MYSBootloader 1.3.0-beta.3

[moskovskiy82]

Yes thank you for the tip! Mycontroller works.
For Mini Pro - no fuses are needed. Just download the hex - rename and flash.
What about the nano?
Looking at boards.txt i see only two difeerences

Nano
nano.menu.cpu.atmega328.bootloader.low_fuses=0xFF
nano.menu.cpu.atmega328.bootloader.extended_fuses=0xFD

Mys
proMYSBL.bootloader.low_fuses=0xF7
proMYSBL.bootloader.extended_fuses=0x06

But at the same time PRO mini is same as nano... So can also flash straight away?

[moskovskiy82]

Nano also doesn't need any fuses. So everything works. Except to begin the flash procedure i have to unplug and plug the node. Is this intended behaviour? Otherwise i only see in MQTT one line of code and no response from node

[gohan]

Is the node doing any kind of sleep?

[moskovskiy82]

No it's powered off mains so no sleep functions added

[gohan]

I think you have to issue a reboot node from the mycontroller or myscontroller to have the OTA start

[moskovskiy82]

@gohan So is it first reboot. Or start flashing - reboot?

[gohan]

You assign firmware to upload to node and then you send a reboot, if I remember correctly

[jkandasa]

@moskovskiy82 If you use MyController, Yes, you should assign the firmware for the node and send reboot.

[moskovskiy82]

@jkandasa Thank you!

One more question. Now need to use a 3,3V arduino Pro (chinese version) (Nano and 5V version flashed via the uno without a hitch)

This is what i put into boards.txt The MYSBootloader_8Mhz.hex is from the dev branch

proMYSBL8.name=ATmega328 8Mhz MYSBootloader

proMYSBL8.name=ATmega328 internal 8Mhz with MYSBootloader
proMYSBL8.upload.tool=avrdude
proMYSBL8.upload.protocol=arduino

proMYSBL8.upload.speed=57600
proMYSBL8.bootloader.tool=avrdude
proMYSBL8.bootloader.low_fuses=0xE2
proMYSBL8.bootloader.high_fuses=0xDA
proMYSBL8.bootloader.extended_fuses=0x06
proMYSBL8.bootloader.unlock_bits=0x3F
proMYSBL8.bootloader.lock_bits=0xFF
proMYSBL8.bootloader.file=MySensors/MYSBootloader_8Mhz.hex
proMYSBL8.build.mcu=atmega328p
proMYSBL8.build.f_cpu=8000000L
proMYSBL8.build.board=AVR_UNO
proMYSBL8.build.core=arduino
proMYSBL8.build.variant=standard

Tried to flash the mysbootloader but get the following error

Error while burning bootloader.

[luizrrocha]

@moskovskiy82 My boards.txt specify bootloader.low_fuses=0xF7 as the Arduino being programmed has a crystal on board.

One other thing: I built my own programming board, to support programming ATMega 328p chips and Pro boards in 3.3v@8MHz and 5v@16Mhz... I used a switch and a level converter board to connect the Uno ICSP port to the pins of the Pro.

Uno pins are 5V output, they would burn the input pins of the 3.3v Pro chip, did you account for that ?

[gohan]

You can use 5v to program a 3.3v pro mini as the chip is the same, one is only clocked down to 8Mhz in order to be stable at 3.3v

[luizrrocha]

@gohan I beg to differ. On Page 299 of Atmel's ATMega 328p datasheet you can verify that the Absolute Maximum Ratings table states : "Voltage on any Pin except RESET with respect to Ground . . . . . . . . . .-0.5V to VCC+0.5V" which adds to 3.8V for a 3.3V Pro.

And also: *NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Perhaps you have mistaken the Pro for the NRF24L01+ radio which is supplied by 3.3v but has 5Volt tolerant inputs ?

Otherwise there would be no need for those USB to FTDI boards with 3v3/5V selection jumpers ...

[gohan]

I programmed the pro mini with 5v and it worked. Maybe I was lucky. The 3v ftdi adapter is mandatory for esp8266 for example.

[A Former User]

@tekka for OSX, the sequencing of flags matters. So, line 45 can be:

$(PROJECT).o: $(PROJECT).c
"$(BINPATH)avr-gcc" $(CFLAGS) -I$(INCLUDES) $< -o $@

can be improved to

$(PROJECT).o: $(PROJECT).c
"$(BINPATH)avr-gcc" -I$(INCLUDES) $(CFLAGS) $< -o $@

and it all works.

Also, if anyone is getting error for "avr-gcc" not found, then just add the path to avr-gcc in your path.

[tekka]

@Bhavin-Doshi Thanks for reporting - could you prepare a PR?

[tekka]

@Bhavin-Doshi PR merged. Thank you!

[nagurao.basude]

@tekka, I am planning to move from MySensors v2.0.0 to v2.1.1, do I need to use the updated MYSBootloader? Currently I am using MYSBootloader 1.3 pre-relase (https://forum.mysensors.org/topic/3453/mysbootloader-1-3-pre-release-myscontroller-1-0-0beta).

Can you please also help me understand the differences in the low_fuses and high_fuses values in the older version of bootloader and the latest version?

[tekka]

@nagurao.basude no, you don't need to but the new version has some stability improvements. The fuse differences are to better match HW (osc type) & clearing eeprom.

[Nca78]

Hello, has someone used the 1MHz precompiled bootloader ? If yes what baud rate did you use to communicate via serial ?
I flashed it on a node but I can't upload any script ("not in sync" error). If I believe HW.h it should be 9600 bauds but I have tried hat and nearly every baudrate with no luck.
I had no problem using the 8MHz version.

The only way I could use the 1MHz bootloader at the moment is to flash the hex file containing both bootloader and script.
Sorry to ask this stupid question, I wanted to compile the bootloader but Internet connection is nearly down and I can't even download Atmel Studio :(
