Hello everyone,Last week I received my slim node board designed by m26872 and begun the process of burning the 1Mhz bootloader. I faced some problems for a couple of hours and google helped me to successfully burn it and uploading the sketch.Please correct me if I missed something. Hi there, and thanks for the tutorial. I'm trying this for the first time (the ATmega is going to be used in a slim temp node), and I'm receiving this message you mentioned: avrdude: Yikes!

Invalid device signature.Double check connections and try again, or use -F to overrideYou mention we should try the following: Maybe your chip is configured to run on an external crystal clock. I tested with two values and it succeeded. I used 10Mhz and 20Mhz as I didn't have 16 Mhz.Connect the crystal to pin 9 and 10Note: You won't need the crystal except for the first time as the new bootloader is configured to run on internal 1Mhz or 8Mhz.I don't quite follow what this means? Do I need a 10mhz, 16mhz or 20mhz crystal attached to the breadboard like you show in the video?

If so, is that the only change I would need to make?FYI I'm using an Arduino clone (Buono uno r3, set at 5V). Maybe I need to rephrase the sentenceI meant that any crystal value will work.

I didn't have 16Mhz, but I had the values 10Mhz and 20 Mhz. So I tested with 10 Mhz and I bypassed the error and didn't come again. I wanted to know further whether the crystal value is important or not.

So I got another chip with preloaded arduino bootloader, and tested with 20Mhz. Also I succeeded.

16 May 2019- The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. Open up Device Manager and you should see that the Arduino is not longer recognized as a virtual COM port. Install the “old” drivers manually. Connect the ISP programmer to the nano. Burn the bootloader with Arduino IDE. Remove the ISP programmer and connect again with mini USB.

Thus I assume that you can use any value for this step.I am also using Uno clone and this is the only thing I did regarding this issue. I didn't even add capacitors to the crystal. Just put any value and test. Hello,Could someone help me and give info what I'm doing wrong or have an idea whats happening.I use this tutorial and burn 1Mhz on Atmega328. After that I'm trying to upload sketch with FTDI and test Atmega in two ways:. When I connect power supply 2xAA batteries (new ones).

When I connect power supply 5V from FTDI.When I trying to upload sketch with 2xAA batteries, Atmega comes unresponsive and I get: avrdude: stk500recv: programmer is not respondingavrdude: stk500getsync attempt 10 of 10: not in sync: resp=0xe3When I trying to upload sketch with 5V from FTDI - everything ok, example works (blink or ASCII table example).When sketch is uploaded with 5V and then I try to connect 2xAA bateries - its not working again. When I open serial monitor from arduino IDE I see blank window or few times there was strange character.I checked few times boards.txt file with fuse setting, and there is set ' apm96.bootloader.extendedfuses=0x07' wich means BOD disabled. So it seems should be like that.I was trying to do all steps with different Atmega328 and also trying same steps when I burn 8Mhz bootloader. Got same result.Please give me some shots what I could test else here, becose I'm out of ideas. I'm trying to run My Slim 2AA Battery Node.Thank You! Any help would be very useful. Thank You for reply!

What is the upload speed you are using now? This is defined in the boards.txt file for each board selected.I found that if I burn the bootloader with 5V FTDI, and then try to upload sketches at 3V (with batteries connected), the internal oscillator runs at a slightly different speed.When you use higher upload speeds, this small difference can result in too high error rates.That is why I use 9600 baud to upload sketches for 1MHz mcu's.For 8MHz mcu's I use 38K4 baud, and for 16Mhz I can use 115K on Arduino Uno's, but I tend to use 56K on my 16Mhz nodes.Each time I use the approriate bootloader compiled for that clock speed. Battery connection is good. Battery voltage: 3.25V (when not connected to circuit)I check again all wiring, measure voltage on circuit and its 3.22-3.23V, check voltage directly on chip pins - its same voltage too.Still got 'not sync' when trying to upload sketch.

Interesting that when I have connected battery power and try to upload sketch over FTDI, led conected to D13 blinks and after that I get 'not sync'.Upload speed is: apm96.upload.speed=9600Yes, I use same part in boards.txt file like in screenshot you posted and also like in the given link in tutorial:If I burn bootloader to Atmega328, with battery powered, shoud it might work? Said:For OTA you need to flash the boot loaders that allow this.

The standard boot loaders do not have this ability to OTA update.Ok, but after the new release of mysensors ver 2.0 lib and my wish to update my gw and sensor nodes I would like to add OTA update ability as well for upcoming updates. So does a 1 MHz Bootloader with OTA exist that is compatible to the one from above?. Could OTA easily be added to the above 1MHz Bootloader?. Should i just use the 'ATmega328 internal 8Mhz with MYSBootloader' instead of the above mentioned bootloaders? Help!I semi-followed this thread but also built a shield like this:For the Uno, the ArduinoISP sketch goes fine. After that, I connect the shield and 328p and upload stuff.Since my build has 3.3V regulated power (using PCB My Slim 2AA Battery Node.but I can sneak wires to it easily so no need for batteries), I selected 'Board - Pro Mini' and type '3.3V 8Mhz'. Burn bootloader goes fine, no errors.

Upload sketch using programmer (Arduino as ISP) also uploads fine.When I plug it in (USB FTDI-clone 3.3V selected) and see serial monitor, it remains blank. Nor does the node work when plugged into power.Anybody else try this? The slim node has all caps and resistor connected.EDIT:I used the recommended board download from 8Mhz instructions and bingo, it's working.partly. Have to check radio wiring.Should just follow instructions and not go off on my own. Continuing on.I need help getting my Atmega328P-PU to work.I'm able to burn the bootloader (8MHz on breadboard) and upload sketch ('using programmer').

However when I power the PCB, the sketch doesn't run. I soldered on a LED and uploaded BlinkWithoutDelay, just to verify that it works, but does not. I measured power and all connections. I'm powering with regulated 3.3V.To make things more weird, I connected FTDI to one node and with that connection it works fine. But when powering from pins, nothing (again using regulated 3.3V.

Everything's 100% chineseI checked power at all terminals and the atmega-connections, as well as radio hookup etc. I have all the caps on 'My Slim Node' (4x 0,1yF and 4,7 yF).

I normally get better power thru regulators than with FTDI but I did check that originally.I built two like this, same type of problem. I have Gert Sanders's 'boards' installed. Is there a very basic setup I could try?

I'm having trouble figuring out all the options that are available. All I want is Atmega working like a normal 3.3v/8MHz Arduino.

I always have that nagging feeling.But after MANY iterations, finally success. At least partly.BlinkWithoutDelay works AND mysensors sketch as well (will do more testing.).What made it work, if anyone else struggles with this:-connect uno (to computer-linux), board:uno, upload ArduinoISP, disconnect-add shield to uno and atmega328p-pu to shield, connect to computer, board: '8mhz on breadboard', 'programmer: 'Arduino as ISP', burn bootloader, disconnect-board: Uno, connect as above, 'upload sketch using programmer', disconnect EDIT this last part appears to work but internal clock is all messed up. Bootloader works fine like this.The magic happened after I changed the board back to Uno after burning bootloader. Why is beyond me, but maybe some arduino-ninja can figure it out.

Can someone help me with these questions?I want the Slim Node to function 'like a 3.3/8mhz pro mini' for MySensors home autom applications. So I can upload sketches thru ftdi-pins.

Since I also use Pro Minis, I would not want change the mysensors library (serial baud). if I load the bootloader with a 8mhz crystal on the breadboard, does my barebones Slim node need a crystal too?. If I set serial.begin in the sketch, does it override the MySensors default?

So I could have that for slim node sketches. What kind of nodes would be problematic without crystal use? Repeater?. Is it possible to Uno+breadboard just bootload all atmega328p's and then just solder onto SlimNode and use ftdi for uploading sketches (as I would normally to a Pro Mini)? In other words do I have to rethink the whole thing.EDIT, to help others.

if the bootloader is not set for crystal, it's not needed. yes.? Repeaters work fine. yes.My biggest problem was a capacitor missing between RST and GND when uploading bootloaders. After adding that to my shield, everything works.Now I bootload 1Mhz (battery nodes) and 8Mhz (non-bat) once I get them and then program them with the FTDI when I build the nodes. First of all thanks to all who worked on this tutorial and bootloaders.

TFTP Bootloader for ATmega328P/Atmega2560/Atmega1284P /w support for Wiznet5100, W5200 and W5500This is a beta stage bootloader for Arduino Ethernet board and the regular Arduino with Ethernet Shield.It is based on previous unfinished work by the Arduino developers. The bootloader implements a TFTPserver on the Arduino board and flashing works using any regular TFTP client. The Files and Folders in this RepositoryThe structure of this repository is made to follow the standarts of the Arduino IDE. This way you cansimply copy the folders in your sketchbook and be ready.

hardware: This is where the bootloader resides. java-client: Demo client for the bootloader. Inherited by the initial project. Untested and probably non-functional. libraries: Helper libraries to support functions of the bootloader.

utilities: Various stuff used for development and debuggingDownloading and Installing FilesFirst of all, you need to clone or download the repository. To clone the repository you need to havegit installed, then you can run git clone in adirectory. This way you can later update your local repository by running git pull inside theSEM-Bootloader directory.In case you want to avoid this hassle, you can use the ZIP button at the top of the page to downloadthe latest snapshot of the repository in a zip archive and extract it.After that you have to copy the hardware and libraries folders inside your sketchbook folder.Take extra care during coping not to overwrite any other files. Cyber ghost activation key. Restart the Arduino IDE to load the newboards and libraries. Installing the BootloaderTo burn the bootloader, you will need an ISP(in-system programmer) like AVR-ISP2, USBtinyISP3or you can build a ParallelProgrammer4 or an ArduinoISP5.

The first three programmers shouldbe connected to the ICSP pins (the 2 by 3 pin header) and make sure you plug it in the right way. Theboard must be powered by an external power supply or the USB port.
