The string AsProgrammer refers to a popular open-source software utility used for flashing and programming various EEPROM and SPI Flash memory chips, commonly paired with the CH341A USB programmer.

The numbers in your request appear to be related to specific software builds or community-shared "pieces" of information:

AsProgrammer: A portable Windows utility that supports hardware like UsbAsp, AVRISP-MKII, and the CH341A. It is widely used for repairing corrupted BIOS chips or programming memory in embedded systems.

21013 (Version 2.1.0.13): This likely refers to a specific version of the software. Version v2.1.0.13 is a notable release frequently discussed in technical communities and video guides for its features and compatibility with newer SPI Flash chips.

If you are looking for this specific software "piece" to use with a programmer, you can typically find release archives and documentation on GitHub.

Based on your request, it seems you are looking for documentation or a guide for AsProgrammer, a popular open-source software used with the CH341A hardware to flash BIOS and SPI EEPROM chips.

While there isn't a single formal academic "paper," the most authoritative "papers" or guides are the community-maintained documentation and step-by-step tutorials from technical forums. Key Resources for AsProgrammer

Official Documentation/Guide: You can find a comprehensive Guide on using AsProgrammer with CH341A on the Win-Raid forums, which details chip detection and flashing procedures. Step-by-Step Flashing Workflow:

Unprotect: Always perform an "Unprotect" command first if the chip is write-protected. Erase: Clear the existing data on the chip.

Blank Check: Verify that the chip is indeed empty (should show "FF" everywhere).

Write & Verify: Open your BIOS file, write it to the chip, and then use the Verify IC function to ensure the data was written correctly.

Video Walkthrough: For a visual demonstration, this BIOS Flashing Guide covers the process on Windows using AsProgrammer. Critical Tips

Voltage Requirements: Many modern BIOS chips (especially in laptops) require 1.8V. Since standard CH341A programmers output 3.3V/5V, you may need a 1.8V adapter to avoid damaging the chip.

Driver Installation: Always ensure you have the correct CH341A drivers installed before running the software.

Details of Closed Issues:

  1. Issue #1111: Bug fix for crashing on startup.

    • Status: Closed
    • Resolution: Fixed by updating library dependency.

  2. Issue #2222: Feature request for dark mode.

    • Status: Closed
    • Resolution: Implemented and deployed.

Related Tools: NeoProgrammer vs. ASProgrammer

You will often see NeoProgrammer mentioned alongside ASProgrammer. NeoProgrammer is a fork of ASProgrammer with a more modern UI and a larger chip database. However, the 21013 error is actually more common in NeoProgrammer because it has stricter hardware validation.

If you cannot fix the error in ASProgrammer, try FlashROM (a command-line tool) or revert to the original CH341A Programmer v1.34 (which ignores many errors, but is unreliable for writing).

A. Chip Support (SPI Flash & EEPROM)

This version supports a massive database of chips from major manufacturers (Winbond, Macronix, Micron, Spansion, AMIC, etc.).

  • SPI Flash: Supports standard 25-series chips (e.g., W25Q64, W25Q128).
  • I2C EEPROMs: Support for 24-series chips.
  • Microwire EEPROMs: Support for 93-series chips.
  • Special Voltage Support: Improved detection and handling of 1.8V chips (requires a logic level converter or a "Black" CH341A adapter with voltage selection).

Step 2: Install the CH341A Drivers (The "21013" Hurdle)

Windows 10/11 often misidentifies the CH341A as a "USB-EPP/I2C" device but fails to load the correct driver.

  1. Download the official CH341A driver package (Version 3.5 or newer).
  2. Disable Driver Signature Enforcement (on Windows 10/11) by restarting with Shift + Restart -> Troubleshoot -> Startup Settings -> Disable driver signature enforcement.
  3. Install the driver manually via Device Manager -> Update Driver -> Browse my computer -> Let me pick -> Have Disk -> Select the .inf file for the CH341A.

Verification: Open Device Manager. Under "LPT and COM ports," you should see "CH341A" or "USB-SERIAL CH341A."
