Node reboot issue

[slt1]

One more thing that may be helpful ... when the node "hangs" the status LED is blinking rapidly.

[slt1]

After some looking around i found this ..
https://arduino.stackexchange.com/questions/2922/watchdog-timer-stuck-in-restart-loop-green-led-flashing

I flashed Optiboot bootloader and that worked.

I flashed MYSBootloader again and now it does work - I am fairly certain this bootloader was causing the issue before ?!? Oh well - it works now !

I flashed with Arduino Pro Mini 5V 16Mhz and that caused the reset hang

So it seems to be an issue with the default Arduino Pro Mini bootloader that comes with Arduino IDE.

Hope this helps anyone else experiencing same issue.

I have exactly the same problem, although I actually have the MYSBootloader installed.

This is also a 5V pro mini.

I'll check my boards.txt file later, maybe I have incorrect settings that don't work with 5V 16 Mhz units.

@maghac I was still having issues with MYSBootloader. This was using the version bundled with MYSController - in a folder called "MYSController_1_0_0beta".
I found one on github here https://github.com/mysensors/MySensorsBootloaderRF24
It seems to be a newer version.
I downloaded that one and setup the 16MHz from their boards.txt file and so far this seems to work.

@slt1 Thanks for the tip - I grabbed the files from the development branch - was that the one you were using? I found three versions of the .hex file - 1Mhz, 8Mhz and 16 Mhz.

Now I am unable to upload a sketch after flashing the MYSBootloader. It only works if I go back to the normal Pro Mino bootloader.

[slt1]

@maghac
The previous version (bundled with MYSController) I was using would not allow me to upload sketches using FTDI cable after flashing the MYSBootloader. It also had the node reboot issue.

The latest dev branch from github link does allow me to now and the node reboot works too !

I copied all 3 hex files into a MySensors folder (C:\Program Files (x86)\Arduino\hardware\arduino\avr\bootloaders\MySensors)

They only had one board in the boards.txt - I only have 5V 16MHz Pro Mini's so changed link to hex file in the sample boards.txt they gave and added that to bottom of boards.txt file in Arduino install dir. boards.txt content I copied is ..

@maghac I tested a bit now again and see there is still an issue when uploading sketch using USB Asp cable. I am getting this error :

avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.

However, that is non-critical for me as I only want to flash the bootloader using USB Asp cable and then I use the FTDI Cable for sketch uploads

MYSBootloader.hex is from the master branch of MYSBootloader 1.3.0-beta.3, the other two are from the development branch.

Doesn't matter which one I use, I can never get my 5V 16MHz boards to accept a new sketch via FTDI cable. I have to go back to the standard bootloader.

Just realized I should probably post this in the Wireless Programming thread instead.

[slt1]

@maghac I copied and tried your settings for

proMYSBL16.name=ATmega328 16Mhz MYSBootloader 1.3 beta DEV

and I get errors like this uploading via FTDI cable ...
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x2c
etc

If you want to try my settings then change the 16Mhz settings to this -

#ATmega328 16Mhz MYSBootloader 1.3 beta DEV
proMYSBL16.name=ATmega328 16Mhz MYSBootloader 1.3 beta DEV

And rem Arduino IDE needs to be closed and restarted after changes

@slt1 Thanks, I'll give it a try next time. Now the node is actually mounted in a place where it's difficult to physically reach it (which is why I wanted to enable OTA updates of course).

The only difference between your entry and mine is the extended_fuses line, isn't it?

Whenever I use your settings (extended_fuses=0x06), avrdude gives me a warning and instructs me to change the value.

[slt1]

@maghac In your one configured as "MYSBootloader 1.3 beta DEV" which uses the MYSBootloader_16MHz.hex there is also a difference in upload.speed.

So, now I have the same problem with a 5V pro clone.

With normal bootloader:

• the board gets stuck in a loop with flashing LED when i try to reboot it.

With MYSBootloader (1.3.0-beta.4 or 1.3.0-beta.3):

• unable to upload a new sketch using the FTDI cable
• node doesn't seem to get recognized properly by the GW or the controller. I see it's contiously sending "mysensors-out/10/255/4/0/0 FFFFFFFFFFFFFE400102" messages on MQTT, which I think is when it's checking for a new firmware, but nothing on the serial monitor. This makes it impossible to upload a new sketch OTA.

Any ideas on how to troubleshoot?
