While Windows is the primary target, ASProgrammer 21.013 runs excellently under Wine (Linux) or CrossOver (macOS). Here’s the quick guide:
Many users report that 21.013 has fewer USB dropouts on Linux than newer versions.
Even with the latest version, you might encounter hiccups:
| Problem | Likely Solution |
|---------|------------------|
| “Programmer not found” | Reinstall CH341A drivers; disable Windows driver signature enforcement (for older drivers) |
| Verification fails at 50% | Bad contact with chip clip – clean pins or reduce SPI speed via Settings → Slow mode |
| Chip ID all zeros (0xFFFFFF) | Wrong pinout; check your wiring. For SOIC-8, ensure pin 1 (CS) matches |
| Program crashes on erase | Uninstall previous version first; delete old ASProgrammer.ini config file |
For advanced users scripting batch operations, the --verify flag no longer false-reports mismatches on padded data.
