[maemo-developers] [maemo-developers] How large may the kernel-image be?

[From: Peter.Hagg at tietoenator.com]

Hi, 

 as mentioned by Kalle below, kernel needs to be compiled with gcc 3.4. Also, in your earlier post you mentioned maemo 1.0 scratchbox. Does this mean you have maemo 1.1 installed, or what? In order to be able to compile the kernel successfully, you need maemo 1.1, and preferably the latest 0.9.8 series Scratchbox (0.9.8.5 is the one kernel recompilation has been tested with, but 0.9.8.6 should work as well). 

You should definitely take a look at the Kernel Compilation HowTo, available here: http://maemo.org/maemowiki/HowTo_KernelCompilation. This piece of documentation describes the necessary setup and recompilation procedure.


Regards,

Often the reboot cycle is from some application deemed as Truly
Needed(tm) dying (at which point the failsafe mechanism boots).
Without dedicated devices the recovery could be tricky, but one can
try with setting the 'no-lifeguard-reset' r&d flag[1] with flasher and
praying it will boot up to having a GUI (or if installed, sshd)
available for debugging.

AFAIK, you need to use gcc3.4, I've succesfully compiled a kernel for
the 770 with the

  arm-linux-gcc3.4.cs-glibc2.3

toolchain (with wlan working etc), so it indeed could be that the
kernel fails to load some modules and someone gets confused over it.
