AM29BDD160G external Flash programming

[maboulais]

Hi all,

I am trying to implement flash sector persistent protection on the
AM29BDD160G flash chip on the MPC566EVB board. I have a working driver
which can erase and program correctly. My goal is to only use the
persistent protection.

Has anyone managed to implement the "PPB Status", "PPB Program"
and "ALL PPB Erase" commands ? I can't seem to find any drivers
outthere for that chip which implements protection. (ecos, ucLinux..)

One of the issues I am having is that the "PPB Status" command
indicates that a given sector's PPB bit is set while I can program and
erase as I like...
