Hello Andreas, 1) Yes there are some similar names, but the name by itself doesn't mean much - whether the chip is supported or not depends on all the other properties in the chip definition. To answer the question we need a datasheet for your chip. I could find the datasheet for W25Q128JV (like yours but without "50" at the end), do you think it's yours?
2) The datasheet for W25Q128JV which I look at (but don't know if it's yours) describes models that identify as 0x4018 and 0x7018 , and we have definitions with these IDs in our flashchips. In general, if your model returns one of supported IDs (which are all in include/flashchips.h) , then the chip gets identified. 3) It happens sometimes that new models are released with the same IDs as previous models. It is possible that the chip will get identified by ID but match a different definition (and may still work. or may not). Again, datasheet would help recognise that. 4) If your chip supports SFDP protocol (which is common now) you can do read/write/erase operations via SFDP detection, for this you can add `-c "SFDP-capable chip"` to the command line. Then flashrom will only talk to the chip with SFDP and won't look at existing model definitions. Note this won't support write-protect commands (but maybe you don't need them) As a summary, if we can look at the datasheet it would be great. If not, you can try probing (only probing first) and see if the chip is detected. You can share the verbose logs from probing (fto be verbose add -V or -VV to the command line). If you don't need write-protect commands you can also try probing with `-c "SFDP-capable chip"`. Hope this helps, tell us how it goes!
