Older versions sometimes failed to read/write chips larger than 16 MB (128 Mbit) due to improper handling of 4-byte addressing. Version 21.0.13 corrects this, ensuring full access to 32 MB and 64 MB SPI flashes.

This version introduced several notable changes compared to older releases (like v1.41):

Originally developed by a developer known as Tifa, AsProgrammer serves as a massive upgrade over the notoriously buggy default software that ships with cheap Chinese hardware programmers. It acts as the bridge between your Windows PC and the external chip you are trying to manipulate.

| Issue | Solution | |-------|----------| | Programmer not detected | Reinstall the CH341A driver. Try a different USB port (USB 2.0 preferred). | | Chip not in list | Manually select a compatible chip family (e.g., MX25Lxxxx). Or use "Generic SPI" mode. | | Verification fails after write | Reduce SPI speed in Settings → Advanced → "Read/write delay" set to 10 µs. | | App crashes on launch | Delete the settings.ini file from the ASProgrammer folder and restart. |

Run CH341PAR.EXE to ensure your computer recognizes the programmer. Run AsProgrammer

The original author (Radim “MCUmike” Kábrt) hosts the project on GitHub. However, note that the main repository sometimes lags. The most active and trusted distribution for version 21.0.13 is:

Before you download from any third-party site, especially Chinese ones, it's crucial to run a virus scan on any downloaded file. Many of these sites bundle software with unwanted adware or toolbars.

He almost laughed. It read the entire chip in 12 seconds—three seconds faster than the old version. He saved the corrupted BIOS to bricked_dump.bin . Then he downloaded a clean BIOS from the manufacturer's FTP site (another hour of tedious searching). He loaded the clean file into ASProgrammer 21.013, clicked "Program," and watched the blocks fill in like a digital paint-by-number. This version introduced several notable changes compared to

Optimized communication speeds, making backups and flashing quicker.

He sighed. The old version didn't recognize newer silicon revisions. The chip was too new, the protocol timing slightly off. He was holding a brick.
