Asprogrammer+21013 Jun 2026

Once you have resolved the asprogrammer+21013 error, follow these best practices to avoid seeing it again:

A clean interface that displays chip detection details, size, and SPI command configuration. Setting Up AsProgrammer 2.1.2

Documentation update for API.

: Always perform an "Unprotect" command first if the chip is write-protected. Erase : Clear the existing data on the chip. asprogrammer+21013

The of the flash chip you are trying to program?

BIOS Flashing on Windows or Linux using a CH341a MiniProgrammer

Some chips have a "Write Protect" (WP) bit enabled. Use the Unprotect icon (not the dropdown) to clear these bits before attempting to write. Once you have resolved the asprogrammer+21013 error, follow

: Handles various 24-series I2C EEPROMs and 25-series SPI Flash chips, which are standard in PC BIOS, TV firmware, and router configurations.

Install the driver (for parallel/programmer mode), not the serial COM port driver. Instant Freeze on Write Chip is completely locked or dead. Replace the physical SPI flash IC with a new one.

Verification fails at address 0x000000. Fix: Voltage droop. Power the CH21013 via an external 5V supply (not USB hub). Also, try reducing the SPI speed in ASprogrammer settings. Erase : Clear the existing data on the chip

If you’ve ever tried to recover a bricked BIOS, dump a firmware chip, or program a 25 series SPI flash, you know that hardware programmers can get expensive. Enter the unsung hero of the repair bench: paired with the CH21013 (CH341A-based) programmer.
