Hey all,

I've compiled the bootloader and was able to install it with Arduino as ISP to a Nano. I couldn't find the lines necessary for the Nano in boards.txt so I created this:

##############################################################

nanomysbootloader.name=Arduino Nano MYSBootloader

nanomysbootloader.upload.tool=avrdude
nanomysbootloader.upload.protocol=arduino

nanomysbootloader.bootloader.tool=avrdude
nanomysbootloader.bootloader.unlock_bits=0x3F
nanomysbootloader.bootloader.lock_bits=0x0F

nanomysbootloader.build.f_cpu=16000000L
nanomysbootloader.build.board=AVR_NANO
nanomysbootloader.build.core=arduino
nanomysbootloader.build.variant=eightanaloginputs

## Arduino Nano w/ ATmega328
## -------------------------
nanomysbootloader.menu.cpu.atmega328=ATmega328

nanomysbootloader.menu.cpu.atmega328.upload.maximum_size=30720
nanomysbootloader.menu.cpu.atmega328.upload.maximum_data_size=2048
nanomysbootloader.menu.cpu.atmega328.upload.speed=115200

nanomysbootloader.menu.cpu.atmega328.bootloader.low_fuses=0xFF
nanomysbootloader.menu.cpu.atmega328.bootloader.high_fuses=0xDA
nanomysbootloader.menu.cpu.atmega328.bootloader.extended_fuses=0xFD
nanomysbootloader.menu.cpu.atmega328.bootloader.file=MySensors/MYSBootloader.hex
nanomysbootloader.menu.cpu.atmega328.build.mcu=atmega328p

Is this correct? Besides, on some devices I cannot program over serial anymore now, only through another ISP. Could that be caused by incorrect settings? Is it possible to recover from that?
The error I'm getting is this one:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x32

Thanks and happy easter!

@tekka I checked but MY_OTA_FIRMWARE_FEATURE wasn't enabled. Also I tried Mysensors 1.4.1 and 1.5.2 but same result. Can't get it to work;-(

Can I get in on the test too?
Thanks!

Hey Tekka,

Tried clearing both eeproms, still same problem. Actually tried two completely new nano's and same problem again...

No more news on this?;-)

Hi Oitzu,

Just tried that, same result...

Hi Tekka,

Please see here my log:
MySensors_20151109-085110.log

Also yes, all my nodes are running the same version from git.

Cheers,

Rene

Hi and thanks again;-)

Ok I've got the bootloader and sketch on the node. I also see it in my gateway using MYSController. However when I try to reboot it just starts sending a lot of messages but doesn't reboot. Neither do I seem able to update the firmware, any clue?

I also added the line 'boolean process();' to the start of the loop.

Rene

Hey thanks for the advice.

I actually programmed the MYSbootloader with another Arduino (ISP). Now the programmed Arduino isn't responding anymore. It does work again if I restore the original bootloader. Should I perhaps change something in the fuse settings?

Thanks.

Rene

Hey there,

I read that it is possible to update firmware OTA using MYSBootloader.
Is this also possible with Arduino Nano (clone)? I cannot find anywhere how to burn this bootloader, if possible. If not, what is the best alternative?

Thanks a lot!

Rene
