Hi,

On board, FX3 main clock is supplied by external 19.2MHz crystal and FSCL[2:0] is connected to gnd to select 19.2MHz crystal.

Want to configure FX3 as master and generate clock for slave FPGA on PIN J6(GPIO[16]).

1. How to set GPIF output clock frequency?

2. Once it's set, all GPIOs are working at this clock frequency?

Thanks!

I'm using CX3 RDK and  MIPI Sensor that has 2 lines embedded data soon after frame start.

Currently, MIPI IF is working and DMA get/commit buffer(CyU3PDmaMultiChannelGetBuffer/CyU3PDmaMultiChannelGetBuffer)

seems working.

However, there are embedde data on 1st packet of each frame when I check usb packet by protocol analyzer.

I would like to get only image data(RAW12/RAW10) by CyU3PDmaMultiChannelGetBuffer.

I asked sensor vendor how to disable embedded data output.

Their answer was "no way".

Since CX3's GPIF II state machine is fixed-function,

Are there any way to ignore/filter embedded data(Data type:0x12) by CX3 MIPI Rx block?

Thanks,

Shuji

Hi,

I'm referencing SlaveFifoSync firmware.

In cyfxslfifosync.c, line 887, it's enable GPIO 59 as below.

    /* No GPIOs are enabled. */

    io_cfg.gpioSimpleEn[0]  = 0;

    io_cfg.gpioSimpleEn[1]  = 0x08000000; /* GPIO 59 */

    io_cfg.gpioComplexEn[0] = 0;

    io_cfg.gpioComplexEn[1] = 0;

My questions are

1. Why GPIO 59 is enabled? Since I can't find it from GPIF Designer.

2. What's the general guiding rules for GPIO initialisation.

Thanks!

Hello,

I am using Denebola board for our development. But I am not able to Flash that binary into Denebola board. To flash firmware into Denebola board we refer "Firmware_build manual.pdf" but still I am not able to flash that binary into the board. When we open USB Control Center from FX3 sdk we are not able to select device type from that panel. I attached screen shot of same please let me how to solve this issue.

Thanks,

Amit

Hi All,

I have some boards that I forgot to make connections to the CX3's PMODE pins.  As you'd expect I don't seem to be able to load code in the boards.  I did however, add a CY7C65215 to the board as a programming interface.  This chip is wired to the TMS pins as well as the CYUSB3064's RX & TX pins.  Can this interface access the CX3's programming interface?

Thanks,

Scott

If I use the ControlCenter Program->FX3->I2C EEPROM it successfully loads that img to the EEPROM. I want to know how to write my own code to do exactly that. I have tried enmResult = fx3Device->DownloadFw(("cyfxusbspidmamode_EEPROM.img"), I2CE2PROM); It always returns failed. I have tried enmResult = fx3Device->DownloadFw(("cyfxusbspidmamode_EEPROM.img"), RAM); This is always successful, but the EEPROM never gets programmed.

CCyFX3Device *fx3Device = new CCyFX3Device();

FX3_FWDWNLOAD_ERROR_CODE enmResult = FAILED;

Hi,

As per the datasheet of CYUSB3035, this devices supports an SPI master interface as mentioned below:

FX3S supports an SPI Master interface on the Serial Peripherals port. The maximum operation frequency is 33 MHz. The SPI controller supports four modes of SPI communication with the Start-Stop clock. This controller is a single-master controller with a single automated SSN control. It supports transaction sizes ranging from 4 bits to 32 bits.

Can you please let me know how many slaves it can support over SPI interface? I am already using 2 slaves on SPI interface. Can I add 2 more SPI slaves?

Thanks & Regards,

Sunny Watts
