Hello all!
I need to make composite device (Virtual COM-port + SyncSlaveFifo interfaces) based on CYUSB3014 chip.
Now I have two projects which are work separately. What can I read about composite project? What recommendations or application notes from Cypress or other can I read?
Thanks in advance for any response!
Regards,
Evgeniy

Hello Evgeniy,
What recommendations or application notes from Cypress or other can I read?
>> Please refer to the application note AN75779 from the link given below:
In this application note FX3 is implemented as composite devices two UVC interfaces and one vendor interface.
Please refer to the descriptor file and follow the similar procedure to combine (COM port + SyncSlaveFIFO) descriptors in the descriptor file.
Thanks,
Krishna.

The newer SDK(1.3.3) uses the newer version of the GCC (version 4.8.1).
Change the Linker settings from 4.5.2 to 4.8.1. It will work.

I used arm-none-eabi-gcc (default). The files "arm-none-eabi-gcc-4.8.1.exe" and "arm-none-eabi-gcc.exe" are equal in SDK directory.
When I use 'arm-none-eabi-gcc' or 'arm-none-eabi-gcc-4.8.1' I see the same error:
"make: *** [cyfxuvc.elf] Error 1 AN75779_USBVideoClass C/C++ Problem".
When I use arm-none-eabi-gcc-4.5.2, I see different error:
"make: *** [camera_ptzcontrol.o] Error 1 AN75779_USBVideoClass C/C++ Problem"
What else?
