AN75778 UVC Framework porting to CYUSB3012

[Cromagnon]

Hi,

The AN75779 runs properly on the Cypress evaluation board, which uses a CYUSB3014 device. We want to port this application to run on a CYUSB3012 which has only the half of internal memory (256K instead of 512K).

The first try was to change the memory setting in the file: "cyfxtx.c" and also to use the appropriate linker file: "fx3_256k.ld". The result was, that the application complains about a memory allocation error.

QUESTIONS:

1) Is the described way to specify the device restriction regarding memory correct? Is anything missing or does there exist another method to specify the used device?

2) Is it possible to modify the application to work also with less memory? And if yes, what must be changed?

3) There are a lot of functions which are not available as source code. Is it possible to publish those source files?

Kind Regards

Cromagnon
