Hello, Cypress expert,

I have a question about the EZ-USB FX2. I am using uVision Toolchain C51 compiler/Assembler Kit Version:9.56.0.0.

after compile, it generates a hex file. I run "HEX2BIX -IR -M 16384 -F 0xC2 -O Scan_BD_FW.iic Scan_BD_FW.hex" to convert it to iic format,

this iic file works fine with cyconsole. but if I use the hex file write to microchip 24lc128. the system not work.

so I have to use Cyconsole to load the iic file to this eeprom. and use the eeprom programmer to read the master chip file out. then load this file to the chip.

I don't understand why the Hex file can't be used directly to load the EEprom. is there any trick? do we need to setup some special parameter of the eeprom programmer to make it work.

Thanks,

David Sun

hello ,

           we are using the CDC Class in FX2LP to write data to port we want to set the baud rate more than 921600 when i referred the application note AN58764 maximum baud rate is 115200 . how to increase that baud rate to  around 921600 . if any one has idea please let me know .

thanks regards,

Hi,

I'm using CY7C68013A-56BAXC and I have a problem about heating issue of this device.

Heating occured after device configured.

What makes this device heating?

I think some register of device makes heating.

Please advice me about this heating issue.

Best Regards,

Matthew

Hi ,

      We are using cypress USB products  .when we will connect to PC via USB and checked in Device manager  these devices comes under Universal serial Bus controller category but we want  as imaging Device  because we interfaced with image sensor  i have attached the screenshot  PFA. So  we wanted to change from Universal serial Bus  controller category to imaging Device  .Can any one help me to change ?.

Thanks Regards ,

Hi Cypress,

for production, we need to program the EEPROM 24LC128 for Cy7c68013, it is easier to program the chip with a standalone programmer. but the programmer only loads HEX file.

the HEX file compiled from uvision can't be used for this purpose.

what we can do is use HEX file, convert to iic format, then load to 24lc128 on a developing board. then use the programmer to copy the image to a file. then burn this file to the EEPROM. is there a way to generate a HEX file can be burned in the EEPROM directly.

Thanks,

I  have an application to  transmit 640x480 image sesnor data  over FX2LP  USB 2.0 using UVC through FPGA. I tried  to find the firmware online, but no result.  Then I tried to develop  it myself, but it did not work .Can any one provide it ,thanks

Hello!

I want to implement UVC using FX3 (trying on SuperSpeed Kit). There is no problem with UVC examples from SDK, but I have no luck to modify USBVideoClass example to work with uncompressed frames. I've downloaded specs from USB.org - USB Device Class Specifications and changed format and frame descriptors as described. I've also changed Probe and Commit control structs.

Is there any example of FRAME_UNCOMPRESSED video translation?

v4l2-ctl output:

Dear Technical Support,

as described in the PDF Chapter 3 of the Cypress CyUsb3.sys Programmer's Reference, I would like to start the Driver Resell procedure in order to have a customized driver for my hardware (based on FX2LP Cypress USB) with a dedicated .inf file. in the documentation it is written that I:"need to contact Cypress Technical Support and create a case(https://www.cypress.com/

support) with the below information to initiate the driver resell process.

1. Company details.

2. INF file with your devices VID/PIDs. "

I prepared all this info but which is the right way to contact cypress Techicanl Support and create the "case", is by this community or may I have a direct email contact with a Cypress representative?
