Hello guys, I’ve created my Mega2560 standalone board then now im going to test my board but it have some error.
- first im going to bootloader thought SPI port. i’ve watch many guidance on internet. I usb arduino Uno as programmer but when i burn bootloader i got this error "
avrdude: Expected signature for ATMEGA2560 is 1E 98 01
Double check chip, or use -F to override this check." then i found some people use -f command to ignore the error check. but i dont think it’s good idea so then i use USB TTL
- Next use usb TTL to program the my board. the wiring is
then i go to bink sample to blink LED 13 on megaboard so i got new error
“An error occurred while uploading the sketch
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout”
im certainly that every thing parametter on arduino ide is correct. in 1) part, the first i updated the arduino isp to my uno, with the programmer is AVR MKII then i choosen the mega2560 board & programmer is Arduino as isp.
In 2)part i selected the board is mega2560 board. i attached the Schematic file below, pls help meee
