I installed OS2008-HE, which is also working quite correctly (I have an issue with WiFi but I'll address it later). My plans with this machine is to upgrade it to a Debian distro (I'm quite comfortable with Debian). Before this can be achieved, I need to install a recent kernel on the N770. The current Debian stable kernel is 2.6.32. I installed a cross-compiling environment (scratchbox2) on my PC and compiled the 2.6.32 kernel for the N770. I have a zImage that I can flash on the device. I compiled my kernel with the following commands: sb2 make n770_defconfig sb2 make zImage sb2 make modules I've flashed the kernel, modified the initfs to include 2.6.32 modules and tried to boot, but it fails. I have the Nokia splash screen for around 20 seconds, then the device halts. I enabled RD mode, expecting messages to be displayed on spash screen, but no message is printed. I guess the kernel is not even loaded. Is it possible to have a vanilla kernel working on such a device (I guess so) ? Are there any specific steps I should have run to have my kernel working (bootloader stuff, etc.) ? Did I miss something (I also guess so) and what ? Are there (for testing purpose) any ready-to-use recent kernel images for N770 ? Thanks. Sébastien Hello, Maemo systems needs its own patched kernel by Nokia. Prior N900 device kernels contains some close source kernel drivers which working only on some specified kernel versions. So upstream kernels will propably not work with Maemo. If you want to use another linux distribution you propably want to try use patched Nokia kernel which working. But if your distribution depends on some new version, then you have problem. Upstream kernels does not have proper support for Nokia devices. More drivers missing and other does not working correctly. Also there is no support for watchdogs (for 770/N8x0) in upstream kernels, so you get instant reboot after few seconds. You can try to look at meego/mer/nemo team. They have some updated kernels for N8x0, so maybe you find something for 770 too. Btw, for testing kernels, do not flash it into device, rather load it. Nokia flasher has option for it (-l) which load kernel+initfs images via usb and then run it without flashing. 0x flasher has this option too. And do you really want to have Debian on Nokia 770? Maemo is Debian like distribution, so you have dpkg/apt-get on device and you can compile and install deb packages without problem. -- Pali Rohár pali.ro...@gmail.com signature.asc Description: This is a digitally signed message part. ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
Re: Kernel compilation
Thanks for your quick answer. Le mardi 22 janvier 2013 à 11:40, Pali Rohár a écrit : Maemo systems needs its own patched kernel by Nokia. Prior N900 device kernels contains some close source kernel drivers which working only on some specified kernel versions. So upstream kernels will propably not work with Maemo. Bad news… If you want to use another linux distribution you propably want to try use patched Nokia kernel which working. But if your distribution depends on some new version, then you have problem. Upstream kernels does not have proper support for Nokia devices. More drivers missing and other does not working correctly. Also there is no support for watchdogs (for 770/N8x0) in upstream kernels, so you get instant reboot after few seconds. That's the problem I have. I installed a small Debian system in a directory and tried to chroot to it, which failed because kernel (2.6.16 in 0S2006) is too old. You can try to look at meego/mer/nemo team. They have some updated kernels for N8x0, so maybe you find something for 770 too. I had a look to MER project but quickly gave up because RPM-based. I'm comfortable with Debian-based systems, but not that much with Red-Hat-based ones. I'll try to extract a kernel from one of these MER images and hope it works ! Btw, for testing kernels, do not flash it into device, rather load it. Nokia flasher has option for it (-l) which load kernel+initfs images via usb and then run it without flashing. 0x flasher has this option too. Yes, that's the way I'm doing it, thanks for the advice. And do you really want to have Debian on Nokia 770? Maemo is Debian like distribution, so you have dpkg/apt-get on device and you can compile and install deb packages without problem. Not that much, what I want is a free system (at least as free as it can be) with security-related updates, which is no more possible with Maemo on n770. I'll go deeper in MER project images and post feedback later to this list. Thanks.

Re: kernel compilation help
This seems to work if I compile from within an Ubuntu install on a VM using VMWare, but after installing scratchbox, maemo SDK, and Nokia binaries to a native Fedora system I get the errors I wrote about previously.

Re: kernel compilation help
Thanks! I will get the official version next month, but I am trying to use this for a course project, so time is of the essence. Hopefully I will not run into the same problems as the bora release.

Re: kernel compilation help
Hello, I didn't try this yet, but I have doing this in the previous version, 3.1 and I could use the wifi following the instructions in the early guide, but since I have a particular interesting on having wifi interface working with 4.0, I can't see any instruction about how to compile the wifi driver. Is there a special step that I should follow? Another question: is it possible to have a Linux omap kernel, let's say 2.6.24 (git kernel), rather than 2.6.21 and still have the wifi interface working?
