Dear Sir,

The FX3 support 32 bit GPIF II interface.we are using GPIF Designer 1.0 to Draw interface and state machine diagram.in interface there are only 8,16,24,32 selection for GPIF data bus width.but i need 12 GPIF data bus.please help for selection 12 Bit GPIF data bus.

Thanking you

Best Regards,

Hi, is there a Streamer application for Linux available like the one that is provided for Windows with the SDK 1.3 to test continuous throughput ? Any help as highly appreciated!

I have a project that was build for the FX2LP in Keil uVision C51, and now I am trying to build, compile and use that same program on the FX3.  I have followed all the online instructions for the MDK-ARM plugin, and need to know if there are more things I am missing.  I'm sure there are, however if there are libraries, configuration settings, possibly using MinGW or PATH changes?  Any help would be amazing.

I dont know if there is a way to reset the fx3 device without disconnecting from the usb host. Just doing a usb stack reset, is there any way to achive that?, I noticed in my application that works for the very first Gpif2 transaction but after that, and after reset the dma channel, endpoint, etc there is no way to take the app works again, sometimes its works 3 times, sometimes 8 times, but finally it crash. So again anybody know a safe way to restore the device and the usb stack to initial condition, thanks.

(I follow the lines includes in the troubleshotting guide about the way to reset dma channel keeping the endpoint in nak state.)

I would like to operate the slavefifo_examples program to 32bit.
 
#define CY_FX_SLFIFO_GPIF_16_32BIT_CONF_SELECT (1)
 
1. Set as shown above in the code, also compiled using the FX3 SDK
2. Run the compiled images from the test board.
3. Check the return data from a function CyU3PGpifLoad
    apiRetStatus = CyU3PGpifLoad(&Sync_Slave_Fifo_2Bit_CyFxGpifConfig);
 
SDK ver 1.3.1 : CY_U3P_SUCCESS
SDK ver 1.3.3 : CY_U3P_ERROR_NOT_SUPPORTED   /* if a 32 bit GPIF configuration is being used on a part that does not support this */
 
In order to use 32bit FX3 SDK v1.3.3, Is there a need to set up?
Will that make any difference to the library 1.3.1 and 1.3.3?
 
Library folder "C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\u3p_firmware\lib" of files, "ver 1.3.1" if the file to be replaced, CY_U3P_SUCCESS the return will be.
 
cy_as0260.a
cy_ov5640.a
cyfxapi.a
cyu3lpp.a
cyu3mipicsi.a
cyu3sport.a
cyu3threadx.a

thank you.

Hello,

I am reading data of a parallel 16 bit ADC through the FX3's GPIF. It seems to work fine as I observe different values in the Streamer for different input signals.

However I haven't figured out yet, how to obtain the ADC's 16 bit values from the hexadecimal data which is displayed in the Streamer.

For example: Without applying any signals to the GPIF I get something like this:

3FB0 EE FF FF 7D EE FF FF 7D EE FF FF 7D EE FF FF 7D
3FC0 EE FF FF 7D EE FF FF 7D EE FF FF 7D EE FF FF 7D
3FD0 EE FF FF 7D EE FF FF 7D EE FF FF 7D EE FF FF 7D
3FE0 EE FF FF 7D EE FF FF 7D EE FF FF 7D EE FF FF 7D
3FF0 EE FF FF 7D EE FF FF 7D EE FF FF 7D EE FF FF 7D

Is there any application note describing how to deal with the data ?

Thanks a lot

Does anyone know how many bytes are transferred to the explorer kit board through SPI when I load the " USBSPIDMAMODE" .img file?

Hi

I using UVC with image sensor.

Is it possible  16bit bus swap in 8bit-data mode (not using 16bit-data)?

ex)  D0 ~ D7 <-> D8 ~ D15  , swap data.

Is it possible  with gpif designer or firmware coding  ?

If I were trying to set up the FX3 to have a EEPROM on i2c, an FPGA and SPI flash chip both set up on SPI, how and what files would I need to include in my project to enable the set up of the DMA to manage this?  Does the uC even need to interact with the interfaces, or can the DMA manage it on its own?

What is the thermal resistance between the junction and the case (Theta-JC) and the junction and the board (Theta-JB) for the FX3 121-ball BGA package?
