[Solved] FOTA Not Working

Soloam

I tried to flash the several Bootloader into one of the ATMEGA that was not working, the results are strange:

FTDI Access:

Arduino UNO Bootloader: OK
ATMEGA on a Breadboard (8Mhz Internal Clock) OK
MysBootloader 16Mhz OK
MysBootloader 8Mhz NOK
MysBootloader 1Mhz OK

I would assume that the problem was something on the config, but that would not explain way it works on some ATMEGA, and on others not... Can it be defective units (ATMEGA)? Only not working the 8Mhz??

My boards.txt from github Dev brantch... I only had to change 3 lines to make it work... in Linux at lest we need this on the sketch folder (MYSBL.upload.tool=arduino:avrdude, MYSBL.bootloader.tool=arduino:avrdude, MYSBL.build.core=arduino:arduino, MYSBL.build.variant=arduino:standard)

The complete Log on trying to load the sketch with the FTDI to the ATMEGA! I don't know if not working with the FTDI has anyting related with not being able to flash with the MyController, but it's strange... Just giving all info as possible to try to get some help on the problem.

avrdude done.  Thank you.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Thank You

Can It be my version of the Arduino AVR Boards? I have 1.6.21, and the same occurs on 1.6.20.

Thank You

Soloam

Ok, at this point I can't access by FTDI to the 8Mhz, all the other frequencies ar working... I only tested the FOTA with the 8Mhz, so I'll teste it again today with the 1Mhz and post back the results.

Soloam

I can confirm that FOTA is working on all frequency, except 8Mhz... I can't get it working on FOTA or FTDI on the 8Mhz version of MYSBootloader!

Can any one help me with this?

Thank you

tekka

@soloam I assume 115200 baud@8Mhz could be an issue, decreasing it to 57600 may help (i.e. in mysbootloader & boards.txt settings)

Soloam

@tekka said in FOTA Not Working:

57600

hello @tekka I tested out with:

57600
38400
19200
9600
4800
2400

None worked, strange that is working on the 16Mhz and 1Mhz, and only the 8Mhz is giving problems... exactly the one that I wanted to use... lol

Thank You

@soloam said in FOTA Not Working:

exactly the one that I wanted to use.

Murphy's law :sweat_smile:

tekka

@soloam When you tested the different baud settings, did you also change it in mysbootloader and recompiled it?

Soloam

Do you mean over here @tekka?

/* set the UART baud rate defaults */
#ifndef BAUD_RATE
	#if F_CPU >= 8000000L
		#define BAUD_RATE   115200L
	#elif F_CPU >= 1000000L
		#define BAUD_RATE   9600L   // 19200 also supported, but with significant error
	#elif F_CPU >= 128000L
		#define BAUD_RATE   4800L   // Good for 128kHz internal RC
	#else
		#define BAUD_RATE 1200L     // Good even at 32768Hz
	#endif
#endif

No, I will try it... Can I do it in "Atom"? any special settings?

Thank You

tekka

@soloam Yes, that's the correct location (if BAUD_RATE is not set via compiler settings).
Sorry, but I have no experience with Atom.

Soloam

@tekka it worked :) Thank you for your assist, it was my first time doing this... so... :)

I made the change to HW.h to

#ifndef BAUD_RATE
	#if F_CPU >= 16000000L
		#define BAUD_RATE   115200L
	#elif F_CPU >= 8000000L
		#define BAUD_RATE   57600L
	#elif F_CPU >= 1000000L
		#define BAUD_RATE   9600L   // 19200 also supported, but with significant error
	#elif F_CPU >= 128000L
		#define BAUD_RATE   4800L   // Good for 128kHz internal RC
	#else
		#define BAUD_RATE 1200L     // Good even at 32768Hz
	#endif
#endif

Compilled the new bootloader, and replaced it on the Arduino IDE folder... Flashed the new 8Mhz Bootloader to my node and now FTDI works... When I get home I'll test out FOTA and post back the results.

Will you change the GitHub Repo to take into account this change? Or is this a local problem only to me? Do you want me to submit change the code and hex file and submit a change request?

Thank You

tekka

@soloam well done! Yes, please go ahead and submit a PR with the necessary changes. I will review it later this week.

Soloam

@tekka FOTA and FTDI now working on 8Mhz Bootloader... PR submited!

Thank you for your help

Soloam

Just to end and close the topic, @tekka great work on the Bootloader and @jkandasa great work on MyController... Thank you
