#7: Using serprog to flash a winbond W25Q16 ----------------------------------+------------------------------- Reporter: anonymous | Owner: hailfinger Type: defect | Status: new Priority: major | Milestone: flashrom 0.9.2 Component: flashrom | Version: 0.9.0 Keywords: Single byte read | Dependencies: Patch Status: there is no patch | ----------------------------------+------------------------------- I am using an arduino Uno to flash a winbond W25Q16, and I'm getting an error: Single byte read not supported. I am using Flashrom v0.9.4-r1394, linux 3.0.0-12-generic (i686), built w/ libpci 3.1.7, Gcc 4.6.1. On an Ubuntu 11.10 32bit release. I get the error when I use:
$ flashrom -p serprog:dev=/dev/ttyACM0:2000000 -w /home/jpl/716.rom
or any command like reading the bios. Just looking for some help, I couldn't find anything when searching. Thanks. Brandon

Oh I forgot to mention, I'm using some header pins on the motherboard to hook up to the arduino, the pins I have plugged in are: Vcc > 3.3v from the arduino, Gnd > Gnd, Miso > Pin12, Mosi > Pin11, Clock > Pin13, CS > Pin10. Those are the only connections coming off the Header pins. So to list what I have hooked up: Miso Mosi VCC Gnd Clock CS
Am I missing something on the chip that I need to plug in?

Hi Brandon,
this looks like a bug in either the Arduino serprog firmware or in the serprog driver in flashrom. Can you please retry with the latest flashrom version and send a mail to the flashrom@ flashrom.org mailing list?
Sorry for the long delay before you got an answer. Trac shouldn't have allowed creating new tickets at all because we track all bugs on our mailing list nowadays.
