Arduino STK500v2 not working

Hi,
I try to program Arduino mega2560 with Arduino STK500v2 programmer. First, I write bootloader on ATmega2560 (stk500boot_v2_mega2560.hex) with external programmer USBASP - successfully.

Then I try to upload any .hex with Arduino STK500v2 programmer. I just successfully identify chip. When I click program icon, BASCOM does not respond.
My ArduinoMega2560 have mega8u2 communication chip.

Why programmer doesn't work?

(BASCOM-AVR version : 2.0.8.1 )

hello
the Arduino 2560 and some clone work well without any bootloader please try to store the genuine bootloader from Arduino with the arduino IDE/tools and the last item french it is "réparer la séquence d’initialisation"
then follow that https://www.mcselec.com/index2.php?option=com_forum&Itemid=59&page=viewtopic&t=12472

Hope you save it

Thanks for the reply. Of course, if it works in the Arduino IDE, then it should work in BASCOM as well.
In the past, I wrote incorrect fuse bits with an external programmer, so an error was reported. I have now fixed and it works with the following fuse bits:

-U lfuse: w: 0xff: m -U hfuse: w: 0xd8: m -U efuse: w: 0xfd: m
