.exe by double click it. Simply select

5.1.    Select "4" for the first prompt (Read/Write from pipes)
5.2.    Select "4" for the second prompt (Check Streaming READ speed)
5.3.    Type in "81" for the third prompt (Use EP1 IN)

6. USB Endpoint Write Test: Run c5505usb_ep_diag.exe by double click it. Simply select

6.1.    Select "4" for the first prompt (Read/Write from pipes)
6.2.    Select "5" for the second prompt (Check Streaming WRITE speed)
6.3.    Type in "02" for the third prompt (Use EP2 OUT)

7. The reading and writing speed will be displayed after the tests are finished.

The source code for the c5505usb_ep_diag.exe is in C5505USB_EP_diag_src. You will need

the Microsoft
Visual Studio 2005 or later to be able to build it.
////////////////////////////////////////////////////////////////////////////////////////


However after I load and run the target program (UCSL_USB_PollExample_Out) and then run

the host program (c5505usb_ep_diag.exe) the console message is:

'dos> Please make sure the device is attached:'

Also STEP 4 above did not happen. The PC did not recognize the USB port and I don't see

"unknown devices" in my device manager.

Can you please walk me through what I need to do....I would appreciate it. Now the

original USB (mouse) program is also not working.

Hi,

I guess that you are using CSL 2.01. We know there are enumeration issue on that release. There is a USB descriptor not correctly implemented. We have fixed it and will release soon.

Regards,

Hyun

Hi Hyun, have you got good news for the developers that use USB and CSL 2.01? There is a prevision of the new release of C5505_USB_Host_Tool or CSL?

Regards,

Andrea

I'm trying to use the c5505usb_ep_diag tool to aid in developing on our target custom hardware.  I followed the instructions in the readme1st file, and had no problems.  The device manager shows a Jungo device, with a C5505USB_EP (driver jungo 12/14/2009) and WinDriver device (driver Jungo 8/31/2010) under it, all of them indicate they are operating properly.  When I try to do step 5:

             5. USB Endpoint Read Test: Run c5505usb_ep_diag.exe by double click it. Simply select

I get a command window that says:

             Please make sure the device is attached:

And cannot issue any test commands.  The csl_usb_dma_example code has run to its background loop with no errors displayed.  Am I missing something?

Thanks in advance for your help,

Dan
