USB low-full-high speed peripherals Forum Discussions

Hi!

I am trying to run the Windows based USB-Serial Configuration Utility. Unfortunately my bord is not found, and I can't find the device on the USB bus.

There are 5 LEDs that seem to flicker at a high frequency on the board. No steady light.
What could be the issue?

I need to make a new configuration file for our factory.
We are programming the devices during production using Linux.

Perhaps there is another way to make a CY7C65215 configuration file without the use of the development board? 

Best regards,
Magnus 

How should I develop a Mass Storage device using EZ-USB FX2LP CY7C68013A, I can't find the documentation that allows to do them on FX2LP, please help me, thanks

Hello Infineon!

I've implemented a FIDO CTAP 2.1 interface on an FX3s but I am getting very strange behaviour with it... I've posted in the FIDO community google group but I don't think I'll get a response there... Any thoughts/ideas would be most appreciated!

To summarize:

1. Driver and report descriptors work as expected
2. HID Communication works

The wierdness:
Situation 1 (working situation)
1. Load up a test page for FIDO (Chrome browser, webauthn.io or other tool, all have same behaviour)
2. Start a FIDO registration process, browser says "insert FIDO device"
3. Program FX3s with FIDO firmware, it registers and handles INIT and GETINFO steps correctly, and sends registration info

Situation 2 (not working situation)
1. Program FX3s with FIDO firmware
2. Load up test page
3. Start FIDO registration, gets stuck in a loop performing INIT and GETINFO until "device fail" message

The part that is really confusing me is during INIT stage, the FX3s must send a new CID value, which the webpage/host must use for future responses, which it DOES use for the getinfo request... This confirms that FX3s -> FIDO HID -> browser and back communication is working successfully in situation 2.....

Is this potentially an issue with chromes implementation of FIDO HID? Is there a way I can "trick" the host with the FX3s to do a reset on a specific USB interface? I do not want to disconnect USB via CyU3PConnectState since it is a composite device and other interfaces may be doing something.

I should also point out there's shouldn't be any real difference in timing between messages sent and received (approx 10~50ms), nor is the content of the replies different. I will be investigating this with wireshark shortly but I am doubtful that a message timeout is the problem since the host should be sending an error if there is one as well.

Regards!

Edit: This only happens on USB3, works as expected on USB2 (Both scenario 1 and 2 work USB2), further edit, responses are always 64 byte in size which is the buffer size so there should be no issues with set wrap up (I think)

Hi, I'm new to Fx2LP
I've been having this problem for days, I need help from everyone.
I have FX3SDKSetup_1.3.4 and sdcc-4.1.0-x64-setup installed.
I'm using 2 methods to build my program and facing a problem:
i) For method 1, download the project from github (https://github.com/matthiasbock/fx2lp-blinky) and add it to the EZ USB Suite as shown below:

The result was a .hex file, but loading it into FX2LP it didn't work.
The hex file when built using this method can be converted to .iic with hex2bix.

ii) With method 2, I used the available example of EZ USB Suite, the way to create is as shown below:

In fw.c, I modified main() to look like this:

__sfr __at (0xB2) OEA ;
__sfr __at (0x80) IOA ;

void main(void)
{
OEA=0x03; // port A as output
IOA = 0x00; // All leds ON
}

The result was a .hex file, loading into FX2LP worked, the light blinked.
However by this method I can't convert to iic, I get the error:
hex2bix -i -c 0x00 -f 0xC2 -o projectName.iic projectName.hex
Intel Hex file to EZ-USB Binary file conversion utility

Error: Input image too big for output file size. Addr = 0xe000, len = 0x20.

I don't know where the error lies, if anyone can give me a perfect sample project, thanks.

Hello,

I would like to know the standard value of VIL undershoot in CY7C65213-32LTXI.

In the datasheet, I found a description of VCCIO+0.2V as the standard value of overshoot for VIH,

but I could not find a description of the standard value of undershoot for VIL.

Regards.
