Is it possible to have a DR_DATA action drive data onto the GPIF bus and have the GPIF continue asserting the same value for several PCLK cycles? As in, if I call DR_DATA during one state, then have a bunch of blank states, will those blank states continue outting the last value set by DR_DATA?

 Hello everyone

Now i meet a problem.I have two (meybe more) boards connect to PC by usb3.0. I want to read/write data with a Application.If just one board I know how to do that.But now two board connect to PC ,and I want to control them at the same time .e.g my device vID= 0x0547&pID = 0x1002
When just one device ,Enumerate like follows and it works well.

int devices = USBDevice->DeviceCount();
int vID, pID;
int d = 0;
do {
USBDevice->Open(d); // Open automatically calls Close() if necessary
vID = USBDevice->VendorID;
pID = USBDevice->ProductID;
d++;
} while ((d < devices ) && (vID != 0x0547) && (pID != 0x1002)); 

but now it has two device and has the same pID&vID.How can I Enumerate them.Can you give me a example 

Best Regards
Thanks

 I want to import a .brd file from the Cypress FX3 development board in to Altium. Let me sum up the things I tried.

     ·              I have Allegro PCB designer installed    

     ·              I tried this: http://www.edaboard.com/thread232557.html    

     ·              I tried this: http://wiki.altium.com/display/ADOH/Moving+to+Altium+Designer+from+Cadence+Allegro+PCB+Editor
    
         

But I keep getting errors and did not succeed in converting the .brd file. Now what I want to ask if someone else can convert the file for me? Or better has another solution for this problem. Or does anyone has the component of the FX3 chip in Altium?     

Thanks,

 Hi 

I have some error in AN75779 firmware eclipse. 

When i build  USBVideoClass project, undefined reference to 'cyu3puartinit'  'jump' ..., errors happen. 

So i can't build this project. How can i do?

I am al litte confused regardig the flags and their connection to the threads of the FX3. In the slave FIFO example the FLAG B is a copy of FLAG A and the flag is connected to the current thread. Its not clear to me if there are two threads (one for P to U and one for U to P) or only one thread (the software thread SlFifoAppThread_Entry).

Is it possible to use the FIFO flags like the FX2 controller? I want to use one flag fixed to the OUT endpoint (as empty flag) and one flag fixed to the IN endpoint (as full flag)? In the firmware example I cannot find the connection between the dma channels and the threads (0 to 3). Can you explain it to me? Thanks a lot.

 Hi

I have 3 question about fx3. 

If i use bulkloop example for HD 720p, is bandwidth or speed enough ?

Why bulkloop example have not GPIFdesigner project file?

What case need GPIF desiner?

 Hello.

I am working on redistribution programming stage.

How can I install CYUSB driver when a user install my application?

To to this, at first, I have tried "RUNDLL32.exe SETUAPI.DLL,InstallHinfSection CYUSB3.NT 128 c:\myworkingFolder\cyusb3.inf" on CMD.exe

But it dos not work.

Well-known hardware-dependant softwares such as NVIDIA Graphics and HP Printer software, install their drivers on software installation stage automatically.

I think there is some way to solve this.

Please help. 

Thank you.

The FX2 has the ability to load a short (~140 byte) device descriptor file from EEPROM, which simply instructs the FX2 default bootloader to enumerate with a specific VID/PID for loading firmware from a host via USB. This is different than booting user firmware itself out of I2C -- rather than loading user firmware from the EEPROM, only a device descriptor is stored, and user firmware is loaded from the host. Does the FX3 also include this ability, or is it forced to enumerate with Cypress VID/PID for USB boot? And if it does include this feature, is the format of the required EEPROM image the same (starts with 0xC2, etc.)?

Hi,

I have a problem after the function call CyU3PConnectState(1,CyTrue) of the BulkLpAuto example the fx3 does a reset. The JTAG debugger says reconnect and can not connect to the FX3 until I reset it. If I call the function CyU3PConnectState(1, CyFalse) it does not fail. This is the USB2.0 modus and just the USB3.0 modus fails.

Why? Where is the problem?

Thanks,
