Hello,

Does anyone work on EZ USB FX2LP? Basically, I wanted to do FIFO Read and Write transactions. When I loaded the precompiled firmware the board disconnected and connected again which is supposed to do.  But the driver of the FIFO example comes with a yellow mark in the device manager. I search for the driver but didn't find it. As per documentation, the driver installed automatically after loading the firmware but it didn't do. 

When I compile the files again and load the firmware then it does nothing. This means instead of loading the precompiled version of firmware I compile it again in Keil.

Can anyone purposed a solution to this problem?

Please see the attached file for precompiled firmware.

It also has some examples as well as step-by-step instructions.

Kindly go through it once and let me know if you have any queries.

Hi,

Please confirm if before loading the firmware, how did the device enumerate.

What firmware did you program and how did you program?

Regards,

Hi,
I am new to this board. I load the FX2_to_extsyncFIFO example to fx2lp. I load the firmware using the cypress control center.

You can see the video how I load the firmware. And compile same program in keil.
I compile on keil uv2 because I don't have keil uv5 licensed.
