I cannot make JTAG debug working for CX3, though I followed the instrinctions reported in the EZUSB user guide. t looks like that EZUSB can communicate with the segger but cannot make the CX3 ANR9 entering into debug mode

Connecting to J-Link...

J-Link is connected.

Firmware: J-Link V10 compiled Dec 11 2019 17:11:27

Hardware: V10.10

S/N: 260108561

OEM: SEGGER-EDU

Feature(s): FlashBP, GDB

Checking target voltage...

Connecting to target failed. Connected correctly?

GDB Server will be closed...

Shutting down...

Could not connect to target.

Please check power, connection and settings.

This should drive to wrong connections from the J'Link probe to the hw but I checked this (the customer board is a replica of the econ danebola board and the JTAG lines go straight from/to the CX3 MCU. Any Idea on what may be wrong?

I have a question which is more related to eclipse: the default behavior of the run / Debug button is 'Debug Local C/C++ application' which results in errors (the elf file is considered as a windows application )

How can I change this behaviour? I deleted the C/C++ app from 'Debug as' list, but this did not help

Thanks much

Two CYUSB3KIT-003 stacked, each connected to PC host, what is the best bulk transfer rate?

My calculate: 100MHz*16bit bus=200MB/s with like 10-20MB/s overhead loss, can this be achieved?

Hello,

I am transferring data from FPGA to FX3.But the thing is in waveform the signals are not triggering for data transfer.I am using flag A&B as active low and the flags are always high throughout the data transfer.And in FX3 side i am using firmware(P to S0) I am not getting where will be the problem.The problem is with FPGA or FX3 or GPIF II Interface Any one knew the solution for this?

The steps I am following to do data transfer:

1.Programming FX3 with.img file.

2.Programming FPGA with .bin file.

3.Checking flags and signals in traces

4.Checking Consumer Events.

Regards,

Srujana.

Hi,
I have a question on this article:
Drive Multiple GPIO Pins Simultaneously in FX3™ - KBA212557

I need to produce 2 simultaneously output (somehow SPI in high freq) : CLK up to 28.8MHz and MOSI which should be synchronized with an input clock to FX3

I am wondering that if I use from the mentioned article, Can I get this frequency on gpio?
As in Increasing Frequency of Bit-Banged GPIO Clock in EZ-USB® FX3™ - KBA90267 , there is a limitation for frequency range.

If no, how can i get these signals from Fx3 without using GPIF II?  I have only 3 pins free on FPGA and no more for using GPIF II.

Thanks

Hello guys,

We would like to develop our custom PC software that will communicate with UVC class device. We strongly believe application note AN75779 ​is great starting point for us.

To the best of my understanding, in order to play video streams from Aptina MT9M114 sensor board with VLC player, we would need the following pieces of hardware:

1. CYUSB3KIT-003 development kit
2. Aptina MT9M114 Image Sensor Baord
3. Adapter board for connecting Aptina sensor with USB3 Kit

Would you, guys, be so kind to confirm that the above list is all we need?

Thank you very much for your time and efforts.

Sincerely,

Bojan.

Dear All，

      we have finished UVC+CDC with FX3，and we can install the uart driver with *.inf file step by step。

      but how to make a driver（such as *.exe） for our CDC device，we want to install the driver easily in Windows like other USB-UART products。

HI

使用“usb control center”同一个固件烧录SPI【M25P40】，CYPUSB3014BZXI  烧录提醒"programming of spi flash succeeded"但无法枚举成UVC，重新上电依旧识别“CypressFX3 usb bootloader device”  上电期间示波器探测SPI-MCLK没有波形。

但是CYPUSB3014BZXC可正常启动并识别UVC，PMOD已经确认是SPI状态，2份原理图是一样。工业级与消费级上电期间读SPI的命令有差异？

thank help me ，thank you！
