Frequently Asked Questions
Neoprogrammer 21 019 CH341A Full vs. Other Programmers
- Common supported chips: SPI NOR flashes (Winbond, MXIC, GigaDevice), SPI EEPROMs (25xx series), and some I2C/24Cxx if firmware supports emulation.
- Size limits: Software may limit maximum supported size; modern flashrom supports large chips, but GUI bundling might not.
- Voltage support: Ensure adapter set to the correct target VCC (3.3V for most SPI flashes on modern boards). Powering a 1.8V-only chip without level-shifting can damage it.
- In-circuit issues: Reading in-circuit may fail if other components on the board drive SPI lines or hold the bus; isolating chip (lift CS pin or desolder) may be necessary.
