1. Re: How place big size array in flash memory?
I know that the keyword PROGMEM is used for the AVR GCC compiler, in example.
For FX3 I did not find this keyword
Tell me how to do it right?

Hi,
Are you trying to write to the Flash?
What is the interface of the Flash device?
We do have an example which writes to the Flash over SPI. You can refer to the following example for the same:
C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\serialif_examples\cyfxusbspidmamode
In this vendor commands are sent to make the Flash writes.
Please mention if this is not your requirement.
Regards,
Hemanth

Yes.
I understand, that FX3 use a ram vevory.
I want asked:
How I can replace array definition to code space from data space?
Or change linker settings (for more data space memory and less code space memory) ?

When you just want to define an array in flash use a definition as
const char YourArray[5] = {0,1,2,3,4};

As I think, it still leads to overwriting the array from program memory to data memory.
And it turns out double copying.
Is this not so?
