MYSBootloader 1.3.0-beta.3

moskovskiy82

Really want to try FOTA with MYSBoatloader but a little bit confused. First - do i have to burn the fuses (i'm using a chinese arduino mini pro 16Mhz) or can simply download MYSBootloader_16MHz.hex from dev brach and i'm good to go?

Another thing - i'm using an MQTT gateway attached to RPi3. Don't really want to change the gateway type - so is there a way to do OTA update? I have a spare UNO which i can connect to a notebook.

gohan

It was mentioned in a previous thread that mycontroller can do fota also through mqtt

moskovskiy82

@gohan ~~Excellent.~~ Searched through the thread but couldn't find any mentions how it can be done via mqtt What about the fuses?

gohan

Just try using mycontroller, the procedure should be the same as the ethernet gateway

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.maximum_size=30720
proMYSBL8.upload.maximum_data_size=2048
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.

@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.
