I'm unable to make UART serial communication with FX3. I tried UartLpRegMode example. When I single stepped through my code with a J-link segger debugger, I realized that rxTxByte is always zero and apiRetStatus is 69. I'm not getting anything on the serial terminal when I set to the baud rate I configured in the program. Tried putting some CyU3PDebugPrint statements, but nothing is getting printed. Even, after configuring the UART. Tried shorting TXD and RXD pins to see any loopback, but no improvements. Even manual values are not getting printed. I'm not sure, whether I'm running properly and testing. Any suggestions would be greatly helpful. Thanks for helping !Show Less
Q1)Regarding the bMax-power, it is described on page 14 of the datasheet, but we are understanding that it is necessary to set the Maximum Power value for each connected "devices"?
If no, please tell me the details.
Q2-1) The default value is described as "32h(100 mA)", but please tell me the reason.
Q2-2)When powering HX2VL with self power, is it possible to change the bMax-power descriptor
information by themselves to FAh(500 mA)?If yes, is it possible to change the bMax-power value of EEPROM directly?
Please tell me the state(CMOS output or Open drain or Hi-Z) of PWR#_I2C_SDA pin(26pin) during the following each operation period?
Case1: During Reset.
Case2:Immedietely after reset cancellation(Initial setting).
Case3:During I2C operation.
Case4:Transition period of I2C operation END to /PWR operation start.
Case5:Immedietely after /PWR operation is started(Initial setting)
Thank you for the response that indicated B7 was a new version of firmware.
The ZIP file you attached is password protected so I can not access the files in it.
Is there a file that explains what the new changes are in B7? If we are going to update firmware we need to know everything that changed.
It looks like the zip file contains firmware and configuration settings. We already use custom EEPROM settings in our product.
The latest on the Cypress web site appears to be B5 so I cannot get it there.
Hello, We have designed a hub based on the CYUSB3314 chip. The hub has failed USB compliance testing because the bcdUSB string returns 3.00 instead of 3.10. I see no way to change that in the configuration EEPROM. Does that mean this chip is now non-compliant for USB 3.1 Gen 1 certification? The USB.org has stopped the use of the USB 3.0 name and only uses USB 3.1 Gen 1 as the official designation. Could this be remedied in an HX3 firmware update?

Is there any tool that can download HX3 configuration data and firmware from Windows command line?
There is a HX3 Blaster Plus tool to download configuration and firmware on HX3, but
customers desire tools that can process batches on the command line programming on factory production lines when they are mass-production.
What about GX3?
Also please provide a tool that can execute the GX3 EEPROM programming tool on the command line if you have one.

I assembled a PCB based on the Schematic:
My scheme in the attachment (1).
I write a standard file 2_port.iic in the EEPROM with the program "Blaster".
The hub is defined as a universal USB hub in the device manager. But connected to the Downstream Ports flash cards are defined as an unknown device!
Help me please
Why the hub does not work correctly?Show Less
Hi , I have a question about the CY7C68013A Chip,it is working in Slave fifo mode.Because of the loosening of the USB interface,PC software disconnects USB connection。Especially,The power supply is open, but the USB line is disconnected,it is not possible to reconnect 2 times and receive data。I want to konw how to reconnect of the CY7C68013A and receive data?Show Less
I tried to search for an answer here but did not get any specific details- Can you please let me know what is the difference between CY7C63743C-SXC and CY7C63743-SXC (without C)?Show Less
