Hi,
i have a device with one Intel E28F128J3 (16MB NOR) and one E28640J3
(8MB NOR).
Is it possible to use both of them as one single device, especially a
partition spanning over both of them?
Currently, the first on is detected, correctly sized as 16MB, and the
second one is detected. But the total size seems to be caculated by
num_chip * size_of_first_chip, so the last 8MB alias to the first 8MB of
the second flashrom, which is not really what i want.
So, is it possible to correctly probe them? I just hardcoded the size to
0x180000, and it seems to work. But this is not really the way i want
to go.
Felix

Yes, by using the 'mtdconcat' code to combine them. You can't have the
prode code detect them both together since that requires chips to be
identical.
