I am migrating from Windows 10 to Ubuntu (I did a test migration on two laptops with no problems).
I can program UPDI devices (eg ATtiny1604) with the pymcuprog script and modified serial card (proves I successfully installed PlatformIO as Visual Studio extension, and successfully loaded the python script as a local instance).
I can program an Aurduino Nano with no problems but I get an avrdude syntax error when I try to program an ATtiny85 either using Arduino as ISP or a USBASP programmer (yes, I’ve installed 99-platformio-udev.rules file to support this programmer).
I’ve checked that the avrdude.conf file is where it expects it to be.
Please can you suggest what I may check / change.
Here’s all the details…
Source
#include <Arduino.h>
// put function declarations here:
int myFunction(int, int);
void setup() {
// put your setup code here, to run once:
int result = myFunction(2, 3);
}
void loop() {
// put your main code here, to run repeatedly:
}
// put function definitions here:
int myFunction(int x, int y) {
return x + y;
}

A look at the config file location…
peter@XPS-8700:~$ cd /home/peter/.platformio/packages/tool-avrdude/
peter@XPS-8700:~/.platformio/packages/tool-avrdude$ ls
avrdude avrdude.conf package.json
peter@XPS-8700:~/.platformio/packages/tool-avrdude$
If I rename the file, I get the following error message (I was hoping the file would be re-created in case it was some how mal-formed)…
avrdude: can't open config file "/home/peter/.platformio/packages/tool-avrdude/avrdude.conf": No such file or directory
avrdude: error reading system wide configuration file "/home/peter/.platformio/packages/tool-avrdude/avrdude.conf"
*** [upload] Error 1
Could it be a privileges thing - how to check?
The avrdue.conf file is too large to paste into this topic but I could copy out a section if directed.
Looking in the config file at line 402, I can see…
# Overall avrdude defaults; suitable for ~/.config/avrdude/avrdude.rc
#
default_parallel = "/dev/parport0";
default_serial = "/dev/ttyS0";
default_spi = "";
# default_bitclock = 2.5;
Line 402 is the default_spi setting. What should this be?
Thanks
