you are right, the document from your link for s29glxxxa really has the word
programming command, but when i look at the tsop package, it seems not to be
pin compatible with type am29lv065d.
the type which amd recommended to use is not this type (s29gl064a) , it is
s29gl064m, see
http://www.amd.com/us-en/assets/content_ty...xxm_00_b3_e.pdf (http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/s29glxxxm_00_b3_e.pdf)
and look there at the command table, there is no word programming mode.
i am a little bit confused, i thought that "cfi compliant" means
"software compatible". --- Quote End --- Fischer, Looking at the link you posted Table 35 on page 113 contains the Program command. As for CFI Compliant meaning software compatible, it should, however there is no body which certifies whether a flash is CFI compliant. In the last few weeks alone I have seen a flash which claimed to be CFI compliant and indeed you could get a CFI table, however the mechanism used to get the CFI table was not that documented in the CFI spec, so it wasn't software compatible. I have also seen a flash chip which had an invalid CFI table, again not software compatible.
