Hi,
I'm trying to test the USB3 technology with the Superspeed Explorer Kit (CYUSB3KIT-003), the FMC interconnect board(CYUSB3ACC-005) and the xilinx kintex developement kit KC705.
I was able to run the the default streaming example in stand alone (only the CYUSBkit) without issue.
I was also able to to run the AN65974/SF_loopback.img example in the FX3 and my code in the xilinx FPGA.
However, if i try any other file at the same location the test failed (BULK IN transfer failed with Error Code:997)
I would like to know why?
I also did try to recompile myself the FX3 FW.
I builded in release the slfifosync example found there "C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\slavefifo_examples"
The Stream In work in Control center but the throughtput in Streamer.exe is very slow(32000KB/s) or have error depending on the packets and Xfer configuration.
When i do recompile the same code in 32 bit mode CY_FX_SLFIFO_GPIF_16_32BIT_CONF_SELECT(1) and program the FX3 in RAM after a reset with the KC705 at off, the device won't enumerate in control center. So there is no way I can test a streamer program in my FPGA with a 32 bits interface.
Anyone know how to fix those issues?
Thanks
JeanAlexis

HI,
I did try to narrow down the issue using the OOpenOCD debbuger in eclipse.
Using break point I did find the fonction that returned with error in cyfxslfifosync.c
/* Load the GPIF configuration for Slave FIFO sync mode. */
apiRetStatus = CyU3PGpifLoad (&Sync_Slave_Fifo_2Bit_CyFxGpifConfig);
if (apiRetStatus != CY_U3P_SUCCESS)
{
CyU3PDebugPrint (4, "CyU3PGpifLoad failed, Error Code = %d\n",apiRetStatus);
CyFxAppErrorHandler(apiRetStatus);
}
The apiRetStatus value was 70 so the error code was : CY_U3P_ERROR_NOT_SUPPORTED
The description say CY_U3P_ERROR_NOT_SUPPORTED - if a 32 bit GPIF configuration is being used on a part that does not support this.\n
I would like to know why i got this error?
To my knowledge the superspeed devkit do support 32bits GPIF operation.
Regards,
Jean-Alexis

Hi Jean-Alexis,
FX3 supports 32-bit GPIF configuration.
Please make sure to disconnect the PMODE[2:0] pins of the connector on the interconnect board. This is to ensure that device comes up as FX3 Bootloader.
Or else you need to connect the FPGA after programming FX3.
