Hello,

CY4500 is avaliable to measure current or voltage of USB 3.0 Device which not applyed USB PD controller??

Hello every. Could somebody give me some advice?

I have an android device and a Cypress device. I want to connect them. And transfer data between them. But I don't know how.

Do we have driver for Android? Or do we have any solution?

I can transfer data between Windows system and cypress device and transfer data between Linux system and Cypress Device.

Thank you in advance.

hello,

         I am working on fx3s to fetch data from fpga to host Pc. while doing this i want to fetch some data like firmware version and hardware version stored in memory from fx3 after sending some data to fx3 from pc as command . My planning is use to send some fixed  data from host to fx3 after sending that data i want check  that data if condition satisfied i want send that data to host pc without effecting the streaming end point  already i am using 3 endpoints one out and two in end points .i want one more in end point and that should send firmware and hardware version to pc after sending some command to fx3  i channged the discrytor and all but not working . can any any one explain me how this problem can be solved i have attached the slavefiffosync code  .

Hello,

sorry but I have to create a new discussion since my previous post (USB-IF Link Layer Test failed ) has been prematurely locked...

I tried to compile my firmware with SDK update 1.3.4 and, in fact, the fail TD.7.17 is gone... but TD.7.9, TD.7.11, TD.7.26 remains. All those fails are related to the new timings used and the Test Equipment (LeCroy M310P / Version: 3.60 Build 780) that USB org. now force to use with no alternative with Ellisys... What can I do now? The waiver ended Nov. 2018 and the device cannot be currently certified...

Moreover, with the update, reappeared a bug that was fixed by you a year ago (MyCase 00396780).

Please Cypress guys, can you contact me privately? I've some reserved data to share... and this matter begins to be quite urgent...

Thanks a lot for your support,

Dax

Hi,

I've added below led test function to cyfxssrammaster.c.

static void

my_led (int loop, int time)

{

    for (int a = 0; a < loop; a = a + 1)

    {

    CyU3PGpioSetValue (LED_GPIO, CyFalse);      /* Turn LED-ON */

        CyU3PThreadSleep (time);             /* ON-time */

        CyU3PGpioSetValue (LED_GPIO, CyTrue);       /* Turn LED-OFF */

        CyU3PThreadSleep (time);            /* OFF-time */

    }

}

After firmware is loaded, I can see LED is blinking. Basically proved LED test code and HW are good.

But if I add my_led to SRAM_READ_COMMAND, led is not blinking.

This indicates SRAM_READ_COMMAND is never run.

My question is how to make the firmware run SRAM_READ_COMMAND?

Hello,

I will develop board like below contents.

FPGA read data on external memory and transmit the data to FX3. And then, PC read the USB data.

So, I want to check USB data from FX3 to PC.

Hi,

I have checked the following discussion below for similar issue. But this does not solve my problem.

https://community.cypress.com/thread/34622?start=0&tstart=0.​

In PC device manager, the device error code is 10.

I try to use EZ USB Suite and give default configuration, after download the build image into CX3 RDK,

PC device manager still show me this error.

What should I do in order to let PC can recognize this UVC camera on CX3 RDK?

Attached file is the project I used to test this issue.

Thanks

Angus
