USB Superspeed Peripherals

Hello!

I want to use Slave FIFO and UART within single FX3 firmware, so I've merged two well-known Cypress examples, combine descriptors, so on. I use 0x00F1 as product ID.

Driver setup is very tricky:

1) initially my board was displayed as a Composite USB Device in the Device Dispatcher

2) I've modified cyusb3.inf by adding string

%VID_04B4&PID_00F1.DeviceDesc%=CyUsb3, USB\VID_04B4&PID_00F1&MI_00

I saw StreamerExample in Device Dispatcher after that update, but there was no COM port yet.

3) I've modified CypressSerial.inf by adding string

%CypressSerial% = CypressSerial.NTamd64,Ports\VID_04B4&PID_00F1&MI_01

I got two COM ports with that update.

I did not check UART yet, but Slave FIFO works good.

So, my questions:

1) is the procedure, described above, normal/usual with FX3  or not? Are there any less tricky ways to reach the same?

2) why do two COM ports appear, but not one? Are both of them functional or not? If no, which of them should I use?

Many thanks!

With regards,

Maksim

Hello Maksim,

I had not added the CDC functionality in firmware that i had attached in my previous response. I had just changed the descriptor file. For CDC functionality .c file need to be changed accordingly to handle the CDC

You shouldn't get two Com Ports when FX3 is programmed: One should be as Cypress Fx3 Streamer Device and one Serial Com Port. Please use fresh driver files before testing and not the one that you modified.

I have tested this firmware on both High speed and Super speed

These are the steps you need to follow:

- Please load the attached firmware (with CDC functionality added). I have combined usbuart sdk example with slavefifosync firmware.

the #define cdc enables switching between slavefifo and slavefifo + cdc

- Check the Device manager - uninstall the device (with yellow mark)

- Program the FX3 again  - FX3 will be seen under other devices - and a serial port will be seen under Port (COM & LPT)

- You need to bind FX3 with Cyusb3 driver  (choose Cypress Fx3 Streamer Device)  and serial port with Cypressserial driver

- You can see FX3 as Cypress Fx3 Streamer Device and one Serial Com Port

-Now as per the functionality of usbuart SDK example and Slavefifo:

  -The fx3 will have functionality of Slavefifo

  - The second functionality will be as serial com port

The UsbUart example is have channel from usb to uart and uart to usb. So connect the uart pins or use int integrated debugger (if using CyUSB3Kit-003 explorer kit).

- Open two windows of teraterm : one with FX3 as CDC and other with the uart lines.

- Try transferring data.

Please find the attached results of my tests

Rashi

Hello Maksim,

You don't need to chnage the .inf files. If you change the .inf files the signature would be lost. You can only do this for testing purpose.

can you try without changing the PID of the default Slavefifo firmware (in descriptor) and just add CDC as an interface. Then check the enumeration. Both the interface would be shown (i.e. CDC and FX3) . You would need to bind the driver manually to the devices.

Please share the snippet of the device manager (without making changes to .inf files)

Hello, Rashi!

I have modified descriptors already, for example:

const uint8_t CyFxUSB30DeviceDscr[] __attribute__ ((aligned (32))) =

{

    0x12,                           /* Descriptor size */

    CY_U3P_USB_DEVICE_DESCR,        /* Device descriptor type */

    0x10,0x03,                      /* USB 3.1 */

    0xEF,                           /* Device class */

    0x02,                           /* Device sub-class */

    0x01,                           /* Device protocol */

    0x40,                           /* Maxpacket size for EP0 */

    0xB4,0x04,                      /* Vendor ID */

    0xF1,0x00,                      /* Product ID - Using the Cypress StreamerExample for driver binding */

    0x00,0x00,                      /* Device release number */

    0x01,                           /* Manufacture string index */

    0x02,                           /* Product string index */

    0x00,                           /* Serial number string index */

    0x01                            /* Number of configurations */

};

but as I already wrote, I see only Composite USB Device in the dispatcher.

So, I can't split it to StreamerExample and COM Port without modifying .inf files.

Entire cyfxslfifousbdscr.c is attached.

Thank you!

With regards,

Maksim

Hello Maksim,

Please try replacing the descriptor file that i have attached to you firmware and check the enumeration.

Please let me know the results.

Hello, Rashi!

I see SreamerExample Device after the descriptor update from you, but there are no Composite Device and COM Port, while UART is a part of my design and I need to use it.

I suppose, the current .inf files (both for Streamer and CDC) cannot be used for Slave FIFO + UART firmware, because there is no support for MI_00 and MI_01 configurations.

Am I right?

Many thanks!

Hello Maksim,

I checked the firmware with this descriptor file (please find the attachment)

By changing the PID the signature might have lost. Can you please try by getting fresh .inf file

1) I have completely reinstalled SDK and Serial Driver pack, than delete my device from the system using dispatcher

2) I rebuilt the project using your descriptor file.

3) I installed original FX3 drivers from SDK when my device was found.

4) I still see only the StreamerExample and I got no request to install Serial Port Drivers, please check picture (COM1 is a built-in one).

5) Your descriptor file has not the same endpoints as my projects uses. Is it a possible reason?

Hello Maksim,

That doesn't seem a problem.

I have attached the default firmware with modified descriptor file. It already contains .img . Please check with this.

Rashi, I just loaded .img directly through Cypress Control Center and I got the same result - no COM Port.

By the way - why do you expect COM Port to be found, if there is no string in .inf, saying there is a composite device with COM Port?

Windows sees StreamerExample device, installs it and successfully finishes, please check setupapi.dev.log part below:

Hello Maksim,

- Please try programming the attached firmware.This will show Cypress Fx3 USB Streamer Device with an warning (yellow mark). You need to uninstall the device with checking the option for Delete the Driver software for this Device.

- Program the FX3 again with the same firmware.

        - Now you might see FX3 under other devices.

        - And one COM Port

- Now you need to manually bind the cyusb3 driver to the FX3. The COM Port might be binded to Windows driver.Bind the COM Port to Cypressserial driver.

- If you don't want to bind the drivers manually, you would need to change .inf file. On doing so the signature would be lost and you would need to get it signed again. You can refer to these thread CyUSB3 : Cypress VID/PID allowed in third party INF ?   Driver Resell - CyUSB3.sys

Please let me know the results.

Rashi

Rashi,

it works as you described and creates 2 COM ports after manual binding to Cypress driver, but there is no actual data transfer through them: the first one cannot be opened, while the second one opens, but there is no signal on FX3 UART output when I'm trying to send something.

By the way, I get two ports also when I use modified .inf - one is unusable, but another one works great.

So, some issue still exists.

Thank you!

With regards,

Maksim

Hello Maksim,

I had not added the CDC functionality in firmware that i had attached in my previous response. I had just changed the descriptor file. For CDC functionality .c file need to be changed accordingly to handle the CDC

You shouldn't get two Com Ports when FX3 is programmed: One should be as Cypress Fx3 Streamer Device and one Serial Com Port. Please use fresh driver files before testing and not the one that you modified.

I have tested this firmware on both High speed and Super speed

These are the steps you need to follow:

- Please load the attached firmware (with CDC functionality added). I have combined usbuart sdk example with slavefifosync firmware.

the #define cdc enables switching between slavefifo and slavefifo + cdc

- Check the Device manager - uninstall the device (with yellow mark)

- Program the FX3 again  - FX3 will be seen under other devices - and a serial port will be seen under Port (COM & LPT)

- You need to bind FX3 with Cyusb3 driver  (choose Cypress Fx3 Streamer Device)  and serial port with Cypressserial driver

- You can see FX3 as Cypress Fx3 Streamer Device and one Serial Com Port

-Now as per the functionality of usbuart SDK example and Slavefifo:

  -The fx3 will have functionality of Slavefifo

  - The second functionality will be as serial com port

The UsbUart example is have channel from usb to uart and uart to usb. So connect the uart pins or use int integrated debugger (if using CyUSB3Kit-003 explorer kit).

- Open two windows of teraterm : one with FX3 as CDC and other with the uart lines.

- Try transferring data.

Please find the attached results of my tests

Rashi

Rashi,

many thanks for your help! Now it works good.

Manual binding is better than .inf modification.

By the way, are there any method to change device name in the Dispatcher without .inf modifying/signature loss?

Thanks again!

Maksim

Hello Maksim,

You cannot change VID or the device name without doing changes in .inf file.
