Dear sir,

When I download image to SPI flash (not Micron M25P40,I use ST 25P40 instead of micron M25P40, both of them are compatible and  operation code are same) by USB control center, programming failed, uart info is :

  <   0: Device initialized. Firmware ID: 50 33 58 46 0 47 4F 52

  <   1: Device initialized. Firmware ID: 50 33 58 46 0 47 4F 52

  2   SPI access - addr: 0x0, size: 0x800, pages: 0x8.

Can you give me some advice?

Hello,

Could anyone please share with me some examples of HID integration into a CX3 project?

I am using the CX3 example provided by Cypress for the OV5640. And so far I have been unsuccessfull to correctty add HID support 😞

Thanks,

Ludovic

Hello everyone

I was looking for a way to re-program a firmware into FX3S without changing PMODE and found the 2 stage boot loader. According to KBA90266, the main firmware should not be re-enumerated if it needs to switch back to the bootloader (via CyU3PUsbJumpBackToBooter). Does that mean the only way to use Second Stage Boot Loader should be like the discussion described in this thread How to erase and reprogramming SPI EEPROM without hardware changing involved? ?

I tried the Second Stage Boot Loader(in Cypress\EZ-USB FX3 SDK\1.3\firmware\boot_fw\src) in SDK and in the code I changed CyFx3BootUsbStart (CyTrue, myUsbEventCallback) to CyFx3BootUsbStart (CyFalse, myUsbEventCallback). After programming the .img into SPI FLASH and boot from it, I can program my normal firmware through control center just like the device booting from ROM code boot loader. When my normal firmware was running, can I jump back to the 2 stage boot loader previously programmed into SPI FLASH? Is Second Stage Boot Loader still working? Thank you!

Hello!

I am new to Cypress FX3 and I have some questions.

I found the example where is explained how to implement FPGA configuration in Master SelectMap mode using SPI. Is it possible to configure FPGA in Slave SelectMap mode using GPIF II? If so, could You tell me how to do it, or give an example project? Should I use GPIF II Designer to create my own state machine for configuration interface?

Thank You!

If I want to develop USB3.0 custom device drivers, is there any reference?

In my case, A RGB sensor outputs data to the CYUSB3014, then I want the upper computer accepts RGB data, based on the custom protocol.

Hi,

We have SDR host board with Cypress USB cable connected to PC, In most of the lab machines it works well just by installing cysub3.0 driver.

But the issue here is when we connect to laptop sometimes the "Cypress FX3 USB StreamerExample device" is shown with exclamation yellow mark in device manager.

We tried installing cypressDriver but it did'nt help, Any idea how to fix this issue.

Thanks,

Poorna Chandran
