Apparently the necessary driver to use the serial configuration utility is not supported under ARM Windows 11.
Are there any plans to fix this?
Show LessHi,
is it possible to disable detection of low bus voltage in FX2/CY7C68013A?. bus voltage ,VBUS , could go low due to limited non-damaging current spikes causing FX2 to react.
I am trying to install the CYUSB3 driver for the two CY7C65215 devices (USB-Serial (Dual Channel) Vendor 1 and Vendor 2) on a Windows 7 32-bit machine. I have tried to install both version 1.2.3.14 and 1.2.3.20, with the same error on both devices.
I try to update the driver software and choose the folder that contains the verdor_driver for win7 x86. Inside there are the following files: cyusb3.cat, cyusb3.inf, cyusb3.pdb, cyusb3.sys, and WdfCoinstaller01011.dll.
At the end of the installation I get the error (image attached) and the driver is not installed: "The service cannot be started, either because it is disabled or because it has no enabled devices associated with it."
The problem seems to be when it tries to create the service and cannot create it. But I don't know how to solve it.
What should I do to allow me to install the driver?
Show LessHello,
I am getting different Unique Id for each FX2 controller if REVID register value is 1 but if REVID register value is 4 than I am getting 0 as unique id for each FX2 controller, which is not unique. Why Unique ID is NOT unique for REVID:4 FX2 controller?
Show LessHello Cypress,
Could you please advise how I can identify SBC0/SBC1 of cy7c65216D if both of them are set as I2C?
I am using linux C++ cyusbserial API and want to control 12 GPIOs, do I need to grab both handles of SBC0 and SBC1?
Thanks!

Hello
AN15456-Guide to a Successful EZ-USB® FX 2LP ™ Hardware Design for 3.3 testing below
They are thinking of checking the operation on the board equipped with FX2LP according to the following test items, but could you please tell me the detailed test procedure for each test item?
3.3 Testing
Any USB reset circuit should be thoroughly tested. The following tests are recommended:
▪ Cold power up, plugged into USB
▪ Cold power up, unplugged from USB
Q1) There is a Cold power up in the state at the time of the above test, but please tell me specifically what kind of state it should be before plugged and unplugged.is it ok to think that it mean that only the FX2LP board is powered off before plugged/unplugged?
Q2) Also, please tell me specifically what to check after plugged and unplugged.
▪ Hibernate / resume, plugged into USB
Q3) Please tell me the specific test procedure for the above.
▪ Power cycle, plugged into USB
Q4) Please tell me the details about Power cycle. Also, please tell me the specific test procedure above.
Best Regards

I'm in need to configure CY7C65215A's from Linux. Is the a source package to do so still available?
Show LessHi,
in order to test something I use the CY7C68013A default settings with the built in alt interface 1.
Now I want to also use entpoint 2 as an input just as i do with endpoint 6.
I changed the address on the FIFOADDR pins and used a minimum firmware to just set the EP2CFG and EP2FIFOCFG to the according values (just the same values as EP6CFG and EP6FIFOCFG).
Unfortunately this does not word.
The transfer requests return empty immediately. If I try the same with endpoint 8 (although not addressing endpoint 8 with the FIFOADDR pins), it seems at least to wait for data.
I suspect that the transfer request fails because endpoint 2 is listed as OUT in the interface descriptors even when I configured the above CFG bytes for IN.
I assume I would have to modify the interface descriptor.
How can I modify this quick and dirty?
Can this be done without having to load a full blown firmware into the chip?

Hi,
I was able to use CyUsb.dll in C# project and successfully communicate with FX2LP device.
I would like to know the steps to communicate with FX2LP device using Python.
This communication is required for some test automations.
I found a similar question asked in below thread.

Thanks.
Show LessOur charger product is using the Cypress USB-Serial communication module to connect charger to PC for communication. We used the Cypress drivers and added USB PID/VID info into the drivers files in order for PC to recognize our chargers.
We are facing intermittent PC getting Blue Screen of Death (BSOD) when disconnecting USB cable from PC. The issue happened especially if the charger is connecting through a USB hub (Belkin).
Please advise any solution to solve the issue?
My PC is running on Windows 10 Professional.
