AND FINALLY IT WORKS !!! Mr. EasyIoT "in add mysensors section" tutorial i suggest you to tell to check MyConfig.h for same channel and settings.

So I have also went the route of using arduino as isp
Physically they are set up nano with isp sketch to programminipro 3.3v
where do I go to use the avr coding the set low fuse and stop brown out?
I am at a loss!

Hi :

I think that i fried my Arduino 3.3v... anyone can help me ?

1.- Test Read

avrdude -P /dev/ttyUSB0 -c usbasp -p m328p

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.01s

avrdude: Device signature = 0x1e950f

avrdude: safemode: Fuses OK (H:05, E:DA, L:FF)

avrdude done. Thank you.

2.- lfuse

avrdude -P /dev/ttyUSB0 -c usbasp -p m328p -U lfuse:w:0x62:m

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.01s

avrdude: Device signature = 0x1e950f
avrdude: reading input file "0x62"
avrdude: writing lfuse (1 bytes):

Writing | ################################################## | 100% 0.01s

avrdude: 1 bytes of lfuse written
avrdude: verifying lfuse memory against 0x62:
avrdude: load data lfuse data from input file 0x62:
avrdude: input file 0x62 contains 1 bytes
avrdude: reading on-chip lfuse data:

Reading | ################################################## | 100% 0.00s

avrdude: verifying ...
avrdude: 1 bytes of lfuse verified

avrdude: safemode: Fuses OK (H:05, E:DA, L:62)

avrdude done. Thank you.

3. Last step... efuse. My arduino it's dead !!

avrdude -P /dev/ttyUSB0 -c usbasp -p m328p -U efuse:w:0x07:m

avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude done. Thank you.

Also, trying with 19200, but does not work :

avrdude -P /dev/ttyUSB0 -b 19200 -c usbasp -p m328p -U efuse:w:0x07:m

avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.


avrdude done. Thank you.


Any clue, please ?

Thank you !

Fixed !!!

I bringing back my Arduino Nano to life, with this command :

avrdude -c usbtiny -p m328p -U lfuse:w:0xFF:m -B250

Very important parameter was the -B250

Extracted solution from this forum, maybe can help to somebody
