Flash Check Error Address 0h Ezp2019 ((new)) -

The error "flash check error address 0h" on an EZP2019 programmer typically indicates a communication failure between the software and the physical memory chip at the very first memory address (0h). This often happens when the programmer cannot read or write to the chip, usually due to physical connection issues, incorrect software settings, or a locked/damaged chip. Common Causes and Solutions

What finally worked: They noticed that the laptop’s CMOS battery was still connected (a CR2032 providing 3V). Even with the main battery removed, the CMOS battery was feeding VCC to the flash chip through the chipset’s standby rail. After removing the CMOS battery, the error disappeared, and the chip was read successfully.

  1. Verify Power Supply and Connections: Double-check the power supply and connections to ensure they are adequate and secure.
  2. Update EZP2019 Firmware and Software: Ensure that both the EZP2019 firmware and software are up-to-date.
  3. Check Device Support and Selection: Confirm that the device is supported and correctly selected in the software.
  4. Try a Different Device or Test the Device: Test the device on a different programmer or try programming a different device to isolate the issue.
  5. Reset EZP2019 Settings: Reset the EZP2019 settings to their default values.
  6. Clean and Reinstall Software and Drivers: Reinstall the EZP2019 software and drivers, ensuring a clean installation.
  1. Clean and reseat the clip – three times.
  2. Kill all power to the target board (including CMOS).
  3. Test with a bare chip in the ZIF socket to verify the programmer works.
