upload to ESP via Arduino DUE don't work

[steamboating]

I tried to upload code out of the Arduino IDE via a DUE into the ESP-01 like described here:
http://www.instructables.com/id/Use-Arduino-Due-to-program-and-test-ESP8266/?lang=de&ALLSTEPS

With the Arduino IDE 1.6.4 on my Win 8.1 system I can establish a serial monitor connection via the DUE to the ESP and communicate.

I also can upload new firmware through the DUE mirroring program with the ESP8266 Flasher and use it with the LuaLoader through the DUE.

When trying to upload code with the Arduino IDE through the DUE I get the blue LED flashing as serial request but there is no upload connection:

trying to connect
flush start
setting serial port timeouts to 1 ms
setting serial port timeouts to 1000 ms
flush complete
espcomm_send_command: sending command header
espcomm_send_command: sending command payload
read 0, requested 1

I get the above message several times and it ends with

warning: espcomm_sync failed
error: espcomm_open failed

I integrated a
Serial.setTimeout(1000);
into my mirroring program alreeady - still no connection.

When using the FTDI Adapter from an UNO board without the UNO Chip installed I can upload programs to the ESP without problems - even with the 3.3 Volt still from the DUE. During the upload the blue LED on the ESP is flashing much faster than during the serial requests described above - quite obviouse ...

I need a way to program the ESP through the DUE because I have developed a board with an Atmel SAM3X8 (DUE) and an ESP8266 on it as toy robot platform...

Thanks for any help.

Unfortunately I don't have DUE to test this. Can you capture what happens on the serial line using a logic analyzer?

[steamboating]

Thanks for the quick reply!

It's funny that all other ESP programs that I have used before work with this DUE mirroring but not the Arduino IDE...

Unfortunately my logic analyzer is still in the China Post ;-)
Will try to get one from a friend and show what's going on there...

Happens the same to me with MEGA and DUE

[steamboating]

Hello igrr and Pablotis,
I made a quick setup with the MEGA - yes - I get the same problem as I have described above:

"serial monitor" communication through this mirroring prorgam is possible but not the programing.

@igrr
Will still try to get the logic analyser but
maybe you have a MEGA at hands?

I don't have a Mega but I do have a Leonardo somewhere, I think it has two serial ports as well (one over USB and one UART). Can you point me to the mirroring program that you use?

[steamboating]

Thanks for helping us!

I used it as ddescribed here:
http://www.instructables.com/id/Use-Arduino-Due-to-program-and-test-ESP8266/?lang=de&ALLSTEPS

// =======================================================================
#define Serial_ESP Serial3
#define Serial_Debug Serial

#define Serial_Baud 115200

// =======================================================================
void setup() {
Serial_ESP.begin(Serial_Baud);
Serial_Debug.begin(Serial_Baud);
}
// =======================================================================
void loop() {
if (Serial_ESP.available()) {
byte c = Serial_ESP.read();
Serial_Debug.write(c);
}
if (Serial_Debug.available()) {
byte c = Serial_Debug.read();
Serial_ESP.write(c);
}
}
// =======================================================================

You can run it with "byte c", "int c", or "char c"

Similar example can be found on the Arduino-cc homepage:
http://www.arduino.cc/en/Tutorial/MultiSerialMega

void setup() {
// initialize both serial ports:
Serial.begin(9600);
Serial1.begin(9600);
}

void loop() {
// read from port 1, send to port 0:
if (Serial1.available()) {
int inByte = Serial1.read();
Serial.write(inByte);
}

// read from port 0, send to port 1:
if (Serial.available()) {
int inByte = Serial.read();
Serial1.write(inByte);
}
}

I have made a log with an arduino due of the data transmitted during the procces.
I have done two logs, the first uploading a firmware from arduino ide, that didn't upload, and the other using the flash tool, that uploaded succesfully.
https://drive.google.com/folderview?id=0BxPwW0n9dYaFfkVFTy1tUG96QkVCQi1xSC1YdEJ2d2o3Xy1KZ09wbFpoRjdPQnBHVWhVSG8&usp=sharing

I have done it with an Arduino DUE so I don't know if it is accurate enough.

[igrr]

How to interpret this log? I see a lot of '1's...

[steamboating]

@igrr
Looks for me like the only the "send line" from the ESP? The log "Arduino IDE" contains only 1 because nothing comes back . The "ESP8266 Flash Downloader Tool.log"contains some 01 sequences

@pablotis
Maybe you can send a log file with parallel rx and tx signals - maybe as a screenshot?

[pablotix20]

I have uploaded to the same folder 2 new logs that contains data sended from the arduino ide when programming and from the uploading tool, if you want i could make the same with the responses from the esp, the firmware i have uploaded with the tool is the official AT commands.

[steamboating]

Thank you Pablotis for this second upload.
Hopefully igrr knows how to interpret this info...

[pablotix20]

I can also upload the commands of the previous version of the arduino ide, the ones that works

[steamboating]

@pablotis
Which IDE worked for you?
Which ESP version have you used with it?
Is that still downloadable from any place?

Would love to install this for my actual trials. On my own ATMEL SAM3X8 based PCB I have wired the ESP direct to the SAM - this PCB has no FTDI driver and even no connectors for such a connection.

I have an ESP01 which i bought on banggod, the version that works for me is the 1.6.1 of the Arduino IDE, i think you can download it on the relases page but they have removed the link so i don't know how to acces, if you want i can upload it to Google Drive but with my connection it will take 2 houres aproximately.

[steamboating]

The Arduino 1.6.1 is still here:
http://www.arduino.cc/en/Main/OldSoftwareReleases#previous

But which ESP tool version have you used? And where to find that?
