I picked up an R4 Uno Minima for the main purpose of programming ATTiny85s for guitar pedal bypass relays. It seems to take the ArduinoICSP sketch fine, but then fails when uploading the other sketch for the ATTiny. There's definitely a possibility I'm doing something wrong as I'm new to these things, but have used older models for the same purpose previously. I just got to thinking maybe these don't function that way?
Under tools you need to set the programmer as Arduino as ISP. When you are uploading to the ATtiny85 you will need to select the board as ATtiny25/45/85 and then the clock - internal or external and frequency. Once you have setup the board then you need to burn the bootloader and then you can compile and upload your sketch via the upload via programmer option.
I'm still not having any luck. I plug in my R4 and then upload the ArduinoISP sketch to it and get these results:
Sketch uses 58128 bytes (22%) of program storage space. Maximum is 262144 bytes.
Global variables use 4860 bytes (14%) of dynamic memory, leaving 27908 bytes for local variables. Maximum is 32768 bytes.

Then I switch my board over to ATTiny85, and select the programmer as "Arduino as ISP" and then try to upload the sketch which results in:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03

Hi @sgtrutters. I know it has been a long time but I found this topic while I was doing some research on using the UNO R4 Minima and UNO R4 WiFi boards as "Arduino as ISP" programmers and thought I should share my findings here in case you are still interested, and for the benefit of others who might find this forum topic while researching the subject.
I discovered the error you experienced was caused by a bug in the "ArduinoISP" sketch. I have fixed the bug:
The fixed version of the example will be in the next release of Arduino IDE. You can download it now here:
Another thing to note is that you must select Tools > Programmer > Arduino as ISP (ATmega32U4) instead of Tools > Programmer > Arduino as ISP from the Arduino IDE menus when using an UNO R4 Minima or UNO R4 WiFi board as an "Arduino as ISP" programmer.

Hi, thanks for fixing this! I was just about to try to program my first ATtiny85. 
I've installed the attiny by David A. Mellis package and now can select the ATtiny85 and set the programmer to Arduino as ISO (ATmega32U4).
A question though. I use IDE 2.2.1 with my R4 Minima.
Is the pin-layout the same as the Uno? (11, 12, 13)
(and a resistor/led on 7, 8, 9)
p.s. If interested, I need to use the ATtiny85 because my NeoPixel Stick (still) doesn't support the 'new' chip in the R4 series. 
Maybe consider using the FastLED library instead which has been updated to work with the Uno R4 boards
Hi and thanks.
I tried, but it gave an compile error. After searching they said it was still not supported.
Also, on their own github it's still an open issue. Link
The page you linked to dates from May
Take a look at this page GitHub - arduino/uno-r4-library-compatibility
Please post the sketch that caused errors with the Uno R4 and details of the version of FastLED that you used
You are welcome. I'm glad if the fix will be useful to some people. I think it is pretty cool to have the ability to so easily make a DIY ISP programmer and like to see as many boards as possible be supported for use as an "Arduino as ISP".
That is correct.
You can also make connections to the 2x3 ICSP header on the UNO R4 Minima instead of the normal pin headers, just the same as on the UNO R3 and similar boards, if you find that to be convenient.
Hi UKHB,
Thanks. I get this error: (note that I shorted the filepath)
\Arduino\libraries\FastLED\src/led_sysdefs.h:61:2: error: #error "This platform isn't recognized by FastLED... yet. See comments in FastLED/led_sysdefs.h for options."

What sketch were you compiling and what version of FastLED do you have installed ?
Thanks!
I really think this\your work is used at lot more then you even think!

Oh yeah, that's true.
Version 3.6.0 (by Daniel Garcia). The link linked to the same Github so I guess this should be the right version.
The code on the github page, with only the nr of LEDs set to 8.
#include <FastLED.h>
#define NUM_LEDS 8
CRGB leds[NUM_LEDS];
void setup() {
FastLED.addLeds<NEOPIXEL, 6>(leds, NUM_LEDS);
}
void loop() {
leds[0] = CRGB::White; FastLED.show(); delay(30);
leds[0] = CRGB::Black; FastLED.show(); delay(30);
}
Edit: I did tried using "FastLED NeoPixel Library" this afternoon as well, but this one failed on the FastLED lib you told me about.
That sketch compiles fine for me with either the Uno R4 WiFi or Uno R4 Minima as the target and version 3.6.0 of the FastLED library by Daniel Garcia installed
I am using version 2.2.1 of the IDE but the IDE version should make no difference
In led_sysdefs.h there is a specific reference to the Renesas processor versions of the Uno
#elif defined(ARDUINO_ARCH_RENESAS) || defined(ARDUINO_ARCH_RENESAS_UNO) || defined(ARDUINO_ARCH_RENESAS_PORTENTA)
#include "platforms/arm/renesas/led_sysdef_arm_renesas.h"
Which board have you got set as the target in the IDE ?
Arduino UNO R4 Minima
Here are parts of the output when I compile the code for the R4 Minima. Truncated output due to the limit on the size of data that can be posted

I can't see anything obviously wrong
You can find the bard version number by opening the board manager in the IDE and seraching for Minima
But from your output it seems that you are using 1.0.5
As a matter of interest, does your led_sysdefs.h file have an entry for the Renesas processor ? See post #14 above
1.0.5 indeed.
No it does not! It seems you're on to something.
The Github source does have that and my file does not.
Ahhh.
The latest stable is 3.6.0 from May and that change is from July.
I am not aware of doing anything out of the ordinary in respect of my Uno R4 board installation but updating led_sysdefs.h has got to be worth a shot for you
