Topic: AVRdude+YunShield+ArduinoMegaADK (Read 3484 times) previous topic - next topic


I'm using Dragino and Arduino Mega 2560 (Mega ADK actually, but they are almost the same).
I can upload firmware to Arduino Mega through web interface and it works perfectly, so the connection is OK.
But I need to use avrdude (or any other if You can suggest any) to upload a hex file to Arduino from Yun shield.

I rely the following preferences from averdude.conf

  id    = "linuxgpio";
  desc  = "Use the Linux sysfs interface to bitbang GPIO lines";
  type  = "linuxgpio";
# for DS1 board
#  reset = ~18;
# for DS2 board
#  reset = ~7;
# for DS2_B board
  reset = ~20;
  sck   = 18;
 mosi  = 6;
#  mosi = 21;
  miso  = 22;

But maybe GPIO that i specified are wrong? I tried it also for Arduino UNO. And it does not work, Can You help me with this?
I use command
avrdude -c linuxgpio -p atmega2560 -U flash:w:led28.hex -b115200

And receive
avrdude: AVR device not responding
avrdude: initialization failed, rc=-1

I would be very grateful for Your help.

P.S. I also tried the following
 GPIO18 <----> SCK
 GPIO22 <----> MISO
 GPIO21 <----> MOSI
 GPIO20 <----> /RESET
 GPIO23 <----> SS

It didn't work

P.P.S. I also tried to use Arduino UNO
Using the command

avrdude -p atmega328p -c linuxgpio -U flash:w:led28.hex -U efuse:w:0x00:m -U hfuse:w:0xdd:m -U lfuse:w:0xff:m


The averdude command that I wrote above is wrong. Everything was fine with averdude.conf
