the chip is indirectly supported. It uses the same identification as the AT25DF321, so flashrom should detect it as that. It's also the only chip model to be expected on a R500 mainboard, as far as I have seen in the schematics. > > I already tried replacing the SOIC clip and buying shorter jumper > cables. Still, the problem you are facing is most likely a hardware issue. You are not looking for something specific to the flash chip (these SPI chips are all very similar); but something that is specific to the main- board design or your flash programmer or the connection. AFAICT, you haven't mentioned yet what programmer you are using, so it's hard to guess anything. Also, how do you power the flash chip? Do you use the laptop's AC adapter? or do you try to power it with your flash programmer? In the latter case, you'll also have to expect to power half of the mainboard as the power rail is directly connected to flash chip, AFAICS (this is not recommended btw.). Keep in mind that every mainboard (that is not designed to be flashed like this) is different. When powering the flash chip via a clip, most people just succeed by luck with the right amount of power (too little and the flash chip won't work, too much and more parts of the mainboard wake up).
