Hello

About CY4533,  It refers to the file 610-60538-01_CY4533_BCR_EVK_LAYOUT_FABRICATION_DRAWING.pdf.

There are two questions about the pad directly under the part.

Q1) When I read the Gerber, there are electrodes (Φ10.0mil x 3) directly under the parts. Is this specified for the number of VIAs? The question is on page 2/13, which is the part surrounded by the red line in the following VIA.png.

Q2) Is there a specification for the bonding ratio with the electrodes and the solder opening ratio for the square pad directly under the part?  The question is on page 10/13, which is the part surrounded by the red line in the following  PAD.png.

I want to develop C++ application for fx3 bulk transfer IN?

where I need to refer? 

How much data (maximum data) can able to transfer in fx3 in sec? Is any calculation for this?

I want to receive 7,40,54,400 bits from FPGA through FX3.

Hi Cypress,

I now use CYPD4226 & CYPD4236.

In some situations, I want to turn the device into an only USB device without PD.

Can I use API or HPI to close PD communication, but Rd is still Pull Down?

Thanks!

Bluetooth connection to the Raspberry Pi

I am using a CY8CKIT-062-WiFi-BT with ModusToolbox and would like to transfer measurement data to the Raspberry pi.

The possibility from one KIT to another would not be bad either.

I can't find any suitable examples.

AnyCloud BLE Environmental Sending Service is very comprehensive and you cannot see how CySmart accepts the data. 2 bytes are transferred and then?

Must WICED modules still be used in the programs. I would like to use only "ModusToolbox" and its components.

Can one show me examples for the transfer of floating point values via BLE.

thanks

Hi,

I looked at this topic  -https://community.cypress.com/t5/USB-Superspeed-Peripherals/FX3-multiple-descriptors/m-p/81912

and I’m trying to do it also but I’m having trouble with opening the socket,

Is there any chance that you have example of multi endpoint? Or can guide me how to open socket for each of the endpoint?

I want to create FX3 with

• ISOC in and out endpoint
• Interrupt in and out endpoint
• Bulk in and out endpoint

Thanks,

EliW.

I am designing with the CY14V104NA-BA45XIT. I don't see any guidance in the datasheets of app notes about power sequencing. Is there any requirement for enabling and disabling VCC and VCCQ in relation to each other? 

Dear all,     (and @YatheeshD_36)

Almost 18 months ago I was having some issues in using the .Net Api for Cypress EZ-USB FX3 SDK.

However I got some really nice help in this thread:
https://community.infineon.com/t5/USB-Low-Full-High-Speed/SuiteUSB-using-NET-API-for-PassMark-USB-3-0-plug/m-p/76716#233780

The issue was resolved and everything has been running smoothly for the last 18 months until the other day.
What has changed? Nothing obvious that I'm aware of, but our IT department has updated machines with Windows security patches if that could make a difference. 

What seems to happen is the following:

1. The device (Passmark USB3.0) inserted into the machine.
2. My code is using the CyUSB  .Net interface for the CyUsb3.sys driver.
   
3. My code checks that the endpoints are USB 3.0 by checking the size of the MaxPktSize of the endpoint and making sure that it is not below 0x4000.
   

    

4. This is all good. Then my program creates an arbitrary buffer of 65k data and calls the
   endpoint function XferData.
   
5. This fails and if I debug fairly deep down in CyEndPoints.cs (at line 367 in function BeginDataXfer) I can see that _lastError is set to 997. The function returns a true so this might be as expected.
6. After this the function FinishDataXfer is called to get the overlapped result.  However the rResult from the GetOverlappedResult function returns false and the len is set to 0 bytes.
7. No bytes are being transmitted.
8. One observation is that after the device was inserted the Cypress Control Center reports a descriptor info with a Bulk channel with MaxPktSize of 16384.
   
9. After the transmittal failure the device info reports just a bulk channel of 1024 bytes (which is what I interpret as HS instead of SS)
   
10. However the device still seems to be enumerated at SS from what it will let you know through its display.
    

    (The Passmark testprogram does not show any errors and happily runs at SuperSpeed (USB3.0))

• There have been no code changes for my code. 
• From what I can tell there are no updates to the Cypress / Infineon SDK (EZ-USB FX3 SDK 1.3.4 for Windows)
• There are no updates to the FW of the Passmark adapter nor to their driver during the last 18 months.

If someone has any idea what I should try to look further into, or has any advice on how to move forward,  it would be greatly appreciated.

King regards
Magnus

• Hardware

  • host: tinker board 2s(rk3399)，kernel 5.13

  • slave: sg130gs(1280*720, YUYV, 30fps) + fpga(spartan 6) + cyusb3014, isochronous mode

• Problem

  • Run this script on host

    #!/bin/bash
    ​
    while : 
    do
            yavta -c30 /dev/video0
            sleep 2
            yavta -c30 /dev/video1
            sleep 2
    done

  • After random time(from minutes to hours), one of these cameras would be stuck

  • USB packets captured by tcpdump indicate that the host keeps polling(isochronous) the slave while the slave keeps responding with a data packet with zero-length

  • After this, if I restart the test script, the device that is stuck will be missed

• some trials on other settings also failed

  • ov5640(1280*720, YUYV,30fps) + cyusb3014, bulk mode

  • sg130gs(1280*720, YUYV, 30fps) + fpga(spartan 6) + cyusb3014, bulk mode

• In addition, test with a single camera is fine

Any ideas? thanks

Hi,

I was looking for the proper way to assign a different custom serial numbers using the same firmware image without having to compile a different firmware image for every device and I followed the steps explained below thread.

https://community.infineon.com/t5/USB-Superspeed-Peripherals/FX3-Serial-number/m-p/95991#M7831

I was able to add serial number to firmware but when I used SerialNumberGenerater application to create different serial numbers, we couldn't use those newly generated firmware images to flash the device since it gave an error for all the image files created by SerialNumberGenerater application.

I looked into SerialNumberGenerater application and investigated the created .img files using hex file reader and it seems that the serial number was assigned in a correct way but still gave me an error when tried to flash it. 

I did some more investigation and did another test. I created two firmware image with different serial numbers and checked the differences between .img files and I realized not only the serial numbers needs to be changed but also the last 4 hex values were different! Why is that happening? maybe checksum/md5 hash?

Since SerialNumberGenerater application only changes the serial number values in the firmware image file, how can we overcome this problem? How can I assign a different custom serial numbers using the same firmware image without having to compile a different firmware image?

Thanks in advance,

Irfan
