Hello!
I used the slave fifo mode to transfer data from 68013A to cpld, and used the BeginDataXfer function. While I fill the buffer with {22 2A 0B 01 01 ... 01}(total 1024bytes and EP2 is 512bytes double buffer), the fd[15:0] bus will be come {22 2A 22 2A 22 2A ... 22 2A 01 01 01 01 ... 01}(512 words 22 2A and 512 words 01 01)? Why is it, does the BeginDataXfer function can only transfer the first word and copy it 512 times inside? Has any know it?
Show LessCY7C68013A is used for I2C communication on my board, the maximum I2C requency is 400kHz in the datasheet, I wonder whether CY7C68013A can support 1MHz I2C and how to realize? thanks.

I used cy7c68013a to develope my product, and enabled its' CyScript feature to Execute a script at start-up, and i modify my driver's inf file according to the Modifying CyUSB3.INF chapter of CyUsb3.pdf:
MyDevice.EXECSCRIPT="\systemroot\system32\MyDevice\MyDevice.spt"
the sentence above is the last line of the inf file, it defined the spt file path to excute when start-up, I wonder how to modify the path to my user's path?
I have tried to modify the path by edit the key value of DriverEXESCRIPT in regedit, such as: C:\MyDevice\Mydevice.spt or
\userprofile\MyDevice\MyDevice.spt, but all failed. only when I used the systemroot variable, the spt file excuted when start-up (I have already copy the spt file to the path defined in regedit ).
so, how to modify the path as I want?
thank you!
Show LessHi~
when I used cy68013a in my product ,i modifed the CYUSB3.inf file used my own PID and VID, i used two PIDs to enable the device to execute a script file when start-up, then I try to sign the driver, and the below error occured:
"MyDeviceLoad.spt in [MyDeviceLoad.file.ext] is missing from [SourceDisksFiles] section in \MyDevice.inf; driver may not sign correctly until this resolved;"
So i modified MyDevice.inf file as below:
[SourceDiskFiles]
MyDevice.sys = 1
MyDeviceLoad.spt = 1
Then i signed my driver suceesfully.
I wonder when I changed the SPT file in my driver, will the sign became invalid?

I used cy7c68013a on my board. I modifed the CYUSB3.inf file used my own PID and VID, i used two PIDs to enable the device to execute a script file when start-up, and resigned the driver, the driver was test passed in winxp and win7,I installed the driver in WIN8, but when I plug in the 68013 device , I saw "unknown usb device (port reset failed)" in Device Manager.
Please tell me how to solve this problem, thank you!

Show LessGood afternoon all,
Can anyone please tell me how to load .iic file into the EEPROM which is used in xilinx platform cable usb ii?
We tried for loading sample .iic file into EEPROM using control center but the cypress device not detected by this application.
There is any other method to load program into EEPROM?
Show LessHi ~
It is ok that CY68013A is connected to Win7/XP . When CY68013A is connected to Win8, Device Manager on win8 doesn't show up anything. But it showed up unknowd device when CY68013A ->USB Hub->PC.
Pls let me know how to solve the question. Thanks you~

Show LessGood morning all,
Why the cypress (cy7c68013A - 56/100/128) which is used in xilinx platform cable usb/usb ii is detected by cypress control center software?
In order to detect this in control center what we should do?
