In flashchip.c, there is (just an example),
/* Vendor Chip ... Page size (B) ... */
...
{"SST", "SST25VF040B", ... 256, ... },
How to find out the number 256? I have read through the datasheet of
that chip, which mentioned 4K sector, 32K and 64K blocks, but no
"page". There is neither an operation which needs an address with
value 0 in the least significant 8 bits.
Or, the number does not come out of a datasheet?
Thanks,
yu ning
