Normally i used header in order to have image information but with IMX412 , it does not work and i  set header size to zero but my information that i filled is contained in the image .

How can i used this header functionnality with IMX412 ?

Is sensor able to manage this functionnality ?

Hello，请问如何自定义GPIF对应的数据总线pin

脚，选八位宽度会自动选择GPIO0-7，而且在GPIF Designer软件中不可更改。

Hello Infineon!

I'm attempting to add CDC ECM and RNDIS to an fx3s, I'm wondering if it's possible to get feedback for when a USB configuration fails and to let FX3S attempt a second configuration?

The idea being that if CDC ECM fails, it then tries configuration 2 which is RNDIS? I know there are no samples for CDC ECM or RNDIS, but is there an example for how to switch configurations on FX3s?

Regards!

Hi,

I'm new to the CYUSB3KIT-003 from Cypress. I've started reading the manuals in order to understand the device, however it seams to become a bit overwhelming.

I'm wondering if it is possible to design a firmware to transfer data through bulk and isochronous endpoints as well as using UART and I2C, all at the same time.

If there are any hints or specific documentation that I should read, please help.

Thank you!

I "read" on this forum how to implement a 24-bit uvc rgb888-based on the AN75779 and followed all the steps for that solution based on the AN75779 YUV2 example, but when I increase it using amcap.exe, I still get a black screen. Attached here is a chip image of the FPGA video stream and a screenshot of the AMCAP.exe. Please help me to solve this problem.

Hi,

I am using the FX3 driver in my device and at some point while running the software, the board has a communication timeout/failure. The code uses multiple threads: a) thread for requesting data from a GPIF endpoint, b) for parsing the data and c) for plotting the data.

What might be the possible cause or event in which the xferdata returns a false value? 

Thanks, 
Michelle

I would like my firmware to be able to work with both USB 2.0 and USB 3.0 but I am having some difficulty writing DMA setup code that works. USB 2.0 has a maximum buffer size of 512 bytes whereas USB 3.0 has a maximum of 16KB. Therefore, USB 2.0 operation, requires I reduce the FX3's buffer size however I am not sure how to access this information when the DMA is getting set up. My understanding is that the CyU3PConnectState API enables the USB connection and after this call I can use CyU3PUsbGetSpeed to get an enum for the current USB speed configuration. However I have my DMA configuration in the CyFxApplnInit with function CyU3PConnectState and when I put the CyU3PConnectState API call before my DMA configuration, I still get CY_U3P_NOT_CONNECTED. Im not sure if it is a timing issue or what. 

What is the best way to modify the DMA buffer size based on the USB connection speed in the CyFxApplnInit function? Are there any examples which do this?

SDK Version is 1.3.4

I refer to KBA225748  to create a Cx3 project, but i can't find cyu3imagesensor.c - C file,

i only can find cyu3imagesensor.h file, this Header file is loacted in SDK lib folder.

How to generate or get cyu3imagesensor.c - C file.

Is FX3 compatible with Android Open Source Platform (AOSP)?

Infineon has specific support for Android with their USB-Serial Bridge Controllers. Reference USB-Serial SDK @ https://www.infineon.com/cms/en/design-support/tools/sdk/usb-controllers-sdk/usb-serial-software-development-kit/

No similar support for Android appears for FX3 SDK @ https://www.infineon.com/cms/en/design-support/tools/sdk/usb-controllers-sdk/ez-usb-fx3-software-development-kit/

An old post on Infineon’s Community from 2017 notes Infineon’s FX3 does not provide any android specific drivers FX3 Cy3014 support android driver? - Infineon Developer Community
