programmer hardware to flash BIOS chips, recover bricked motherboards, or modify firmware on various electronics. Win-Raid Forum Overview of AsProgrammer v2.1.0.13 This version is widely cited in technical forums (such as ) as a stable, "fixed" release. Functionality

Check these:

Beyond just the common CH341A , this version supports various programmers including UsbAsp , Arduino , FT232H , and CH347 .

In the context of hardware flashing, numbers like "21013" typically point to one of three things:

In the world of low-cost hardware hacking, BIOS recovery, and EEPROM flashing, few tools have achieved the cult status of the series programmers. For less than the price of a pizza, these tiny black or blue USB dongles allow you to read, write, and erase BIOS chips, flash memory, and EEPROMs. However, the default software that ships with these programmers is often clunky, outdated, and unstable.

The string functions as a unique handle or "tag" used across various technical and social ecosystems. While not a high-profile entity, its footprint is primarily found in: Developer Forums:

Once conquered, the CH341A running ASProgrammer is an incredibly reliable tool. You will be able to flash Coreboot, repair corrupted UEFI BIOS, and dump EEPROMs from vintage electronics without seeing that dreaded 21013 error again.

Official sources for the most recent software builds and firmware updates.

Use the "Status Register" option to unlock (unlock block protection) the chip before trying to erase or write.

The hardcore hardware community discovered a permanent fix for the 21013 error: on the MISO line (pin 2 of the CH341A chip to pin 9 - VCC). The CH341A’s internal pull-ups are weak. When flashing at default speeds, the MISO line floats, leading to the 21013 timeout. Adding an external 10k resistor solves this permanently.

ASProgrammer is a lightweight, powerful flashing utility written by npro. It was designed to replace the archaic Chinese software (often named CH341A.exe or NeoProgrammer ) that typically comes with CH341A-based programmers.

Bug fix for crashing on startup.
