avrdude done.  Thank you.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

i managed to upload a program the first time, no problem at all, but i forgot to upload a bootloader before uploading the sketch, maybe that's a issue?

i've been trying to erase the memory on the attiny directly throw avrdude but i'm really inexperience with it and i think it doesnt recognize the attiny neither.

all the wiring and programmer/target-board have been checked and re-checked.

i've tried everthing i was able to find, with no luck

if you're willing to help i would be so grateful

I will presume you have the "Arduino as ISP" sketch installed on the UNO as without it you wont get too far.

A schematic of how you have it hooked up (not a cut and paste from elsewhere) would be nice to see.
Even hand drawn works.

Any pictures you have (decent and no blurry cockroach with coloured blurry lines coming from it. attached).

If everything is correct it is possible to burn the bootloader again (make sure the correct chips is selected)

Occasionally you may also need something to reset the chip fuses like an HVP but I have not needed that yet even with a mistake on the bootloader on my part.

[SUPERWESTER]

indeed, the programmer is set to arduino as ISP.

im working on the IDE v1.8.4

schemtaic of my setup attached.

thanks for replying

I cannot see the capacitor in the blurry cockroach.

BTW that's not really a schematic.
Hard to tell but possibly VCC or ground wrong way around ? (too blurry)

Its a start but not quite good enough just yet to make any real assumptions.

are this pictures more useful?

the positive of the capacitor is connected to the reset. negative to ground.

my bad, im still learning the correct terms.
is diagram more apropriate?

[Ballscrewbob]

The only thing I can see is where you have the 5V supply as that is normally AREF it should not make a big difference but it might. Try putting that on the actual 5V pin instead.
Its a clone so maybe its correct but having it on the correct 5V wont harm it.

It is possible you burnt the fuses wrong with the bootloader.
Also which cores are you using as that could also make a difference.
Not all bootloaders are the same for the ATTINY (as I found out with some ATTINY13)

yes it's a clone. I've tried it on the "normal" 5v output. I started trying with my original UNO, same result.

for the cores i used the ones specified in this guide High-Low Tech – Programming an ATtiny w/ Arduino 1.6 (or 1.0)

how can i fix the fuses?
also... is there a way to erase the memory on the attiny? any way of doing it using avrdude directky?

[Ballscrewbob]

Those cores are quite old.

I found THESE quite useful too.

There are a few variant cores and by accident I think one of them fixed my ATTINY bootloader mistake although I would not know how to replicate it apart from trying different cores and clock speeds.

The memory on the ATTINY is erased when a new sketch is uploaded so uploading something simple such a "bare minimum" example would clear it out.

just tried them but same result

i think i will have to try with an programmer board to make this work
i really didnt want to spend those extra bucks but it seems its the only way

thanks for all the help!!!
