USB superspeed peripherals Forum Discussions

Hi:

 I use the FX3 to connect to a FPGA,i use the ‘sync_slave_fifo_2bit’GPIF project to communicate with FPGA.The dma channel is set usb_socket1 to the p_port_socket_1,it can be tansfer data from PC to FPGA,but i want to transfer somedata to the DMA channeel in the fireware and whitnot the PC.

Hi:

I use the FX3 to tranfer data from PC host to a external device.I want  to know how to get the fastest speed? How to set the endpoint and DMA channel?

Please tell me 

Thanks a lot.

Hi Cypress, 

I am compiling the reference design but encounter the following error. 

It appears the version of the libgcc.a is missing. 

What can I do now? 

Thank you!

Hello

I use FX3S chip. I want to transfer some data PC to FPGA.

I set FX3s Master mode. and  I want to use 16 bit AD MUX mode.

And I set DMA type is Auto.

I check FPGA side. Fx3 send Addresses both ALE timing WE timing.

Timing Diagram cycles are seen exactly working. Address send on ALE timing and Data send on WE timing.

ALE timing and WE timing are same data in the FPGA side.

What can I do?

Regards

Shin.

Hi:

 I am use the FX3 as a usb controller to connect to a FPGA.I want to konw how to set DMA and endpoint that the pc host can transfer data to FPGA with the fast speed.Is the endpoint brust or streams?Can i set some dma channels to transfer data which is the whole?

Hi all,

is there a specific API function to put the attached eMMC device in low-power mode and restore (sleep/awake CMD5 command)?

Can you provvide an example?

Thanks a lot!

I want to choose cyusb3.0 emmc to make a customer udisk solution.

But I can't find any detail information from datasheet.

Can cypress send me one?

Hello,

mine design progresses and the next challenge is the correct understanding of supply to the chip supply CYUSB3014. The Kit EZ-USB FX3  powered by USB bus or external power supply, such as the Spartan S601 Kit. My design has its own supply chain, all the necessary 5 V, 3.3 and 1.2 volts. In datasheet "EZ-USB FX3 Technical Reference Manual" on page 94 says: "1. Wait for a valid VBus voltage" and "Any PHYs that are enabled need to be disabled when the VBus voltage is removed. The entire previous procedure needs to be repeated when valid VBus is detected again" and "Note that USB 3.0 PHY on the FX3 needs to be turned off when VBus is removed or a host disconnect is discovered by other means. If the 3.0 PHY is left turned on, the 3.0 link startup is liable to fail when connected again to the host." What correctly is that mean? Can I supply only pin VBUS or VBATT (or both) from USB bus to comply with these requirements disable PHY when the device is not connected to USB, but other voltages (VIO[1..5], CVDDQ, VDD, AVDD, U3TXVDDQ/U3RXVDDQ) take from my power chain all time without interruption? Or I must take all voltages from VBUS by means of LDOs like in EZ-USB FX3 reference schematic?
