How to flash ATtiny10?

Question

I am trying to make LED blinker for my project using ATtiny10, I try Blink example from Arduino IDE. I also made custom PCB:

I even found instructables link, how to program it:https://www.instructables.com/How-to-Program-ATtiny10-With-Arduino-IDE-A-Compreh/ I followed this tutorial, programmed my Arduino UNO to work as TPI programmer (specific attiny10 programming interface), then connected SPI pins of UNO to RESET, CLK, MISO, MOSI pins on attiny. I installed attiny board lib on arduino ide, downgraded all versions just like in tutorial and tried flashing it, but got serial timeout error.

So it does not work for me, my ATtiny doesn't respond. Maybe there are some other ways, how to program it?

Update: I tried using AVRISP mkII to at least detect my attiny10 using avrdudess. I switched jumper from 3.3 to 5 V on avrisp mkII, I also added 2.2 uF cap on Reset line, left Mosi line N.C., tried switching R21, R13, R14, R28 resistors to 0 Ohm ones. No luck there, tried flashing simple Assmebly code using microchip studio but always get device not found error. At this point I am starting to think that mouser made a mistake and instead of Attiny 10 send me something completely different.

Update 2 I have tried multiple methods to flash the chip, using Arduino Uno as TPI programmer, using Arduino Nano as TPI programmer, using AVRISP MKII and AVRDUDESS, using AVRISP MKII and Microchip studio, added multiple Arduino IDE libraries for ATtiny10 board. Nothing seems to work, my ATtiny10 just don't want to wake up or communicate at all. I even tried connecting +12 V on Reset line, in hopes that it was somehow pre programmed with Reset line as GPIO. Nothing seems to work.

Answer 1

The ATtiny10 is programmed with the Tiny Programming Interface (TPI).
This uses RESET, TPIDATA and TPICLK.

This is different from other Atmel parts using SPI programming, and you need a compatible programmer.
I used an official AVRISP MKII for example.

Since this chip has a very low pin count and you will probably be reusing pins, you need to make sure the programming interface can still be used.

This part will never have a bootloader, using the standard Arduino IDE may not work.

You can find an application note on TPI, with some of the inner workings. This may be useful when designing you board for multi-purpose pins. And references to AVROSP, which is another application example to use an ATmega as programmer.

I should mention that using Arduino code in this part, with 1024 bytes of flash and only 32 "registers" of ram will not be possible. In fact, if you want to use C at all you need to jump through significant hoops to keep the process image tiny.
Eg: The stackframe for main needs to be omitted for example (takes 8 bytes)
