[solved] Is my pro micro board gone??!

Using Arduino IDE 1.x
1

I started to work with this board and windows didn't recognized it, so I had to install the driver.

After different efforts to install sparkfun driver. I found a video on YouTube showing how to upload the bootloader to Arduino chip.

First time it worked and then the reset pin of the micro pro isn't working anymore.

Because I'm connecting pin 10 of the uno which the programmer board to rst pin of the pro micro board.

It used that LEDs work when I remove the wire of the rst pin. And dim when I connect the pin.

Now, it doesn't matter whether I connect or remove the pin, the LEDs are working all the time.

\Is the pro micro gone??

Hi Wolfrose,

my crystal ball is a little dirty today :wink: - can you describe in more details what you have done -
containing all information about the connections you have done and tell us what instructions you have used?

just for your information - all information you need for normal operation of original arduino / genuino boards are available from this webside here - (arduino.cc) - no need to use thirdparty tutorials - sometimes they are misleading!

you are saying you are using a micro pro?!
i did not find this on the Arduino Product Page -
so please insert a link to the product page coresponding to your board!

hi Stefan,

thank you for reply,

well this is a Chinese clone .. looks cool and interesting.

it's available from many sellers except Arduino .. I guess.

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

this particular board has some bootloading issues
there are specific instructions on sparkfun website, which requires that you restart you windows in advanced mode and disable driver enforcement signature .. which I don't know its roll to upload the bootloader. so it didn't work with me.
so I watched a video on YouTube which I explains a good information to use the uno board to program other boards or chips with ArduinoISP code.
Burning Arduino (328/168) Bootloader with Arduino Mega (ATMega1280)!
I learned from this video how to upload the bootloader to another board.
So, I followed the information in the video and it worked with me at the first time and the windows installing the driver was going on !! I was happy for a short time ..
then, the driver just gone and I can't upload the code anymore!!

Because ............ you know what !! it worked :slight_smile:

I uploaded the bootloader with the Arduino nano.

Thank you ..

Hi Wolfrose,

good it worked for you :slight_smile:
(please mark the thread with [solved] in the title of your first post)

but i think you should be able to burn the bootloader as often as you like...
if you are interested to dive some deeper into bootloader you can read the
Hacking / Bootloader section
and the information in the
Bootloader article from Nick Gammon
