Hi All, problem with SST39VF6401B70

Hi All, problem with SST39VF6401B70

[Fabio Giovagnini]

Hi All.
This is my problem
I'musing SST39VF6401B70 as a boot NOR flash; when gen_probe module 
check_cmd_set function is called detect my flash as an AMDSTD and this 
because of CFI Query struct bytes 13H and 14H  (Primary OEM commad set) is 
0002H, 0000H as an AMD standard; but CFI Query struct bytes 15H and 16H 
(Address for Primary Extended Table) is 0000H (no table); this is not conform 
to ADMSTD. How can I solve the problem? Do I have to implement a different 
driver and if yes where can I find the road map?

Thanks a lot

Have you tried using flashrom <http://www.flashrom.org/> to access your
boot NOR flash? It should work fine.
