Hi David, A hot tip would be to configure either syslog to log to a logserver or at least mount a tmpfs filesystem on /var/log. Running a syslog could wear out the flash quite quickly, especially during the development phases...
While you are at it, mount tmpfs's on /tmp and /var as well. I believe JFFS2 suits very well in a embedded device, the system just need to be configured for a such, since a "standard" linux installation are more outlined for server/desktop usage ;-) Regards, Per -----Original Message----- From: David Jander <[EMAIL PROTECTED]> To: "'linuxppc-embedded at ozlabs.org'" <linuxppc-embedded at ozlabs.org> Date: Thu, 16 Jun 2005 14:56:43 +0200 Subject: jffs2 freezing in gc for long time... > > Hi list, > > I have the following situation: > > CPU: MPC852T-100MHz > Flash: 32Mbyte mirror-bit, 15Mbyte jffs2 partition rw-mouted > Kernel: 2.4.25 (linuxppc_2_4_devel CVS from denx from a month ago or > so, with > custom patches not concerning MTD at all).
