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.
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
