Hello, everyone,

Hi,

I am using the drivers supplied by Cypress for the FX3, and have modifed the inf file with my VID, PID, and descriptor strings. It works well, but of course it is no longer certifed and I get the Windows warnings. I want to submit my drivers for WHQL, but I am told that since I have modified a driver that was previously certified, there is an easier process to follow. Is there an app note or some other guidance that tells me how to get my new file certified?

Thanks,

Sid

Hi, I’m writing to the forum since I’m really confused about the association Thread-Socket for the GPIF sync FIFO interface. I used the Slave sync FIFO example (putting DMA channels on AUTO) as a starting point but I’m now unable to go ahead.

My needs are:

1)       EP1 working as IN and  OUT, transferring and reading data to and from the PPort using automatic DMA.

2)       I then need a second endpoint EP2 working too  as IN and OUT

EP1 is typically used to transfer big chunk of data and is accessed using async  data transfer (from the CyAPI point of view; not async GIPIF!) . This works perfectly and I’m able to send and receive data to/from the GPIF interface.

In this case your selection was:

#define CY_FX_EP_PRODUCER               0x01    /* EP 1 OUT */

#define CY_FX_EP_CONSUMER               0x81    /* EP 1 IN */

#define CY_FX_PRODUCER_USB_SOCKET    CY_U3P_UIB_SOCKET_PROD_1    /* USB Socket 1 is producer */

#define CY_FX_CONSUMER_USB_SOCKET    CY_U3P_UIB_SOCKET_CONS_1    /* USB Socket 1 is consumer */

#define CY_FX_PRODUCER_PPORT_SOCKET    CY_U3P_PIB_SOCKET_0    /* P-port Socket 0 is producer */

#define CY_FX_CONSUMER_PPORT_SOCKET    CY_U3P_PIB_SOCKET_3    /* P-port Socket 3 is consumer */

In your reference design you the set up the 2 DMA channels using :

…

    dmaCfg.prodSckId = CY_FX_PRODUCER_USB_SOCKET;

    dmaCfg.consSckId = CY_FX_CONSUMER_PPORT_SOCKET;

…

    apiRetStatus = CyU3PDmaChannelCreate (&glChHandleSlFifoUtoP, CY_U3P_DMA_TYPE_ AUTO, &dmaCfg);

..

For the USB 2 FX3 channel and

…

    dmaCfg.prodSckId = CY_FX_PRODUCER_PPORT_SOCKET;

    dmaCfg.consSckId = CY_FX_CONSUMER_USB_SOCKET;

…

   apiRetStatus = CyU3PDmaChannelCreate (&glChHandleSlFifoPtoU, CY_U3P_DMA_TYPE_ AUTO, &dmaCfg);

For the FX3 2 USB  DMA channel.

First question: how maps the USB socket number to the Endpoint number. Looking at your example I should use CY_U3P_UIB_SOCKET_PROD_1    and CY_U3P_UIB_SOCKET_CONS_1    for EP 1 and  CY_U3P_UIB_SOCKET_PROD_2    and CY_U3P_UIB_SOCKET_CONS_2 for EP2,…  is this correct ?

In order to set up a second    group of DMA channels I modified the above definition as following

#define CY_FX_EP_PRODUCER               0x01    /* EP 1 OUT */

#define CY_FX_EP_CONSUMER               0x81    /* EP 1 IN */

#define CY_FX_EP_PRODUCER_NEW      0x02    /* EP 2 OUT */

#define CY_FX_EP_CONSUMER_NEW     0x82    /* EP 1 IN */

#define CY_FX_PRODUCER_USB_SOCKET    CY_U3P_UIB_SOCKET_PROD_1    /* USB Socket 1 is producer */

#define CY_FX_CONSUMER_USB_SOCKET    CY_U3P_UIB_SOCKET_CONS_1    /* USB Socket 1 is consumer */

#define CY_FX_PRODUCER_USB_SOCKET_NEW    CY_U3P_UIB_SOCKET_PROD_2    /* USB Socket 2 is producer */

#define CY_FX_CONSUMER_USB_SOCKET_NEW   CY_U3P_UIB_SOCKET_CONS_2    /* USB Socket 2 is consumer */

#define CY_FX_PRODUCER_PPORT_SOCKET    CY_U3P_PIB_SOCKET_0    /* P-port Socket 0 is producer */

#define CY_FX_CONSUMER_PPORT_SOCKET    CY_U3P_PIB_SOCKET_3    /* P-port Socket 3 is consumer */

#define CY_FX_PRODUCER_PPORT_SOCKET_NEW    CY_U3P_PIB_SOCKET_1    /* P-port Socket 1 is producer */

#define CY_FX_CONSUMER_PPORT_SOCKET_NEW    CY_U3P_PIB_SOCKET_2    /* P-port Socket 2 is consumer */

I then copied your code to set up the 2 new DMA channels:

…

    dmaCfg.prodSckId = CY_FX_PRODUCER_USB_SOCKET_NEW;

    dmaCfg.consSckId = CY_FX_CONSUMER_PPORT_SOCKET_NEW;

…

    apiRetStatus = CyU3PDmaChannelCreate (&glChHandleSlFifoUtoP_new, CY_U3P_DMA_TYPE_ AUTO, &dmaCfg_new);

..

For the USB 2 FX3 channel and

…

    dmaCfg.prodSckId = CY_FX_PRODUCER_PPORT_SOCKET_NEW;

    dmaCfg.consSckId = CY_FX_CONSUMER_USB_SOCKET_NEW;

…

   apiRetStatus = CyU3PDmaChannelCreate (&glChHandleSlFifoPtoU_new, CY_U3P_DMA_TYPE_M AUTO, &dmaCfg_new);

First question: is my socket mapping correct according to the description of what I need ?

If yes, EP1 works perfectly both IN and OUT, but EP2 simply doesn’t.  In none of the directions…

Do I’m missing something?  Any suggestion ?

Thanks in advance, Joel

P.S. I’m using a 2 bit addr 32 bit data sync GPIF slave fifo model (GPIF designer)

Hi all

I got a new laptop with USB 3.0 port. I can use USB 2.0 to download code. The max speed is 38.1MBS.

But I cannot switch to USB 3.0 port on same laptop. USB3.0 can download firmware. But it does not recognize my firmware. Even I download firmware by USB 2.0-only  port then switch to USB 3.0 port nothing will happen.

Laptop is Lenovo X230. OS is windows 7 professional(x64) . USB driver is DVK 1.1.1.

I think the problem is come from firmware. Does it different between USB 2.0 and USB 3.0?

Thanks

I have self-powered USB device running on FX2. Everything works except reconnection after USB cable is plugged out. When I plug-in the cable, device is not recognized on the host side and I have to power it down and up again to get it working.

I have implemented VBUS monitoring so device controls DISCONNECT bit. Except for that, what else should be done on the device side when "disconnected" and "connected" conditions are detected? 

Help, anyone?

Hello,

does anyone has tested the SPI Boot option with the FX3 successfully ?

best regards

What is the correct procedure to do a Device Remote Wakeup from SS, HS, FS?  I see flags in the API document telling me if they are enabled.  However, I would like to wakeup the host when I get certain interrupts on the device side.  The closest thing I can find is  CyU3PUsbSetLinkPowerState

The chip is 68013A.

We transfer data at speed 54MBps, I have tested the top speed of my board is about 32MBps. What I used is: EP6/AUTOIN/512*4 buffer/BULK mode. Do you have any methord to meet my data transfer speed need?  Thanks for help.

Hello,

     How to get  flag of "CYU3P_GPIF_OP_THR0_READY" in code?

Hello,

    When I am using Cypress USB Control Center , sometimes a message box populated saying "Please correct the fireware descriptor table". This messagebox appears before the main window appears. What's the matter?

    Best, Regards.
