The AVR Assembler (avrasm2) may be used with MPLAB® X IDE or Microchip Studio for 8-bit assembly-code projects and solutions. The assembler is bundled with Microchip Studio. (Older version may be found with Atmel Studio.)
Avrasm2.exe problems are generally seen during Third-Party Application program launch, and typically caused by executable file corruption, or in some cases if the file has been accidentally or maliciously removed by malware. Ordinarily, installing a new version of the EXE file will repair the problem creating the error. As a last measure, we recommend using a registry cleaner to repair any invalid avrasm2.exe, EXE file extension, and other file path references which could be causing the error message.
Once the file is successfully placed in the right location on you hard drive, these avrasm2.exe issues should disappear. Running a quick verification test is highly recommend. Try re-opening Third-Party Application to see if the error message still appears.
Usually avrasm2.exe errors with Third-Party Application happen during startup or shutdown, while avrasm2.exe related programs are running, or rarely during the OS update sequence. It's important to note when avrasm2.exe issues happen, as it helps troubleshoot Third-Party Application problems (and report to Windows Software Developer).
When the 'Settings' page is being loaded, the plugin scans for every .inc file in the plugin directory (%USERPROFILE%\.vscode\extensions\smoluks.avrasmcompiler-0.0.14\inc). You can delete unused .inc files to speed up the loading process, or add additional files if needed. You can take .inc from Atmel Studio (C:\Program Files (x86)\Atmel\Studio\7.0\packs\atmel\[family]\[version]\avrasm\inc).
To compile my program, I used avra, which should be compatible with Atmel's avrasm (Windows-only). The recommendation for Linux, gavrasm, doesn't provide Mac OS X binaries (and it's written in Pascal, which made me reluctant to attempt to compile it). I had to copy the ATtiny45 board definition file from AVR Studio on Windows.
After the above version of Microchip Studio is replaced by a newer version, it will be available from the Downloads Archive for AVR and SAM:www.microchip.com/en-us/development-tools-tools-and-software/avr-and-sam-downloads-archive
This information is available for the avr-gcc compiler in an application note called Atmel AT1886: Mixing Assembly and C with AVRGCC available from:ww1.microchip.com/downloads/en/appnotes/doc42055.pdf
A driver installation tool called Zadig is used to install a driver for the USBasp on a Windows computer. Go to zadig.akeo.ie and download the Zadig executable file by clicking the link under the Download heading on the web page.
Documentation in the form of a PDF file for avrdude that contains more information on using avrdude can be found at download.savannah.gnu.org/releases/avrdude/ which contains PDF files for each version of avrdude. 2b1af7f3a8
