I'm looking for a NOR-Flash for a RM9200-based board, and i thought maybe some of you could give some hints or experiences. Basically it should be 128MByte size, with larger drop-in replacements as a favorable option. As with all RM9200 parallel flash, must have CFI, and must be available in a non-BGA package. For a first guess, i found the Spansion S29G128P - any experiences with that one? How well is it supported by the kernel, or are there any obvious caveats that i overlooked now? Greetz, Joe => The AT91RM9200 has 26 Adress pins (A0-A5) but A24 is nol available. (See Errata) This gives you a 16 MB linear adressrange. Since A25 is available you can have 2 x 16 MB spaces with a 16 MB hole in between. However, I suspect that you only plan 128 Mbit and not 128 MByte and then this is not a problem If you are starting a design now,You should perhaps consider the AT91SAM9260 or the AT91SAMG20 -- Sepp "ZaP" Holzmayr please reply to: zentrale.at.work at gmail.com "Never underestimate the bandwidth of a freight train full of DAT tapes. Only the round-trip is a little suboptimal." _______________________________________________ buildroot mailing list buildroot at uclibc.org http://busybox.net/mailman/listinfo/buildroot -------------- next part -------------- A non-text attachment was scrubbed...
