Control NAND Flash Memory with FX-3　？

Is there a document on connection examples?

Fx3でSLC NAND Flash Memoryをコントロールしたいです？
しかし接続が解りません。資料ありませんか？

I'm planning to implement the 24 bit GPIF II interface with FPGA . In order to use the SPI port with 24 bit mode i need to know the exact mapping GPIO with 24 bit data lines[DQ 0:24]. From the datasheet provided for FX3 first 16 pins (GPIO 0:15) mapping are common for 16bit /24bit / 32bit.  The GPIO mapping for DQ[17:23] for 24 bit GPIF is not provided in the datasheet.

Thanks,

hello everyone,

                        We are doing slavefifo intrface with the Fpga ,we want add the UVC Class . our requirement is to keep the UVC Class To fetch data from FPGA And one end point which is bulk OUt(for sending the data from pc to fx3) in the Control center .

can any one did this please help me .

best regards

Hi,

i was able to use the COM debug port since I installed the FX3 SDK. However suddenly there is no  debug COM port anymore.

I can see the three USB-Serial devices listed on Devices-USB (Vendor 1, Vendor 2, MFG)  but there is no COM port on Devices-COM Ports.

All I remember I was trying to add the I2C UART port, in order to have two serial ports. Since then i cannot see any COM port.To configure I2C UART port I installed "USB Serial Kit". Might this have any adverse effect on COM port setup? (I have tried to uninstall Serial USB kit with no positve results).

Any way to fix this?

Hello,

I am using the USB3 Development Kit by Lattice (Lattice USB3 Video Bridge Development Kit - Lattice Semiconductor ). I plan to connect it ultimatly to a raspberry Pi in order to Stream the HDMI Input.

While I am able to run it without any Problems as a videoinput on a Windows Device, it wont work with any Linux Device I tried.

I configured the CX3 output to 640x480p@60Hz. It was possible to use the Windows USB 2.0 Port with.

First I tried to get it work directly with the Rapberry Pi 3b+ running Raspbian (debian stretch), where it lists as video input ( $ ls /dev/video* ) but is not possible to use any further.

Second I tried to connect the Development Kit on PC running Ubuntu 16.04, here it is not even recognized as a video Input. Am I missing drivers?

I always though, anything with the cx3 should run "out of the box" if it is configured as a UVC-Device?

As I said, I would really like to get it working with the Raspberry Pi, but maybe its easier to start with the PC?

Best Regards,

Vitus
