Updated by Liam Flaherty over 2 years ago

S25FL128S: Appears OK. 20h command is ignored for 256-bit sectors. For other sector sizes: It appears there is a limitation in flashrom as this is for parameter sector erases only, so it is omitted entirely. The other erasers are present.
S25FL129P: Appears OK. 20h also missing for similar reasons.
S25FL256S: Mostly OK*. 20h also missing for similar reasons.
S25FS128S: Appears OK. 20h also missing for similar reasons.
{F,S,V}29C51001B: Appears OK.

  • All the 32MB chips are only declared as 16MB. I haven't been able to identify any reason for this limitation - I am still checking this detail.
