Asprogrammer 2.1.0.13 [updated]
This often happens if the "Erase" step was skipped. You cannot write new data over old data without a full erase.
While is a stable legacy version, many technicians have switched to newer solutions:
When paired with a 1.8V adapter, it can program low-voltage chips common in modern laptops, such as the Winbond 25Q128FW.
: The software writes the new firmware and then performs a bit-by-bit comparison (verification) to ensure the data on the chip perfectly matches the source file. Technical Impact and Safety Asprogrammer 2.1.0.13
Usually caused by a poor connection with the SOP8 clip. Ensure the pins are clean and the clip is seated firmly.
If you are struggling with the software itself, newer or alternative versions are available:
is a well-known derivative of AsProgrammer 2.1.0.13. The developer of NeoProgrammer took version 2.1.0.13 as a base and made several modifications. In real-world tests, users reported that NeoProgrammer offered more user-friendly features and significantly faster read/write speeds. For example, reading and verifying a 16MB BIOS from an ASUS B85-PLUS motherboard took 2 minutes and 55 seconds with AsProgrammer, but only 2 minutes and 29 seconds with NeoProgrammer. This often happens if the "Erase" step was skipped
: This specific version is often cited in the community as a "fix" version, stabilized by independent developers to resolve common verification errors—such as the dreaded "content mismatch" that plagued users of the standard CH341A software.
: When using version 2.1.0.13, ensure you have the CH341PAR driver installed rather than the "Serial" (CH341SER) driver to ensure the software recognizes the hardware in "Parallel/Programmer" mode.
: For SPI flash chips (25 series), the "Auto Detect" button can identify the chip ID and signature automatically, saving you from hunting through datasheets. : The software writes the new firmware and
The software acts as a bridge between a computer and external hardware programmers like the affordable , UsbAsp , or Arduino -based setups. Its primary utility lies in:
The software includes detailed pinout diagrams for various EEPROM types, aiding in correct chip connection. Supported Programmers
Version 2.1.0.13 represents a stable milestone in the software’s lifecycle, particularly noted for its compatibility with modern 25-series SPI Flash 24-series I2C EEPROM
: Go to the Hardware menu and select your specific device (e.g., CH341a).
Whether you are unbricking a PC motherboard, extracting firmware from a Wi-Fi router for security analysis, or flashing a graphics card VBIOS, ASProgrammer 2.1.0.13 provides an efficient interface for EEPROM and Flash NOR manipulation. Key Capabilities and Protocol Support
