Hi,

We are working on a 2-port USB hub using CY7C65620 IC. We have a question regarding the EEPROM. If we don't add EEPROM in our design and just connect the SPI_SD pin to ground, will our hub work with windows or Linux system normally? 

Thanks,

Hi, Infineon:

Our board has a CY7C65215-32LTXI connected to BCM47768 through UART (GPIO pins 3,4,5,8)

Hi,

We are validating UART vendor mode flow control of CY7C65215 via CYUSB236 EVK with Cypress Linux SDK. As shown in attached test report, we found CTS of CY7C65215 is active HIGH which doesn't comply with RS/EIA-232 standard that defines RTS,CTS as active low.

The non-standard CTS behavior of CY7C65215 causing it failing to receive data from other standard active low UART devices as RTS/CTS flow control is enabled.

Could you help provide methods for configuring RTS/CTS of CY7C65215 as active low ?

Best Regards,

Justy Huang

We are using USB HUB PN# CYUSB3324-88LTXC on the board but  in case if we Assemble the PN# CYUSB3328-88LTXC on the same FP (pl. help to re-validate whether its FP compatible), then what other HW or FW changes would be needed to operate the HUB functionalities same as currently used PN# CYUSB3324-88LTXC?

I’m using the EZ USB FX2LP Discovery Kit with Windows 10.  I found the set of drivers in this forum, and  did have the driver working once.  But now, when I connect to the board, a window comes up that states “USB Device Not Recognized”.   In Device Manager under “Universal Serial Bus controllers” it shows up as “Cypress FX2LP No EEPROM Device” but has the triangle exclamation point symbol.  Under Device status it shows “This device cannot start. (Code 10)  A request for the USB device descriptor failed.”

I tried to update the driver again but still get the same error.  Any suggestions?

I am creating a C++ app to control my USB device. All i need is to link the cyapi.lib from the cpp library folder to my project?. No need for the CyAPI.dll during the run time?.  I read CyAPI.dll is for .NET application development.  There is no need for the CyAPI.dll for the non-managed C++ APPs?. I could not find CyAPI.dll for non-managed C++ in the install directory.

where can I find the latest PDF for programmer's reference.

hi,When I set the CY7C68013A to 16 bit data transmission, I found that 512byte data would be lost every 512byte sent. Why and how to modify it

but it's ok when 8bit data transimission

Hi, Sir,

1. Does CY7C65211A support "I2C - Repeart Start" ?

2. and how to generate the “repeated START” with the CY7C65211A?

could you please provide sample code?
