USB low-full-high speed peripherals Forum Discussions
Dear Support,
in one of our design, we forgot to connect vbuspopwer to the upstream power bus and let it float. seems it works fine most of the time. but we do once a while finding the device not identified by the PC. is these two observations have a connection?
Appreciate your help.
Thanks,
David Sun
Show LessI am Using CY7C68013A for USB interface and transfer data from FPGA to PC of Bulkloop_VSC C#. at starting the device detecting (photo1) but after i Download the HEX file the device detaching but now it is showing as unknown device (photo3) as shown in figures. anyone has idea of solving the problem share with me. The Hex file is generated in Keil for slave FIFO operation. anyone find any mistake in slave.c file please inform me. the pins that i used are according to my selection.

is it necessary to change the printed circuit, to make some programmation.... or is it pin to pin compatible?

Show Lesshi CYPRESS:
When i use cypress CY8C68013A to do myself tool, when i install the kit, it show Cypress FX2LP No EEPROM Device? in my sch , the iic connct to the at24c02 and sch has been attached , when i use USB Console it show the erro, so if the at24co2 has issue or other issue ?

Have CY7C63813-SXC tray Package Carrier part# for M/P?

We use openocd "adaper_khz" to set cy7c65215's jtag clock speed. But the command takes no effect, though openocd doesn't report errors. Measuring the jtag clock with oscilloscope, it is always 450khz. Can we change it?
Thanks.
Show LessHello,
I think that Windows 10 Driver for CY7C65213 (USB-UART LP Bridge Controlle) can be downloaded as follows.
http://www.cypress.com/documentation/software-and-drivers/ez-usb-fx3-software-development-kit
Is this EZ-USB FX3 SDK 1.3.4 for Windows driver available on ’Windows 10 Enterprise 2019 LTSC ' ?
Or need a new driver ?
Please provide a driver for Windows 10 Enterprise 2019 LTSC if it exists?
Best regards,

Show LessWhen FX2 device with FX3 SDK , .hex file is generated but iic file is not generated.
I can write program to RAM but can't write to EEPROM because there is no iic file.
Files built with keil can be converted to iic files with HEX2.bix.
I get an error when I try to convert data built with EZ USB Suite.
PS C:\Tools\Cypress> .\Hex2bix.exe -I TestProject.hex Intel Hex file to EZ-USB Binary file conversion utility Copyright (c) 1997-2005, Cypress Semiconductor Inc.
Error: Input image too big for output file size. Addr = 0xe000, len = 0x20.
PS C:\Tools\Cypress>
Size of two files is almost equal.
Please tell me how to generate iic file with FX3 SDK.

hi Cypress:
在使用CY8C68013A的问题,上位机需要发送512Byte 或者其整数倍的数据才能接受到; 如果发小于512Byte 的数据
则无法接受到, USB的相关协议中应该是需要发送相关操作指令才可以实现非512byte 接受, 客户需要知道怎么进行操作? 是否有相关的
建议; TKS;
