Re: [maemo-developers] flasher not flashing rootfs?
> The minimum size for a rootfs is 4MB at the moment. My testing shows that a jffs2 file of *exactly* 8 Mb (8,388,608 bytes) will NOT flash. Anything bigger than that (the next largest jffs2 image is 8,389,752 bytes) WILL flash. Note that this is the jffs2 image as produced by tar2jffs, including the sumtool step - i.e. this is the size of the file transferred to the 770, not the output of mkfs.jffs2. Thanks for the tips, I'm back to work now :-) DJ ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
Re: [maemo-developers] flasher not flashing rootfs?
> The minimum size for a rootfs is 4MB at the moment. The image was a little bigger than 4Mb, but that was enough to help me out. I added gcc to the rootfs (now 12Mb) and if flashes now. I'll try to track down a more precise minimum size. Can you add a message to the flasher tool? Or release the sources so I can?

Now I can boot off the mmc card. I need to get a bigger card if I want to go much further with this, though ;-) > Flashing rootfs can be done with this too when booted from mmc. Tried > myself. Assuming you have a big enough mmc to hold a full rootfs image. I still only have the pre-supplied 64m card. But, I'll keep that in mind. It would be better if the flasher just worked, or at least told me why it wasn't. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Maybe your image is too small (4MB from your output? some test?) and this is bug/feature of flasher? In any case if you are sure the image is ok and want experiment with booting from mmc, have a look here http://fanoush.webpark.cz/maemo/#initfs for precompiled mtd-utils. Flashing rootfs can be done with this too when booted from mmc. Tried myself.

I assumed there was some reason, but (1) it doesn't tell me, and (2) there's no source, so I can't figure it out myself. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
