I'm just now finally able to get back to a project that I started a few months ago, and I have a couple of questions. First, though, I want to offer great thanks to Andrew and CWlinux for their SDK. That stuff really is a tremendous help.
First, DOC problems. I've spent about a day and a half getting an M810LMR up and running off a DOC, using one of CWlinux's images. Part of my problem turned out to be some flaky DOCs. Of four units I took out of a tube, two of them have turned out to have faulty sectors, from what I can tell. After futzing around, I finally came to the realization that I could not even get eraseall to work -- it would repeatedly give an MTD erase failure [1] error. It would fail at the same address every time, but that address was different for the two DOCs. The other two DOCs had no such problem. I guess that my main questions here are (a) are these DOCs toast, and (b) is this common with DOCs? These are labeled "MD-2800-D08/JAPAN0028HAK 1".
The other issue I had was with regard to the CWlinux DOC images; I don't think this is a question so much as an FYI for Andrew and maybe other newbies, I was able to work around things and I'll be moving beyond his examples soon anyway.
In cwlinux_810lmr_lite.lb, the size of the minix filesystem appears to be larger than the size of the nftl partition on the DOC [2]. This is confirmed with a error when I run the dd to write the filesystem to flash. The filesystem in the cwlinux_810lmr_mb-mii.lb image is small enough to fit, however [3]. Finally, when I use the docipl, linux.bin.gz.block, and linuxbios.block from cwlinux_810lmr_mb-mii.lb, the linux commandline gives me consoles on /dev/ttyS0 and /dev/tty0. The one on ttyS0 works fine, but the one on tty0 has carriage return issues; the virtual console on tty1 also works OK. If I use the docipl, linux.bin.gz.block, and linuxbios.block from cwlinux_810lmr_lite.lb but the minix filesystem from cwlinux_810lmr_mb-mii.lb, the command line gives me a console only on /dev/tty5 and there's a GUI splash screen. In this case, the virtual consoles, including the one on tty0, work just fine. This has worked out to be the best combination.
Thanks, --Bob

I take this back. I just noticed that, in this case, I do also get a console on /dev/ttyS0, it just isn't listed in the linux command line (cat /proc/cmdline), it comes out of inittab.
