Note that if flashrom is giving you an error "Couldn't open device 1a86:5512. Error: Programmer initialization failed." make sure that a jumper is placed on the pins next to the big plastic block. You can clearly see it in the video at 1:30. This changes the programmer device from UART mode to SPI mode and allows flashrom to use it. My device came without the jumper installed and I spent several hours trying to figure out why it wouldn't work, until I came across a patch for the source code of flashrom that hinted there might be a jumper necessary to switch modes.

Good information, I hope those who use CH341a will follow your discovery. Oh, I wish the chip makers would mention these in their tech manuals. Another such example is when I replaced a Compaq mobo which then had a BIOS error "Serial number not found" after a BIOS update. I had to patch BIOS with a 3rd party flash to install (tattoo as they call it) the serial number into the BIOS to bypass the irritating error screen and boot w/o issue.

@Drottninggatan2017

First you can try the autodetect function in the program. The CH341A will only deliver 3.3V to the chip. If you need 1.8V you need an adapter. 5V will require a modification of the CH341A. Other than that all SPI chips should be compatible. It is an interface, and they all use the same pins.
