You might need to click the write config now button if you're not using an Arduino Mega which comes with the bootloader and config pre-written. Hopefully that will solve things for you.

The Write config on download really only applies to PIC devices.

I am using arduino mega 2560 board.
microchip studio everything works correctly

Hello.
As you are using the Arduino Mega 2560 board, just select Build>Project options.
Right-click on any target and select search.
Enter mega 2560 for the search term.
Alternatively, you can just select the Mega250 from the Arduino range of devices:

There will be no need to change the configuration settings as everything is preset.
Flowcode will program the Arduino board directly via USB lead.
No external programmer is required.
You stated at the start of your post:

today switched to atmega 2560

People will assume that you are using a discrete microcontroller rather than an Arduino Mega 2560 board, which is why you are facing issues.

well, why blink works through microchip studio, but FC9 does not work ???

martin i did everything you said, but the board still doesn't work. now again checked through microchip studio everything is working correctly

Have you overridden the bootloader by using microchip studio?
If you have you will need to reinstall the bootloader.
Arduinos are designed to be programmed via USB and not via microchip studio.

this one through the isp port I upload the firmware hex file

If I was you I would restore the bootloader and then only program via the USB connector and not via ISP.
This might help?
