Different tools excel at specific tasks like BIOS recovery or automotive ECU tuning.
If you encounter errors while writing, use the "Unprotect" icon. Some chips have write-protection bits that must be cleared before new data can be flashed. Where to Download Releases · nofeletru/UsbAsp-flash - GitHub
AsProgrammer 2.1.0.13: The New Standard for CH341A Flashing In the world of hardware repair and BIOS modification, having reliable software is just as critical as having the right physical tools. has emerged as a cornerstone update for technicians using the popular CH341A USB programmer . While the official manufacturer tools for these budget programmers are often criticized for being buggy or limited, this third-party "fix" version has become the community's go-to for its stability and expanded chip support. What Makes Version 2.1.0.13 "New" and Essential?
The are widely used because they cost less than a cup of coffee. However, the official factory software provided by the manufacturer is notoriously outdated, buggy, and often fails to recognize modern high-capacity BIOS chips. asprogrammer 21013 new
No software is perfect. Within 24 hours of release, the community found two minor quirks:
: Beyond the standard CH341A, it supports hardware like Bus Pirate , UsbAsp, CH347, and AVRISP.
CH341DLL.DLL / libusb0.dll : Dynamic link libraries that mediate raw SPI/I2C commands from the UI straight to the CH341A hardware layer. Different tools excel at specific tasks like BIOS
: Addressed a known issue in previous 2.1.0.x builds where specific SRE (Status Register Edit) commands would fail to unlock write protection on certain Winbond chips. Getting Started with v2.1.0.13
Ideal for programming 24-series chips used in monitors, TVs, and small electronics.
, originally developed by a programmer named Alexander and expanded upon by community forks (such as the distributions and What Makes Version 2
If you work with SPI flash chips, BIOS recovery, or embedded systems, you’ve likely encountered . This free, community-driven tool has become a staple for anyone using cheap CH341A-based programmers. Unlike the clunky, ad-ridden Chinese software that usually ships with those programmers, ASProgrammer offers a clean, powerful, and constantly improving interface.
The "21013" release (often referred to as version ) isn't just a minor patch; it represents a significant overhaul aimed at making firmware dumping and writing more robust. Key improvements in this version include:
NeoProgrammer, which continues to receive updates, is built directly from the source code of AsProgrammer 2.1.0.13. It takes the stability of v2.1.0.13 and adds support for hundreds more chips, a more modern interface, and additional programmers like the CH347 and FT232H. So, if you see a download for "NeoProgrammer 2.2.0.10," you are essentially using an enhanced "new" version of the AsProgrammer 21013 core.
