Hi, Infineon:

We're making a USB dongle using CY7C65215.
In the USB host, we have an app reading from USB serial TTY, recently we upgrade libusb from 1.0.21 to 1.0.22.

If we unplug and plug the USB dongle back, the app won't be able to detect the device. CyGetDeviceInfoVidPid() return CY_ERROR_DEVICE_NOT_FOUND.

If I kill this app and restart it, it can open the USB dongle, seems CyUSBSerial_SDK_Linux doesn't cleanup libusb properly.

Thanks

I need to reconstruct one of these; is it possible to supply either a schematic or the corresponding programming data for the IC involved?

Just to explain, I need the CY3083-02 card for the CY7C64013-SC.

Many thanks

cyusb3014,sample: firmware\serialif_examples\cyfxusbi2cregmode

​I send vendor command (USB control center) but it shows:

CONTROL OUT transfer failed with Error Code:997.

How to avoid this?

Thanks.

Hello,

In the Device Configuration Utility (Windows only) of USB-Serial Bridge IC, there is a parameter "VBUS Voltage is 3.3 V", and it is explained to check the checkbox when supplying 3.3 V from VBUS to CY65211.

Is it possible to use VBUS 3.3V in the same way in Linux system?
If so, how should I configure it?
As you know, there is no Device Configuration Utility provided for Linux.

Thanks.

Hello I am using FX2lp and i referred to this article and followed the steps in the article Usage of Serial Ports 0 and 1 on FX2LP, implementi... - Infineon Developer Community
However, I use tera term instead of Hyperterminal but i am not able to see anything on the tera term. I exactly follow the steps but most of the times bulk out and in fails

hello, we've managed to successfully get an arm64. version of the drivers working for (only) a usb peripheral that we use and have verified that it works in test signing mode. the source code is intact with some amendments made to the .inf file. could you please guide me on how i can get my driver signed so that we can have it circulated internally within our team (and externally back to you if necessary) ? 

HI,everyone

      I am currently programming SPI FLASH in FX3 Control Center (W25Q32JVSSIQ), but have been stuck in programing of spi flash in progress... ; When I used the logic analyzer to capture data analysis, I found that when the control center started FLASH programming, 3014 first issued the command 0x06, then 0XD8000000, and then issued the command 0x05 to query, FLASH reply 0x03(busy flag); About 150ms later, the FLASH chip returned to 0x02, but 3014 still sent 0x05 without further instruction. Could you please give me some advice

HI，support！

    We want the CY7C65211 to be able to change the pid to 0x40 under Linux, making the chip work in SPI mode. What should we do? Update command code through code? Or a configuration tool under Linux? (Can you provide us with command code or configuration tools under Linux? Thank you.)

Hello,

Anyone out there having experience of using  the CY7C65215 as USB to I2C bridge for communication with an SSD1306 or SSD1308 OLED display?

I have not yet managed to test this myself, and I am wondering if there are any technical or API limitations preventing this combination from working?

Thanks!

Best regards,
Magnus
