esp8266/Arduino

Arduino IDE for ESP8266

@WhiteHare This isn't documented anywhere, but you may find something useful in this issue: esp8266/Arduino#268

basically the flow is like this:

flash DNS_SD_Arduino_OTA example sketch

after some time, the board will appear in 'ports' menu

Select 'OTA' instead of 'Serial' in Tools > Upload using

You can now do some sketches and flash the sketch. It should be uploaded over-the-air

You also need python installed and in PATH, because the script which does OTA is currently written in python.

@igrr

There are also samples bundled with the IDE which show how to do OTA using an HTTP upload. In some contexts this might be more convenient.

Hi about OTA procedure:

I use the content of BasicOTA.ino in my project and flashed my NodeMCU, serial terminal shows :
M117 Connecting...
M117 192.168.0.120
OTA server at: ESP8266-OTA-22e89:8266

so server look ready

I use the tool python ota_server.py to do OTA to flash a new version of my project

C:\Users\user\Desktop\ld5110>python ota_server.py 192.168.0.120 esp8266.cpp.bin

so terminal display this:

starting up on 0.0.0.0 port 48266
upload size: 437120
sending invitation
waiting for a connection
connection from ('192.168.0.120', 4097)
opening file esp8266.cpp.bin
sending 4096
sending 4096
....
sending 4096
sending 2944
done!

and serial terminal display this:
Update Start: ip:192.168.0.101, port:48266, size:437120
ERROR[0]: No Error

looks fine but atually ESP Fw is not modified even after a restart
do I missed something ?

Thanks

@kireevco

@kathir1951 hey, so looks like my environment and script works fine. tested 3 times

@kathir1951

@kireevco Thanks Nice

Dmitry Kireev

@kireevco

I will test more for linux and mac, and I hope we can have a nice cross-platform build script for toolchain

Ivan Grokhotkov

@igrr

@kireevco for OS X don't forget to add export MACOSX_DEPLOYMENT_TARGET=10.7 (or maybe even 10.6) to the build script.

Dmitry Kireev

@kireevco

@igrr what does it do? (where is it used)

@igrr thank you

Ivan Grokhotkov

@igrr

basically when someone builds an executable on OS X, by default compiler will target the same OS X version. the option i mentioned is to make sure the binary will run on older versions as well

it's used by clang/gcc

Dmitry Kireev

@kireevco

ah, that’s for gcc?

got it

thank you. mac specific.

Ivan Grokhotkov

@igrr

there's also an equivalent GCC/clang command line option, -mmacosx-version-min, but i find it easier to set MACOSX_DEPLOYMENT_TARGET once in the environment rather than making sure -mmacosx-version-min gets passed into each configure script correctly.

just my 2 cents, i remember people having issues when I built toolchain without this option

Dmitry Kireev

@kireevco

@igrr appreciate it!

I like esp-open-sdk because it’s open… but it doesnt’ work on windows yet :(

doesn’t build..

Ivan Grokhotkov

@igrr

yeah, i saw pfalcon is reluctant to fix that, despite the fact that windows has about 80% user share in the esp8266 community

Dmitry Kireev

@kireevco

yep :(

I’m trying to arrange build environment here https://github.com/kireevco/packages/tree/master/esp-open-sdk/windows

tried cygwin, mingw… there are issues… and testing cycle is pretty long .

(just complaining) :-D lol.

Ivan Grokhotkov

@igrr

yeah, i remember it took me a few nights to troubleshoot everything and build windows toolchain on my old laptop

last time i had to do this, i got myself a D4 instance from azure cloud

Dmitry Kireev

@kireevco

I got myself a host on hetzner, and built a proxmox host

you did a great job, thanks for your help too :)

Ivan Grokhotkov

@igrr

ok, actually windows is down to 67%

esptool-0.4.5-linux32.tar.gz: 1103 downloads
esptool-0.4.5-linux64.tar.gz: 5845 downloads
esptool-0.4.5-osx.tar.gz: 5592 downloads
esptool-0.4.5-win32.zip: 27600 downloads

Dmitry Kireev

@kireevco

nice data

still, lots of windows users

@igrr

@luc-github what does the serial log show after (and during) restart?

Luc

@luc-github

@igrr I use swap to avoid serial garbage when I send a retart command and I do not have serial enable few seconds after restart for same reason, so If there is no obvious mistake in procedure I describe to you - now I will dig using simple sample and report the output - thanks for your help

Luc

@luc-github

I used BasicOTA.ino just add an output at each loop and a delay(2000) and same output - upload ok - ERROR[0]: No Error but after sample continue and do not reset - here the output
OTA server at: ESP8266-OTA-22e89:8266
Ready
First version
First version
First version
Update Start: ip:192.168.0.101, port:48266, size:346816
ERROR[0]: No Error
First version
First version
First version
if I restart it is like no upload happened :
OTA server at: ESP8266-OTA-22e89:8266
Ready
First version
First version
First version

the uploaded is same code but with output "second version"

Luc

@luc-github

from another hand, if I use WebUpdater.ino, it works!
after upload the reset happen and new sketch is used - weird

Ivan Grokhotkov

@igrr

since this line doesn't run, apparently there is some error:
Serial.printf("Update Success\nRebooting...\n");

can you please uncomment this line in Updater.cpp and try again?
//#define DEBUG_UPDATER Serial

Updater.cpp is in cores/esp8266 directory

Luc

@luc-github

I have compared code and found difference between ESP8266HTTPUpdateServer.cpp and ArduinoOTA.cpp, first one use if(Update.end(true)) second use if(Update.end())
by changing if(Update.end(true)) in ArduinoOTA.cpp first time update succeed but go into dead loop second try it worked

ok will do #define DEBUG_UPDATER Serial
