Hi Nod, Werner,
Please provide your production information. Werner can't decide the
NAND/NOR flash partition map here. Thanks.
According GTA02 product specification, we have backup and maintenance
features. Jserv will also request one partition flash that has erasing
protection here. There is a another design issue that NOR flash is
booting uboot and kernel. Or we still use current state that is booting
from NAND flash.
Regards,
willie

If it is really needed for the data to stay in the flash, I guess since
we change the partitioning to support NOR it's okay to change it at the
same time to add a partition... what do you think Werner?
Yes, what we would need to decide this properly is a list (from Nod ?)
of things that have to go to this partition (or whatever it shall be).
This list has to detail:
- what is it ? E.g., serial number.
- who accesses it ? E.g., set and read by DM2 (= kernel)
- how big is it, roughly ? E.g., a few bytes.
- how long does it have to be on the device ? E.g., forever.
If we can't get this list, then a "worst-case" solution would be to
just create a new NAND partition, along with all the other partition
changes. (I suspect that's what production has in mind anyway, i.e.,
basically what we've done for HXD8.)
Cheers, Werner
