Are SPI pins tristated until the start of configuring FPGA in AN84868? If no configration data are sent to FX3, will the spi pins stay tristated?

Hello,

Is there a way to set the (Serial Number) SN in the device properties it is currently set to nothing.

With an USB3 device using the cypress FX3 we face the situation where the devices RTS state machine gets out of sync with the hosts state machine during restart of the system: While the device goes from 'U1' to 'U2' state the host changes into 'Polling.LFPS' state (see attached USB trace). As consequence the device is not operational.

As Host platform we use a PC with Intel i7-6700 with xHCI root hub running Win 10; The USB LPM power option is set to 'Moderat power settings'.

Observations:

To eliminate the problem we can change the LPM power options in Windows to "Off" - as this is a modification on host side this is not a preferred solution.

Also preventing the transition from 'U1' to 'U2' state (by returning CyFalse in LPMRequestCallback when 'U2' is requested) eliminates the problem - but then complience to USB Chapter 9 is lost.

Question:

How can we get our device operate reliably with the host when the LPM power options is set to 'Moderat power settings' which is the default configuration in Win 10?

Hi,

It seems to have some restrictions around the FX3 internal clocks. For example, there is a mention about DMA overflow in some cases if we decrease the internals clocks. The main problem here is we want to decrease the power consumption of the FX3 (each mA counts!). For this particular design, we will operate only in USB 2.0. Does anybody has some experience about safe settings for internal clocks of the FX3? (CPU, DMA clocks?)

Thanks,

Denis.

Hi

This is first time to make USB device by FX3.

I make a board that create A/D data on FPGA and send though FX3 to PC.

I succeed to make a data on FPGA, and receive data from FPGA.

but, transfer trigger is made by PC host software.

So if i want to receive data, always click the Receive button on my C# host program.

I want to make send trigger signal by External device, when A/D conversion is ended.

(The time interval between each A/D conversion is not same. ) .

Is it possible with interrupt endpoint?

If can, how can i detect the trigger signal from external device on PC Software?

I am trying to communicate to an enclustra FPGA development board through USB. The device shows up in the Windows 10 device manager as FX3 with an exclamation mark.

I have tried to go to windows 10 device manager, find the FX3 that shows under "other devices" with an exclamation mark. Right click and select "update driver" then "browse my computer for driver software" point it to the folder that has the cyusb3.inf as well as cyusb3.sys in it and click "next". Then I get the following message: "Windows was unable to install your FX3" "Windows could not find drivers for your device..."

My windows version is: Windows 10 64 bit, Version 1803, OS Build 17134.137

I installed Cypress FX3SDKSetup_1.3.4 and pointed to the windows 10 64 bit driver folder to find cyusb.inf and cyusb3.sys

Everything was working fine under windows 7 but my PC crashed and I can not go back to that.

I appreciate any help I can get.

I have an application processor which is interfaced to the Cypress FX3 chip via memory controller. My job is to access the S-Port via the P-Port, configure it and perform R/W to an SD card connected to the SIB0. I have been able to initialize the card successfully. So I know that the SD command interface is working. Now I have to perform block R/W from/to the SD card, and I'm stuck here because the S-Port does not support any FIFO interface(please correct me if I'm wrong). I've looked at the reference code and in that code, I see that the S-Port is interfaced with the DMA. Please note that in my case, doing DMA will be complicated and very inefficient because the data buffer(read or write) is stored in the application processor and cannot be passed directly to the FX3s. Therefore, if I have something to write to the SD card via DMA, I will firstly have to copy the buffer from the application processor to the FX3s internal memory and then initiate a write via DMA. Please note that this is very inefficient. Another thing that I can do is transfer data byte by byte via the CMD52 interface. Apart from being slow and undesirable, it does not allow to transfer more than 16 bytes at a time and requires a new command for every byte transfer. The Application processor and the FX3s don't have any shared memory and therefore the above mentioned mechanisms are the only possible.

Back to the original question: I can get rid of all this if the S-Port has a FIFO R/W register. With that, I can trigger a CMD53 and continuously perform R/W on that register based on some condition. That would make my implementation simpler and faster. In the reference manual, I do not see any such register but the reference manual seems to be not complete anyway so I think its best if I ask this question on the forum. Hopefully I'll have answer to this question very soon.

I would like to debug FX3 on Ubuntu 16.04 LTS.

I use the latest SDK 1.3.3.

I have a problem with openocd:

The same error is returned inside ezUsbSuite trying to launch openocd.

If I understand correctly, openocd detects USB-Serial device correctly.

Hi, I have some questions about AN75779.

And no video display ......What causes this phenomenon? How can I solve this problem.

Good evening!

I have wired FX3S to a microSD socket consistent with the diagram in FX3S 4-Wire microSD PCB Design ??? . Though low voltage (1.8v) was considered in this thread, 3.3v was used consistent with the image.

The SD card is initialized as simply as possible, and without error, a la

CyU3PSibIntfParams_t intfParams;

intfParams.resetGpio       = 0xFF;           

intfParams.rstActHigh      = CyTrue;         

intfParams.cardDetType     = CY_U3P_SIB_DETECT_NONE;

intfParams.voltageSwGpio   = 0xFF;                

intfParams.lvGpioState     = CyFalse;                     

intfParams.writeProtEnable = CyFalse;                  

intfParams.lowVoltage      = CyFalse;       

intfParams.useDdr          = CyFalse;    

intfParams.maxFreq         = CY_U3P_SIB_FREQ_26MHZ;  

intfParams.cardInitDelay   = 0;                      

errno1 = CyU3PSibSetIntfParams (0, &intfParams);

errno1 |= CyU3PSibStart ()

However, attempting to query the device always yields error 0x68

static CyU3PSibDevInfo_t   glDevInfo;          /* Structure to hold device info */

errno3 = CyU3PSibQueryDevice (0, &glDevInfo);

Am I overlooking something simple?

TIA
