Bug fix for crashing on startup.
Use a digital multimeter to verify the voltage output across the logic pins. asprogrammer+21013
If you are building the software from source—either using the master nofeletru branch or customizing the therealdreg dregmod variant—follow this exact sequence to compile without errors:
Many budget CH341A hardware programmers (specifically the infamous "Black Edition" boards) feature a design flaw that outputs 5V on the data pins despite routing 3.3V to the power pin. Because most SPI NOR flash memory runs strictly at 3.3V or lower, long-term exposure to 5V logic signals can degrade or destroy the chip.
