USB superspeed peripherals Forum Discussions

I am using CYUSB2014-BZXC microcontroller and configured the microcontroller to boot from SPI Flash with usb fallback. When I program the device RAM , everything works as expected. However when I program the Flash , the microcontroller does not appear as a USB device in the operating system (a camera in my case) and I can no longer program the flash nor the RAM. I am using  S25FS064SAGMFV010 as Flash. I followed the recomendations on choosing the Flash and did everything according to AN70707 EZ-USB FX3/FX3S Hardware Design Guidelines and Schematic Checklist and according to  AN76405-EZ-USB FX3/FX3S boot options. However when I compared the recommendations to the FX3-DVK-BOARD-DEVICE_REV3 board schematics I noticed that in FX3-DVK-BOARD-DEVICE_REV3 MOSI and MISO Pins are pulled up, while in the recommendations this is not advised. I do not really know what is going on. I built the code for SPI flash with the following post build command elf2img.exe -i ${ProjName}.elf -o ${ProjName}_SPI.img -v -i2cconf 0x00  with elf2img.exe being in the Debug folder. Part of the schematic of my board is attached.

Hello, I'm writing a code on DFU  for FX3,then I got stuck with a process named DETACH-ATTACH sequence,

what is DETACH-ATTCAH sequence and how to implement it in FX3?

Thank You.

I did the GPIF interface test through "SlaveFifoSync" Example Code.

The DMA size of FX3 was set to 16384 and the count was set to 6.

The FPGA sent 16384 bytes 10 times at 150us intervals through the GPIF interface to FX3.

I sent GPIF data referring to the Figure4 Write Sequence of the AN65974 document.

And I received GPIF data using the application "bulkloop" provided when installing the FX3 SDK on my PC.

I think we should receive data 10 from the application. However, I only received data 6 times.

It was confirmed that FX3 caused an error of "CYU3P_PIB_ERR_THR0_WR_OVERRUN" during debugging.

There was no "CYU3P_PIB_ERR_THR0_WR_OVERRUN" error when sending data 6 times from FPGA to FX3, and there was always an error when sending more than 7 times. I think this error occurs because the DMA count is set to 6.

And this is my questions.

If I write GPIF data from FPGA to FX3 and read the data from application, buffer will be empty, but I don't know why the "CYU3P_PIB_ERR_THR0_WR_OVERRUN" error occurs. And I wonder what I should do to avoid the above error.

Hello,

I have bought the book and CYUSB3KIT-003, but I can't find the example software projects that the book is referring to. Where could I find files such as "Chapter3Example1.img"?

I couldn't find them from the book's page or in the code examples:

https://www.cypress.com/documentation/other-resources/superspeed-device-design-example-john-hyde

https://www.cypress.com/documentation/code-examples/usb-superspeed-code-examples

Dear All,

We are using CYUSB3KIT-003 development kit and we want to add file system (FAT) to the device. So that it will detect as device when we connect to any OS.

So how to add file system to the CYUSB3KIT-003?

I have Olimex ARM-USB-OCD-H debuger and I want to debug FX3 device placed on my DevBoard.

I use Cypress EZ USB Suite.

I installed OpenOCD 0.6.1 as in the example (12.2.1.2 FX3 Programmers manual) and created ezusb_fx3.cfg file.

I installed drivers for Olimex ARM-USB-OCD-H using Zadig 2.4.exe.

How to fix this problem and begin debug DevBoard?

Hi,

I'm looking for a contractor to develop a driver to run On-Semi AR0144 image sensor over FX3.

Will pay for that of course.

Developer must have previous experience with develop image sensor drivers on FX3.

Develop a driver for the AR0144 will be an advantage.

I will send detailed description/requirements upon demand.

Thanks,

Itay

Hi, I have a question about EZ-USB® GX3™ Hardware Design Guidelines file. I'm reading the document, and I have found this:

I have searched the EEPROM components but, on this datasheet (https://www.mouser.es/datasheet/2/268/21794b-74044.pdf) A model is 8-bit and B model is 16 bit. Is this a errata?

Dear Sir,

I am using CYUSB3014 to develop a camera. Now it works normally at USB3.0 mode. But if I connect it to the USB2.0 port, it does not work well.

In high speed mode(USB2.0), when I read a value from the device, it always have a unbelieve delay, even if in the firmware I return a fake value when receive the request.

For example, By bushound, I can monitor the time. If I send out the request at 15:01:26:540, then after about 13 millisecond, I will get the fake return value at 15:01:26:553. But in Super speed mode(USB3.0), the fake value will be reported at the same time or only need 1 millisecond.

Does anyone know what happened?

Thanks

Chad

Hello,

Board : CYUSB3KIT - 003

I'm trying to test my DUT(Device under test) machine with lower packet size then 1024 with the FX3 board and the "USBIntrSourceSink" firmware example.

I want to change the parameters inside the "USBIntrSourceSink" firmware example according to the USB 3.2 Specification limit.

1. maximum packet size.   (USB 3.2 Specification 4.4.7.1, 9.6.6)
2. BURST SIZE.

Inside the "USBIntrSourceSink" example there are

• cyfxintrsrcsink.c
• cyfxintrsrcsink.h
• cyfxintrdscr.c

In "cyfxintrsrcsink.h" I changed the "CY_FX_INTR_BURST_SIZE" param to 1

And inside "cyfxintrsrcsink.c"

 I changed size to 8

------------------------------------------

case  CY_U3P_SUPER_SPEED:

            size = 8;

            break;

------------------------------------------

Also inside "cyfxintrdscr.c" in section

/* Standard super speed configuration descriptor */

 I change it to

-------------------------------------------------------------------------------------------------------------

    0x08,0x00,                      /* Max packet size = 1024 bytes */

    0x08,(0x00 * CY_FX_INTR_BURST_SIZE), /* Bytes per interval : 1024 * burst */

-------------------------------------------------------------------------------------------------------------

the FX3 board don’t pass the enumeration and fail in the Descriptor hand shake.

But when I change the number to 16 in all the files it works And the streamer can test the FX3 board with the interrupt firmware test.

Thanke for your help.
