Hello,

I have implemented CDC USB class in fx2lp.I have programmed to program->fx2->64k EEPROM.when its programmed to eeprom,its detecting as USB SERIAL PORT under COM PORT.

Again i need to program this fx2lp device,but its not detecting in the default control center.

what is the possibility to program this device again?

We are migrating from FX2LP to FX3. I have following questions related to this project:

1. We used IBN (Interrupt Bulk NAK) in FX2LP. Do we have this interrupt in FX3?

2. We are using an Aptina Sensor with your FX3 dev kit. But we are having issues running the Bulk mode example on Linux. We are using a small board computer like raspberry pi. We would like to test the isochronous mode with the Aptina Sensor. Do you guys have example that shows interfacing Aptina Sensor with the dev kit in isochronous mode?

Hello,

I am using cyusb3035 fx3s and FX3 slavefifo firmware.the firmware is in vendor class.if i modified this to UVC class,can i store this UVC data(data coming from fpga+UVC headers) in the sdcard storage(p port to s port)?

Hi, I have been working with two FX3 devices integrated in an USB 3.0 Hub (TUSB8043RGCT).

A MUX(PI3USB302-AZBEX) is used to select the 3.0 lines of the Type C port, as shown in the block diagram.

When the Type C cable was inserted in direct connection, the CyU3PUsbGetSpeed() API returns 3 (denoting USB 3.0 connection).

When the Type C cable was connected inversely, initially it should be enumerated as USB 2.0 device and further upon switching the MUX, it should be convert into USB 3.0 device.

But in the inverted type C connection, the CyU3PUsbGetSpeed() API returns 0 (denoting no USB device connected).

Can anyone help me with this issue?

In the CX3 application note "CX3 Hardware: Frequently Asked Questions - KBA91295" it states that it needs an external 32kHz if you want to use the watchdog feature, but in the datasheet it says that the external clock is optional for the watchdog.

Which is correct?

I want to enable all the camera control listed in the attached image.what all changes I have to do in the fx3 firmware.

Hello,

I am trying to debug the USBBulkSourceSinkLED project of CYUSB3KIT003 with OpenOCD in SDK1.3.4.

but, I had an error like below.

I set the "Run Configuratins" like below.

The "arm926ejs_fx3.cfg" file is in the folder below.

C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\JTAG\OpenOCD\Config

What shall I do?

Best regards,

Hi, can the GPIF II of the FX3 be configured such that two masters (each 16bit data) can write simultaneously to the FIFO?
