| 01:48.24 | mzb | ze: from memory, the last time I looked at the angstrom image it was designed to run from flash ... not completely sure about that |
| 01:49.04 | mzb | pretty sure it didn't have pcmcia/etc built into the kernel, which meant it couldn't boot from CF ... .or maybe it was that it didn't have SD/MMC support |
| 01:49.11 | mzb | it was one/or both |
| 01:49.21 | mzb | end result was that it wouldn't boot from a card |
| 01:50.20 | ze | hmm well its install instructions for h2200 has you install it to a cf or sd and optionally put the root on internal flash |
| 01:51.14 | ze | and that narcissus image generator has options for the image type of jffs for flash or ext2 or tar.gz etc |
| 01:51.29 | mzb | uhuh |
| 01:51.44 | mzb | and back in the day this is why I wrote ramdiskrescue |
| 01:52.10 | mzb | check the config of the kernel before you try something that may/maynot work |
| 01:52.43 | ze | building the kernel in it's oe dev environment, though, has generated a haret config :p |
| 01:52.46 | mzb | in theory, you can run ppc + haret + ramdiskrescue, and rr will unpack and setup that download for you |
| 01:53.00 | ze | hmm |
| 01:53.32 | mzb | xBUT the developer that helped them setup that system initially was involved in my project |
| 01:53.41 | ze | yeah i glanced through the modules it built to make sure ext2 was builtin instead of one, but didn't think of pcmcia |
| 01:53.55 | mzb | and mmcblk ? |
| 01:54.02 | mzb | mmc |
| 01:54.11 | mzb | ide ? |
| 01:54.18 | ze | yeah, i'll be sure to check thoses |
| 01:54.26 | mzb | all sorts of things needed |
| 01:54.46 | mzb | I think they were doing some trickery with loopbacks at one point |
| 01:55.07 | ze | hmm |
| 01:56.08 | ze | well i dunno why i shouldn't be able to include the right drivers in the kernel i build to make it be able to mount its root from cf/sd |
| 01:56.22 | ze | if it doesn't by default, which i suspect it does |
| 01:57.26 | mzb | tbh, putting it on SD makes much more sense as there isn't (or wasn't) open-source support for SDIO |
| 01:57.46 | mzb | ie: CF can be used for network/camera/storage/etc, but SD can only be used for storage |
| 01:58.12 | ze | hmm |
| 01:58.24 | ze | but i already found the linux drivers for the cheapest sdio wifi cards on ebay |
| 01:58.26 | ze | :p |
| 01:59.38 | ze | and yeah no pcmcia (except some nic drivers), ide, or mmc anything among the modules for its kernel build |
| 02:00.02 | ze | so i'll assume they're built-in rather than excluded entirely |
| 02:00.04 | ze | heh |
| 02:01.39 | ze | i found the angstrom channel, maybe someone there can help fill in the gaps for building an image from their oe build environment |
| 02:26.10 | mzb | check the config, don't make assumptions |
| 02:27.15 | mzb | not sure about current situation, but you used to need them statically compiled in as they couldn't be run with initrd containing the modules (for whatever reason) ... that could have just been a convention, not sure |
| 02:45.53 | ze | i've never used initrd type junk.. always just compiled my own kernels and included what they required :p |
| 02:46.17 | ze | but i'm of the apparently bizarre opinion that a user should be competent |
| 02:46.48 | ze | while apparently the rest of the world is eager to go out of its way to believe otherwise |
| 02:46.50 | ze | :p |
| 04:01.45 | mzb | a monolithic kernel is not always the best answer |
| 04:02.46 | mzb | particularly on a machine with very limited memory and many (possible) devices |
| 04:45.06 | ze | i don't mean everything it might possibly use, just everything it strictly requires |
| 04:46.34 | ze | initrd stuff's cool for liveboot media and such cases but not so great for a real installed kernel imo :p |
| 04:48.27 | ze | *shrug* doesn't matter though, this just built a kernel and a tarball of the modules heh |
| 04:49.12 | ze | and the modules into the sysroots/ tree |
| 04:49.14 | ze | heh |
