Hello,

I want to request a detailed from scratch installation instruction for Linux! Readme file in the SDK is not working in Ubuntu 16!!!

I saw many people had this problem! also mention how to change *.elf to *.img

Thanks,

I have an application with two boards,  one of them use a CY7C68013, let's call this board A. one of them has a CY7C65630 and CY7C68013 let's call this board B,

the problem is that when I plug the A board to a PC, then everything is OK. but if I pug the A board to B board CY7C65630 downstream port, then CY7C65630 upstream port plug to PC. then the PC couldn't detect the USB device type. 

why this hub will cause this failure? how to fix this problem( workaround)?

Thanks,

David Sun

Board A plug-in PC USB power, properties are.

Hardware Ids:  

USB\VID_0547&PID_5253&REV_0000

USB\VID_0547&PID_5253

Configuration Id

Board A plug-in Board B, then Board B plug-in PC. properties are

This is the property of the hub chip. Optovue RTVue Base Controller is the CY7C68013 on board B. unknown USB device is the board A plugged in the hub port.

the hub driver is 6/21/2006, version is 10.0.17763.1. hardware ID is

Hello community!

I'm new here and have no prior experience with Cypress products. We are working on a solution to stream mpeg2-ts from a file over usb to an ASIC (proprietary stream manipulation which we have no control on)  and then back over usb to another file.

MPEG_TS (Linux PC) --> USB --> 8bit parallel into ASIC --> 8bit parallel out from ASIC --> USB --> MPEG_TS

This is probably trivial for someone with experience with FX2LP or similar. For me however there are a lot of unknowns and a not so smooth learning curve. I'm looking for advice to get started faster, and to avoid usual pitfalls. I found that most of the AppNotes are geared towards getting the stream into the PC. I could not find any that explicitly talk about putting it out to parallel. All help is welcome!

regards

Hello,

I asked before and I got USB-Serial driver from:

https://community.cypress.com/message/201696?sr=search&searchId=0fc37be6-8197-42bb-a4f3-b48d979b1bb0&searchIndex=4#201696

Even though I got an answer,

it could not be installed so far due to other development elements.

sorry..

This is a reconfirmation.

Driver displayed at the top of this 'Microsoft update catalog' will be used.

◇　Microsoft Update Catalog

link: https://www.catalog.update.microsoft.com/Search.aspx?q=Cypress%20-%20USB%20-%2011%2F12%2F2018%20

It is only  one driver ' cyusb3.sys', can it be used for both x86 and x64?

Hello!

I have a cypress microcontroller CY7C68013 EZ-USB FX2(not a fx-2LP). Can i  use last version of CyApi.lib to download the firmware hex file into the CY7C68013 RAM? (C# or C++ vesrion).

And do I understand correctly - Eclipse IDE for C/C++ Developers can be used to develop firmware for CY7C68013 EZ-USB FX2 ?

Hello:

     I am currently using a fx2 based usb camera devlopment board, When I use Cyapi.lib to design a QT program  to communicate with it, Things all going fine to me, I can get a picture rate about 7fps with this camera board.But when comes to linux Ubuntu with libusb, I can't get a single full picture with the camera board, I put my linux code and  the picture I captured to the attachment files.

     So what's the diffrence between this two mechanism, IS the Cyapi.lib open source?If so, where can I download this code?And I read the cyusb_linux_1.0.5 code which is offered in the fx3 1.3.4 SDK version, I see there is no diffrence between the company code  and my code, at least the libusb usage is the same.Also to state more clearly, I paste the windows code which I use at the bottom:

int i;
CCyControlEndPoint * ctrlPoint = Camera -> ControlEndPt;
ctrlPoint -> Target = TGT_DEVICE;
ctrlPoint -> ReqType = REQ_VENDOR;
ctrlPoint -> Direction = DIR_TO_DEVICE;
ctrlPoint -> ReqCode = 0xa8;
ctrlPoint -> Value = 0;
ctrlPoint -> Index = 0;
PUCHAR ctrlBuf = new UCHAR;
PUCHAR buf = (PUCHAR)image;
LONG length = 0;
//ctrlPoint -> XferData(ctrlBuf, length);
CCyBulkEndPoint * BulkIn = NULL;
int eptCount = Camera -> EndPointCount();
for (int i = 1; i < eptCount;  i++)
{ 
bool bIn = Camera -> EndPoints -> bIn; 
bool bBulk =  (Camera -> EndPoints -> Attributes == 2); 
if (bBulk  && bIn) BulkIn = (CCyBulkEndPoint *) Camera -> EndPoints; 
   } 
int packageNum = 5;
BulkIn ->SetXferSize(size / packageNum);
  LONG packageSize = size /packageNum;
if (size % packageSize) packageNum ++;
OVERLAPPED inOvLap[8];
UCHAR * inContext[8];
LONG recieveNum[8];
int totalNum= size;
for (i = 0; i <packageNum; i++) inOvLap.hEvent = CreateEvent(NULL, false, false, NULL);
for (i = 0; i < packageNum; i++) 
{
inContext = BulkIn -> BeginDataXfer(buf, packageSize, &inOvLap);
buf += packageSize;
}
ctrlPoint -> XferData(ctrlBuf, length);//this vendor cmd tell the camera board to start send frame data
for (i = 0; i < packageNum; i++) 
{
if(!BulkIn -> WaitForXfer(&inOvLap, 1000)) 
{ 
BulkIn->Abort();
            WaitForSingleObject(inOvLap.hEvent,INFINITE);
};
}
buf = (PUCHAR)image;
for (i = 0; i < packageNum; i++)
{
BulkIn -> FinishDataXfer(buf, (LONG &) recieveNum, &inOvLap, inContext);
totalNum -= recieveNum;
CloseHandle(inOvLap.hEvent);
buf += packageSize;
}
ctrlPoint -> ReqCode = 0xa9;
ctrlPoint -> XferData(ctrlBuf, length);//this vendor cmd tell the camera board to stop send frame data

I have a composite device with two CDC devices exposed as USB Serial Ports.  When this device is reset the COM port numbers often change.   I want then to stay the same.

The driver used is: Cypress\Cypress USB-Serial Driver\DriverBinary\CDC_Driver\bin\win10\x64\CypressSerial.inf.  I have seen in other posts that for certain Cypress serial devices there is a "Enable Port Persist" option in the advanced settings for the COM port.  I don't see the same thing for my CDC devices. 

How to "Enable Port Persist"?

Hi,

I want to take advantage of USB 3 power that is near 7W. But my design contain Fx2LP. So is it posssible to connect Fx2lp wit usb 3 receptacles? I am ok with speed limited to 480 Mbps as per USB2.0 specifications.

     Hi，chip is CY7C68013A，The configuration is shown in the figure.

     when the other USB ports plug and unplug the U disk, this  device’s EP6 endpoint will be deadlock，but other endpoints are functioning normally.Then just Reset Pipe EP6 on Control Center and the device will work normally.

    Can you tell me what’s wrong？ Thanks.

Hi,

Here are the requirements that I need to fulfill:

1. Use one port as UART;

2. Use another port as GPIOs, I need 6 GPIOs;

3. The UART and GPIOs function work at the same time.

Does CY2C65215 meet my requirements?

Thanks,

Wujun
