hi: my gumstix runs a 2.6.10 kernel and the tarball offered by wiki doesnot wor= k on it. when I insmod the module, I was told an invalid format. I guess I need to rebuild the module for 2.6.10. anyone incountered the same thing? thanks wei |

The kernel refuses to load modules that are built for a different kernel version. So if you want to stick to the 2.6.10 kernel, you'll need to rebuild the modules from source. Note that if you want to use the i2c stuff, there have been some patches made to the kernel that you'll need to backport. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

hi dave: I think I'd better upgrade the kernel to adapt cause all my present build root is for kernel 2.6.15. what I am wondering is if it is safe to overwrite kernel image and modules on gumstix. if part of process fails, then I need to refresh it? thanks wei On 2/19/06, Dave Hylands <dhy...@gm...> wrote: > > HI Wei, > > On 2/19/06, wei guo <guo...@gm...> wrote: > > hi: > > my gumstix runs a 2.6.10 kernel and the tarball offered by wiki doesno= t > > work on it. when I insmod the module, I was told an invalid format.

For 2.6.15, you probably want to upgrade the entire root_fs (i.e. start with a whol new image). I've never tried just updating part of the file system.

hi Dave: do you mean I should copy all the files in build_arm_nofpu/root/ to overwrite whole system on gumstix? http://www.gumstix.org/tikiwiki/tiki-index.php?page=3DTips+and+Tricks it is said that "If you upgrade to a new kernel, you just need to replace the /boot/uImage file on the gumstix, and any modules in /lib/modules/..." furthor more, the new built root_fs for 2.6.15 ocupies more than 7M space. so for basix-gumstix which has only 4M flash, extra storage is needed? thank you very much. wei On 2/19/06, Dave Hylands <dhy...@gm...> wrote: > > Hi Wei, > > > I think I'd better upgrade the kernel to adapt cause all my present > build > > root is for kernel 2.6.15. > > what I am wondering is if it is safe to overwrite kernel image and > modules > > on gumstix. if part of process fails, then I need to refresh it? > > For 2.6.15, you probably want to upgrade the entire root_fs (i.e. > start with a whol new image). > > I've never tried just updating part of the file system.

Hi Wei, > do you mean I should copy all the files in build_arm_nofpu/root/ to > overwrite whole system on gumstix? Well, I was thinking that you'd probably want to reflash the entire image, because alot more stuff has changed than just the kernel and the modules (like all of the udev stuff). > http://www.gumstix.org/tikiwiki/tiki-index.php?page=3DTips+and+Tricks > it is said that "If you upgrade to a new kernel, you just need to replace > the /boot/uImage file on the gumstix, and any modules in /lib/modules/...= " > furthor more, the new built root_fs for 2.6.15 ocupies more than 7M > space. so for basix-gumstix which has only 4M flash, extra storage is > needed?

hi dave: could you send me a kernel image for 200M Hz? I just upload my own kernel into flash, after it displayed : Umcompressing Linux.................................... done, booting the kernel. then it stopped.

The kernel image doesn't change for different MHz, just u-boot. You may want to disable C++ for the root_fs that you actually load to the gumstix (especially if you only have 4Mb). The C++ libraries add quite a bit of space. What I've done is to use external flash (i.e. MMC card to hold the C++ libraries). What I really need to do is see if I can get avrdude to work, since avrdude is written entirely in C and therefore doesn't require the C++ libraries. And actually, none of the above explains why it would stop after the uncompressing lionux message. What does u-boot have for your console? Craig - Was the updated u-boot just to add jerase? Or was there some other reason that u-boot needed to be upgraded to use a newer kernel? -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

hi dave: I use kermit to upload the image file, after that, I use cmp.b to check the file in flash written without problem. then boot, after the kernel umcompressed, I waited for a long time and nothing goes on. so now I am working on building the image file again to see if it will work... thanks a lot. wei On 2/20/06, Dave Hylands <dhy...@gm...> wrote: > > > could you send me a kernel image for 200M Hz? > > I just upload my own kernel into flash, after it displayed : > > Umcompressing Linux.................................... > > done, booting the kernel. > > then it stopped. > > I think my kernel doesnot work. this kernel is what I just built from > the > > latest build root with c++ enabled and set to NOT 400 Mhz. the final > size is > > 3448232 root_fs_arm_nofpu. > > thank you. > > The kernel image doesn't change for different MHz, just u-boot. > > You may want to disable C++ for the root_fs that you actually load to > the gumstix (especially if you only have 4Mb).

hi: I use revision 773 to build a kernel image of 2.6.11, which runs well. the u-boot version is 1.1.2. but the last several times I tried on 836 or 837 revision which is 2.6.15 kernel, it didnot boot the system after the kernel image is uncompressed.

I just wonder > should I also flash u-boot? It's often not a bad idea to update u-boot as well (the current version is up to 1.1.4 now). But likely the only change you need to make is to change the u-boot bootargs variable to use root=1f01 instead of root=1f02. ie interrupt booting by pressing a key to enter uboot, then: GUM> set bootargs console=ttyS0,115200n8 root=1f01 rootfstype=jffs2 GUM> saveenv GUM> bootd That should then work. If not, then let us know what the error message is. C |
