In-Reply-To: <20030526161628.82FD8C6162@atlas.denx.de> Message-ID: <03May26.133048adt.7307@dragon.appliedmicro.ns.ca> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de I can't say off the top of my head. I'm using a 16 bit strataflash E28F128J3A in x8 mode, with a custom version of strataflash.c, on a custom-built Virtex-II Pro development board, with a *very* hacked down version of PPCboot that runs from about 50K of block RAM, so there are lots of places where I might have mucked things up. An 'interesting' configuration.... I hacked it to work by changing the loads code to echo a newline after the write to the flash has completed, and configuring kermit to wait until it sees a newline before it sends a new line. This works for me, so I stopped looking into the problem. -Frank. > -----Original Message----- > From: wd at denx.de [mailto:wd at denx.de] > Sent: May 26, 2003 1:16 PM > To: Frank Smith > Cc: u-boot-users at lists.sourceforge.net > Subject: Re: [U-Boot-Users] Loads function and flow control. > > > In message <03May26.125207adt.7313@dragon.appliedmicro.ns.ca> you wrote: > > > > What about in the case where you are loads-ing directly to a flash > > region?
