This setup is correct for 2 16-bit devices in parallel, behaving like one 32-bit device. Indeed, the extra stuff done by the driver is just what's needed to make both devices work in parallel. > Jay > > -----Original Message----- > From: M.Eugenia G.Valdecasas [mailto:valdecasas@isar-tec.com] > Sent: Monday, November 10, 2003 9:01 AM > To: Gary Thomas > Cc: ecos-discuss@sources.redhat.com > Subject: Re: [ECOS] Flash detection > > > > The driver could not get your device to go into "identify" mode. > > This can happen for many reasons: > > * FLASH is write protected (the "write" signal is not allowed) > > The write signal is allowed, actually the flash enters the query mode > and read ID mode succesfully.
