Using CH341A Mini Programmer on Armbian

[Jordan1x]

Hi all,

I’m running Armbian 24.5 (Ubuntu Jammy CLI) on an Orange Pi 3 LTS with kernel 6.6.y, trying to use a CH341A Mini Programmer to flash an SPI EEPROM chip. But I’m stuck,  the programmer isn’t detecting the chip at all.

 

Connected the module to the chip using the correct pins (CS, MOSI, MISO, CLK). Powered the chip at 3.3V to match Armbian’s logic level. Used flashrom on Armbian (via terminal) to detect the chip, but it returns “no device” or similar errors. Tried different USB ports, different cables , same result.

 

Do I need to match some specific SPI mode or speed for Armbian or for specific EEPROMs? Is there an issue with voltage levels or pull-up / pull-down resistors that often catches beginners? Any recommended OS commands/logs to check so I can see what’s going wrong (e.g. permissions, USB detection, lsusb output)?

 

Thanks in advance for your help!
