hi... blesings all
after spend time on cloned arduino mega2560 rev3 16au sold without proper bootloader, post here info may help
when pluged first time
the "l" led didn't want blink. (this led blink if bootloader in chip)
and sure,it impossible load sketch on it, using ide 1.6.3
all got "avrdude: stk500v2_receivemessage(): timeout"
ok "l" led don't blink bootloader problem
you can perform loopback test (bridge rx0 & tx0 pin , bridge reset & gnd) sure
then in ide go >tools>monitor serial
write something... if console return text, meens board recognized fonctional computer
now need programm burn bootloader , make arduino mega clone life
the programm below allow burn bootloader on various type of controller , other usefull things
using arduino uno perform transfer
how burn bootloader ?
you need :
an arduino board that work "downloader"
6x female-female , 1x male-female dupont cable (or whatever want)
the bootloader sketch
your board burned
1#
plug 6 cables 6 isp pin of arduino uno 6 isp pin of 2nd board
un pluged 5' pin of arduino uno (this bottom.left) , connect cable pin10 (with male -female , got )
2#
download sketch -> https://github.com/nickgammon/arduino_sketches (thanks him)
3#
open new sketch -> select atmega_board_programmer.ino
in monitor serial -> select 115200 bauld (or have problem of reading)
load sketch
follow instructions
that's all
enjoy
additional comment serial ports :
it seems there differnece beetwin ports name attached board
on windows :
-arduino mega (clone) lauch com*
you need appropriate driver (i use ch341ser that worked perfectly) , add manualy in windows (update driver in configuration panel)
on ubuntu :
-arduino mega 2560 (clone) launch ttyusb* (ttyusb2 me , can find in /dev folder hidden file showed)
put driver folder in arduino directory (i don't know if have did , worked perfectly)
-arduino uno (official) launch ttyacm* (acm0 me)
one love
