RE: [leaf-user] Compact Flash Boot Failure
Hi! IMHO using dd to backup and restore CF's is a very very bad idea. Specially if these CF are from different manufacturers, often with different CHS settings. I never had a problem with CF, as I syslinux them and copy the LRP's by hand. The last 3 or 4 updates I did on my router were even done with a CF USB adapter from Windoze... Hope this helps a bit.

Not having all the hardware available that I did when I first built the boxes was a problem... specifically, no Linux laptop with PCMCIA. Finally pulled a Knoppix ISO and got an XP laptop going off the CD-ROM drive (note to anyone that cares, an Inspiron 1150 doesn't like the default Knoppix boot. Specifying the 2.6 kernel at boot solves that)! What I did: copied all the packages off the CF for safe keeping (had a copy from some months ago, but wasn't sure what changes might have been made along the way). syslinux -s /dev/hde1 Put it back in the box. Booted to syslinux (with the BIOS set manually to what I *thought* was the closest settings) but not beyond... loading linux, loading init, then nothing. Copied the packages and config file back onto the CF, overwriting what was there. Back in the router. Boot was fine this time. During the startup screens I see the CF detected by Linux as CHS 244/4/32 (16MB Lexar). I was set manually to 251/2/32 which works for the 8MB version of this card. The image on the 16 was dd'd from an 8MB image, so this might (?) be why it worked... If I'm honest, I'll 'fess up and admit I forgot to reset the CHS after messing with an 8MB card! ;-) Manually changed the BIOS to 244/4/32 and rebooted several times. No issues that I can see. Now, when the BIOS autodetected the card originally, it came up with Pre =-1, LZ=244. These parameters are blank when manually configured. Do they make any difference to the CF? Oh yeah, I also put the whole mess into a duplicate machine (same model) to test the power supply theory. New CF adapter too. Thanks to all who made suggestions!

Re: [leaf-user] Compact Flash Boot Failure
Hi, The PCMCIA flash technology was something I used before CF was available. I have some PCMCIA to IDE adapters that I bought from Addtron, and I bought a bunch of 32M PCMCIA cards. The solution was fairly expensive at about $200 per system (compare that to a $20 adapter and a $10 CF card today), but at the time it was more about the reliability in my router than anything else. The only reason that I mentioned it was that I have systems that have been in place for 5 years and have never had a problem. I've had some of them running since when Dave and the gang were starting out with LRP. Thanks, Jim wing newton wrote: Jim, How did you get it booted from pcmcia flash ? Thanks.

Hi Brock, Has anyone had a problem like this? I'd like to know if the box could be the problem before I take the time to replace this CF yet again. The unit is in a remote location and is fairly mission-critical. I can't have this happen so regularly. This has happened to me. I am using LEAF Bering-uClibC with bgpd for 4 solid-state routers. Unfortunately one of my routers seems to regularly chew up its CF card. I've switched the types of cards around in the system to no effect. My solution so far has been to back up the drive regularly and not reboot, not exactly a nice solution. I have not had the time to look into this matter properly, but a few ideas that have come to mind are: - Measure the voltage being given to the CF/IDE card. - Measure the voltage the CF/IDE card is giving the CF. - Check the cylinder count etc. on your IDE card, if possible. Rumor has it incorrect IDE setup can lead to this problem. - Replace the CF/IDE and CF card. I have used netcat and disk dump to good effect in backing up / restoring my images. Try: (on destination) : nc -l -p port | dd of=/dev/hda (on original server) : dd if=/dev/hda | nc addr of other machine port as above Regards, P --- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.

Yes. This is what I do. Log to RAM and only back it up you you need to to do a postmortem. I would not recommend running from CF. The unique thing about LEAF is that boot media is boot media, and the running system functions the same no matter what type of bitholder you use to get the stuff into RAM.

Sorry, I didn't mean no logging. I was just warning you not consider compact flash an acceptable logging device. Many people are not happy with ramdisk capacity. Some log to a remote syslogd.

I curious why there seems to be so little interest in Compact Flash. There's actually quite a bit of interest in CF, and other forms of flash media. I suspect a couple issues are responsible for the substantially larger number of posts regarding CD-ROMs: 1) Like it or not, most folks first LEAF system is built from spare parts lying around, or perhaps an existing system pushed into temporary use as a trial LEAF system. In this environment, standard PC devices (like a floppy disk or CD-ROM boot) are the least path of resistance. 2) Due at least partly to the above, I think most help it's not working type posts come from new users who are following the path of least resistance, and booting with a floppy or CD. 3) It's not really that hard to migrate from a floppy or CD version of LEAF to running off a HDD, CF card, flash based IDE module, or pretty much anything else that looks like a HDD to linux, so I think there are a fair number of users running with flash that we simply never hear from on the list... 4) There are occasional flurries of posts regarding flash storage, especially with regards to write-protectable flash devices (which are hard to come by)...the latest have all been on the LEAF-developer list...perhaps you missed them?

Re: [Leaf-user] Compact Flash vs CD Rom
My personal response to this question is I'm Cheap. My mobo doesn't support booting of CD Rom and the only spare CD Rom drive I have doesn't read CDRs (altho obtaining one of these freely wouldn't be too much trouble) - replacing those was outta the question. I installed DCD on HD - cause I had one of those lying around and even worked out the boot up process and everything (I'm not much of a scripter). Definitely, assuming a Compact Flash adapter would work with my Mobo (which should be the case), your approach would have been easier. But then, I'm Cheap, and its more fun having a router that smokes a Linksys and some Ciscos, that didn't cost me a dime, works perfectly and expanded my knowledge base.

Re: [Leaf-user] Compact Flash vs CD Rom
Charles, We discussed these chards (PQI CF WP) on the devel list a couple of months ago. From what we were able to determine the write protect function will not work in true IDE mode. Sorry. ref. search string pqi http://www.mail-archive.com/leaf-devel%40lists.sourceforge.net/ My father and I are still working on the ATA-Disk Module from SST.

Now that's commitment to the embedded marketplace :) The manufacture link for this device is: http://www.pqi.com.tw/eng/ourproduct/ourproduct.htm Note: they're not advertising the WP version any more. I suspect it's due to compatibility problems that were noted in our discussion on the devel list. They have a new secure DOM out. It may be of use. http://www.pqi.com.tw/eng/ourproduct/sdom.htm -- Mike Noyes [EMAIL PROTECTED] http://sourceforge.net/users/mhnoyes/ http://leaf-project.org/ ___ Leaf-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user
Re: [Leaf-user] Compact Flash vs CD Rom
I've noticed a zillion posts to this list corncerning LEAF on CD-ROM. I curious why there seems to be so little interest in Compact Flash. There's actually quite a bit of interest in CF, and other forms of flash media. I suspect a couple issues are responsible for the substantially larger number of posts regarding CD-ROMs: 1) Like it or not, most folks first LEAF system is built from spare parts lying around, or perhaps an existing system pushed into temporary use as a trial LEAF system. In this environment, standard PC devices (like a floppy disk or CD-ROM boot) are the least path of resistance. 2) Due at least partly to the above, I think most help it's not working type posts come from new users who are following the path of least resistance, and booting with a floppy or CD. 3) It's not really that hard to migrate from a floppy or CD version of LEAF to running off a HDD, CF card, flash based IDE module, or pretty much anything else that looks like a HDD to linux, so I think there are a fair number of users running with flash that we simply never hear from on the list... 4) There are occasional flurries of posts regarding flash storage, especially with regards to write-protectable flash devices (which are hard to come by)...the latest have all been on the LEAF-developer list...perhaps you missed them?
