Hello, PlatformIO Pipz! nice to meet your community!
I use PlatformIO CLI and i have a question: how can i burn a bootloader to my ATTiny85? The clock on Tiny runs very slow, i need to flash it first, that Tiny runs properly.
Thanks, guys!
Hey 
I don’t remember where, but I already explained it. Can’t find 
Let’s start from the beginning.
Could you burn bootloader with Arduino IDE?
Yes, but i want to use only the PlatformIO for all my projects without to installing Arduino IDE. Therefore i am here
I understand. We need Arduino IDE to understand which commands need to run and with wich flags/options. Please go to Arduino IDE settings and enable verbose mode for build/upload operation. Then, you will see the full log. Please paste it on http://pastebin.com and share URL here.
Thanks.
Thanks. Are you familiar with Python?
yes, i hope i have enough knowledge about low level stuff as a designer 
Can your help me with this problem, please?
- Check advanced extra scripting and custom upload tool: Redirecting...
You need to create extra script that defines new target. Let’s name it as uploadboot:
extra_script.py
Import("env")
env.Replace(
SETFUSECMD='$UPLOADER $UPLOADERFLAGS -P $UPLOAD_PORT -b $UPLOAD_SPEED -Ulock:w:0xFF:m -Uefuse:w:0xFF:m -Uhfuse:w:0xD7:m -Ulfuse:w:0xE2:m',
UPLOADBOOTCMD='$UPLOADER $UPLOADERFLAGS -P $UPLOAD_PORT -b $UPLOAD_SPEED -Uflash:w:$SOURCES:i -Ulock:w:0xFF:m'
)
bootloader_path = "/Users/antonkluev/Library/Arduino15/packages/ATTinyCore/hardware/avr/1.1.1/bootloaders/empty/empty_all.hex"
uploadboot = env.Alias(
"uploadboot", bootloader_path,
[env.VerboseAction(env.AutodetectUploadPort, "Looking for upload port..."),
env.VerboseAction("$SETFUSECMD", "Setting fuses"),
env.VerboseAction("$UPLOADBOOTCMD", "Uploading bootloader $SOURCE")])
AlwaysBuild(uploadboot)
platformio.ini
[env:burn_boot]
platform = atmelavr
framework = arduino
board = <BOARD_ID>
upload_speed = 19200
extra_scripts = extra_script.py
Burn bootloder
pio run -t uploadboot
omg, you are the greatest! i will test it on weekend, and then i will tell you if it works…
And once again, thanks for such great work, i very appreciate it!

i did exactly as you said, but i get everytime a problem with atmelavr platform, that is currently not available:
Please wait while upgrading PlatformIO ...

Please remove targets = program line from platformio.ini. Use pio run -t program to upload firmware and pio run -t uploadboot to burn bootloader.
somehow i receiving this error:

*** [uploadboot] Error 1
=============================== [ERROR] Took 2.65 seconds ===============================
this is my .ini now
[env:85.boot]
board = attiny85
extra_script = ./bootloader/extra_script.py
upload_port = /dev/cu.wchusbserial1410
upload_speed = 19200
board_f_cpu = 8000000L
platform = atmelavr
upload_protocol = stk500v1
framework = arduino
upload_flags = -P$UPLOAD_PORT -b$UPLOAD_SPEED
I copied the “empty_all.hex” to my project folder, to be completly independent from arduino ide and updated the link in “extra_script.py” to “./empty_all.hex”
You personally create the problems for self. I wrote for you valid platformio.ini and extra_script.py. Why did you specify upload_protocol = stk500v1? In any case, you can compare 2 versions. See your Arduino output http://pastebin.com/p62Z3sKc. Where is difference?

This is puzzle for you. Try to resolve it 
Because im not familiar with the whole logic that happens behind platformio. This is why Platformio exist and should do all this stuff automaticaly, to make the life easer without to learn lowlevel theory, right? I using upload protocol because i use arduino nano for uploading anything to my attiny, i found this in tutorials on your website. If i do not need this part, just say it to me, im not a computer specialist, i am just a dump designer ) I dont know, what actualy happens if i upload something to the chip, therefore i need your help. Sorry if i do something wrong.
what ive done:
- include in “platformio.ini” the “extra_script” with the right path? yes
- make an “extra_script” with the right path to the “empty_all.hex”? yes
- i used -t uploadboot? yes
everything exact so like you said, excluding the movement of “empty_all.hex” to the root folder of my project
but all the pathes are correct, and there no errors about wrong pathes.
