Hi,

I'm Jheison Mejia, I'm new in this topic. I have been using Xilinx development boards for prototyping. Currently the ML-501. Which has a Cypress Semiconductor CY7C87300-100 AXI.

When I conect it via "USB 2.0", Windows showed me a message telling me the dirver wasn't found. I was searching this driver but no solution seems to be available.

I'm using Windows 7, 32-bits.

Regards

Sorry it's the CY7C67300-100AXI.

Not CY7C87300-100AXI.

 Hi,

   Please see http://www.cypress.com/?id=4&rID=39486. Modify inf file for your VID/PID.

Thanks

Hi Prajith,

Thanks for the answer but it doesn't work :(

I downloaded and installed the CySuiteUSB_3_4_7_B204.exe. I added the VID and PID in the .inf file before binding the driver to the device. I followed step by step the section "Matching Devices to the Driver" in the file C:\Cypress\Cypress Suite USB 3.4.4\Driver\CyUSB.pdf

In the step:

"Navigate to the directory containing CYUSB.SYS (Directory Name for various Operating System and platform: wlh(windows Vista, windows 7) and select x86(32-bit OS) or x64(64-bit OS)) based on the platform you want to install driver on.- Open- Ok"

It Shows me a message (I attached you a Printf Screen). "The specified folder not contain any compatible software controller for the device. If it contains a driver, verify that it is design to work with Windows OS 32 bits."

I tried with a Windows OS 64 bits too and the result is the same message.

Can you help me please?

Hi Prajith,

I was able to solve the problem of driver in windows 32-bit OS, when I receive your answer, I had donwload other Cypress .exe and I solved the problem. Now I need the cycfx2dev.cpp and cycfx2dev.h, files that contains the source usb comunications for my Cypress CY7C67300-100AXI.

Thank you for your help :D
