Keith thanks Yes can u send id ? Regards doron -----Original Message-----From: Keith Lugsden [mailto:keith@xxxxxxxxxxxx] Sent: Wednesday, April 16, 2008 11:06 AMTo: Doron SandroyCc: Bill Gatliff; דורון; linux-arm@xxxxxxxxxxxxxxxxxxxxxxxxxxxxx: RE: add SPI support I have got kernel 2.6.25-rc6 working on a Compulab cm-x270. It sits inNOR flash while the root filesystem is in NAND. First, you need to mount a root filesystem using NFS, then you can usethe MTD utility "flash_eraseall -j" to set the flash the JFFS2 eraseblocks, then do "mount -t jffs mtd1 /mnt/flash". At this point, you cancopy the files from the NFS filesystem to the JFFS2 filesystem. If yourfilesystem contains a lot of files, you can compress them first using"tar -czf out.tar files". Booting from the ARMmonitor then works with:> bootos "root=/dev/mtdblock1 rootfstype=jffs2 console=ttyS0,38400" In this way, you never need to use the Compulab flash driver. Moreover,you can do all your development on the NFS filesystem, and only copy tothe JFFS2 filesystem when finished. If you need further help, I can post my kernel config and/or my NFSsetup. -- Keith On Wed, 2008-04-16 at 09:52 +0200, Doron Sandroy wrote:> Thekes > I agree but,> There is no support for copulab card for kernel 2.6.25-rc> The flash driver for ext3 is object there for I need the support from copulab.> And The only support is for 2.6.12.> r.g.> Doron Sandroy> > -----Original Message-----> From: linux-arm-bounces@xxxxxxxxxxxxxxxxxxxxxx [mailto:linux-arm-bounces@xxxxxxxxxxxxxxxxxxxxxx] On Behalf Of Bill Gatliff> Sent: Tuesday, April 15, 2008 9:16 PM> To: דורון> Cc: linux-arm@xxxxxxxxxxxxxxxxxxxxxx> Subject: Re: add SPI support> <דורון wrote:> > I need to add standard SPI support to kernel 2.6.12 for pxa255 > >> > Where I find source code example, howto and install help.> > > > Probably be easier to work with the latest kernel, 2.6.25-rc*.> > > b.g.> > -- > Bill Gatliff> bgat@xxxxxxxxxxxxxxx> > > > -------------------------------------------------------------------> List admin: http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm> FAQ: http://www.arm.linux.org.uk/mailinglists/faq.php> Etiquette: http://www.arm.linux.org.uk/mailinglists/etiquette.php> > > > ************************************************************************************> This footnote confirms that this email message has been scanned by> PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses.> ************************************************************************************> > > > > > > > ************************************************************************************> This footnote confirms that this email message has been scanned by> PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses.> ************************************************************************************> > > > > -------------------------------------------------------------------> List admin: http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm> FAQ: http://www.arm.linux.org.uk/mailinglists/faq.php> Etiquette: http://www.arm.linux.org.uk/mailinglists/etiquette.php ************************************************************************************This footnote confirms that this email message has been scanned byPineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses.************************************************************************************ ************************************************************************************This footnote confirms that this email message has been scanned byPineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses.************************************************************************************ -------------------------------------------------------------------List admin: http://lists.arm.linux.org.uk/mailman/listinfo/linux-armFAQ: http://www.arm.linux.org.uk/mailinglists/faq.phpEtiquette: http://www.arm.linux.org.uk/mailinglists/etiquette.php
