Syntax Error

[mlksahib]

I am trying to upload bootloader to new atmega328p-smd version but ide shows (in verbose output) syntax error in avrdude.conf file at line 421.
Another error is that the said file (avrdude.conf) can't be opened
I am using IDE version 1.8.19, windows 10 pro OS

P.S: previous core with optiboot bootloader also can't upload any code to new microcontroller now although i am able to upload code to any previously programmed microcontroller. This has happened before but at that time i tried to upload from another computer (windows 7) and it worked on other computer fine. Now i can't upload from any computer

It would help if you shared the actual Avrdude output.

Which version of MiniCore do you currently have installed?

[mlksahib]

Right now i don't have access to my work pc. I will share it tomorrow. (It's night time in my country)
Syntax error is related to miniCore 3 (with urboot version). I downloaded it today morning . Verbose output shows just 2 lines, 1st line is syntax error at line 421 of avrdude.conf
2nd line is avrdude.conf can't be opened

I've just hit the same problem trying to upload code to pre bootflashed 328

Here's the verbose uploaded output

Sketch uses 15180 bytes (46%) of program storage space. Maximum is 32384 bytes.

Global variables use 65 bytes (3%) of dynamic memory, leaving 1983 bytes for local variables. Maximum is 2048 bytes.

You need to install the lastest Minicore version from the boards manager. That will also install Avrdude 7.2, which is required.

Thanks for the prompt response. I had manually installed from the zip. Mike Sent from Outlook for Android<https://aka.ms/AAb9ysg>

Hi guys!
I also encountered a similar problem. I tried reinstalling the IDE, changing the avrdude.conf file, installing different versions of the IDE and MiniCore - it didn't help.
Help me please!
All this happened when trying to install the bootloader for Atmega328PB, when trying to install other microcontrollers - the situation is the same...

avrdude: error at C:\Users\parshikovsv\Documents\Arduino\hardware\MiniCore-3.0.1\avr/avrdude.conf:421:

Remove the manually installed MiniCore version and install the whole thing though the boards manager instead. The problem is that the Avrdude version that's bundled with the IDE is too old to parse the Avrdude.conf file that MiniCore uses.

[Amperogeddon]

Thanks for the quick response!
The thing is that I can’t use the board manager because I don’t have access to the Internet. Internet access is only available from a remote desktop. Is there a way to fix this error without using a board manager?
Thank you very much in advance!

[MCUdude]

You'll either have to manually replace the Avrdude executable with 7.2, or download MiniCore v2.x instead, which uses Avrdude 6.3

[Amperogeddon]

Thank you very much for your answer!
I apologize in advance for what is probably a stupid question. But how to do that?

[MCUdude]

Download the latest v2.x version here (zip file), and install it manually, as described in the README. That should hopefully just work.
