hello. my sl-5500 shuts off when i hold down the right arrow for more than a few seconds. i've come across a few posts and internet sites that i think will fix my problem but i've never made my own kernel for my zaurus and i'm afraid i might brick it.

this is a patch for the kernel that is supposed to fix the problem:

https://www.oesf.org/index.php?title=Marcan_fix

i'm using this cross compiler:

http://www.tyrannozaurus.com/feed/contribs...-2.95.3.tar.bz2

and i'm using this kernel:

http://www.tyrannozaurus.com/feed/contribs...rom3_10.tar.bz2

and i'm trying to follow these directions but they don't explain what to do after "make dep":

http://www.tyrannozaurus.com/feed/contribs...ides/kernel.txt

i did a make and wound up with a vmlinux that's about 2 megs. which sort of frightens me because the pdaxrom image that i flashed my z with was more like 1 meg. but the compilation process went smoothly. i'm pretty sure the kernel was compiled correctly.

is it safe for me to rename vmlinux to zImage and reflash with it and the pdaxrom beta1 initrd.bin?

also, and please forgive my ignorance on this, but do i need to compile new modules? the kernel versions on the old and new kernel appear to be exactly the same (2.4.18-rmk7-pxa3-embedix). is the new kernel going to be compatible with the modules that pdaxrom 1.1.0beta1 comes with?

if pdaxrom doesn't start after i flash my z, will i be able to reflash with the old zImage or will my z be bricked?

thanks, static

erm, i think i was supposed to "make bzImage" instead. my bzImage is 870k or so. sorry, i haven't compiled a kernel for a long time.

but i still don't know if it'll brick my zaurus if i flash with it.

i got your message,

ive never gone as far as building a rom afaik , just configuring a kernel source far enough to build a 3rd party app's module against it...

afaik you wont brick it but i dont have the exp. though i have flashed alot, quite a few of them unsuccessful, ive always made it good again.

good luck, it is annoying bug i would like fixed too.

thanks for your reply. i flashed my z with the new zImage, powered it up, and it displayed a screen that said "Sharp" in red letters. smile.gif
but i reflashed with the pdaxrom kernel and it starts up again. i'll try a few more kernels.

well, holy cow. i managed to make a kernel that boots with the pdaxrom initrd and then panics when it's unable to mount a root fs.

more to come later if anything interesting happens.

i used a kernel config file from pdaxrom for the sl-5500 on the kernel mentioned in the first post to get a booting kernel. it appears to point to the same ramdisk /dev/mtdblock4 (major 1f, minor 04) but it panics.

here's the panic i get:

VFS: Cannot open root device "mtdblock4" or 1f:04
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 1f:04

geez. how annoying. is it possible that i need to change something about the ramdisk too?

hopefully it's just something about the kernel that needs changing.

looks like i have a bit of reading up to do if no one has a simple solution to my problem.

i didn't have initrd support built into the kernel. d'oh!

but it's still borked. perhaps cos i don't have the default initrd size set correctly.

RAMDISK: Couldn't find valid RAM disk image starting at 0.
Freeing initrd memory: 3072K
VFS: Cannot open root device "mtdblock4" or 1f:04
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 1f:04

bed time. i'll dink around with it later.

thanks for the log.

it _appears_ that the root device mtdblock4 that my kernel is failing to open is created earlier up in your log:

MTD Sharp chip driver <ds@lineo.com>
SA1100 flash: probing 32-bit flash bus

0x00000000-0x00020000 : "Angel Monitor" <- #0

0x000c0000-0x001c0000 : "kernel" <- #3

0x00fe0000-0x01000000 : "angel stuff"

perhaps my kernel isn't configured correctly to create this device, whatever it is.
resizing my default initrd size in the kernel didn't work.

fun stuff. i made my kernel panic right after it _should_ have done this:

instead, it did this:

that would explain the lack of mtdblock4, i think.

./Documentation/arm/SA1100/Assabet

that document in the kernel tree has instructions that look relevant. it contains instructions for configuring the kernel. i followed the instructions. it created a .config file for me. i then did a make menuconfig, copied the changes it made to the MTD section to paper, put the old kernel config back in place, and updated it's MTD settings manually via another make menuconfig.

the result is a small improvement:

i've managed to get it to boot but it appears that the touch screen isn't working. i haven't patched the right arrow bug yet either.

anyway, the angstrom project has a complicated .... build system... thing ... that i borrowed configuration info from to get my kernel config to work. i'm really not sure how i managed to make it boot but heck, it works. i'll just stay the hell out of the MTD configuration screen and it should work out ok.. i hope.

OH. the angstrom build system also has like 10 or 15 patches for the 2.4 kernel on the collie. many of these patches look important for getting all the 5500s hardware to work right. the biggest one is "cacko.patch".. it looks like it contains mtd stuff so i bet it's required if you want a kernel that boots. i applied it. it also provides the tiny console font that pdaxrom uses... and a ton of other stuff too, i'm sure. i'll attach the other patches to this thread once i've decided if they are needed or not.

i've attached cacko.patch, and my kernel config.

this is a list of the patches that angstrom appears to apply to the kernel. the openswan patch didn't quite apply correctly so i chose not to apply it in my instructions below.

the touchscreen still doesn't work after applying all these patches. either i am leaving something out of the kernel config or there is some other patch that pdaxrom uses that i don't have... this fixed the right arrow bug, though smile.gif

who knows what else fails to work in this kernel. i haven't done much testing.

all of these patches are in an attachment to this post along with the kernel config file i used.

put the contents of the cross sdk under /usr/local/arm (see my first post for a link to the sdk).

the compiler binaries should wind up in /usr/local/arm/2.95.3/bin once you uncompress the cross sdk tarball.

iirc, there are some hardwired paths in the cross compiler that require it to be in that directory.

create a directory to work in.
put the bziped kernel tarball (my first post links to it), the kernel.config file and all patches in this directory.
cd into the directory.

cp kernel.config linux/.config

cd linux
export PATH=$PATH:/usr/local/arm/2.95.3/bin/

for some reason, i need to do a make menuconfig and then immediately exit choosing to save my kernel config at this point. otherwise, the kernel will fail to compile. dunno why.

make menuconfig
select "Exit"
select "Yes" at the prompt

make dep && make bzImage

copy the newly created zImage from arch/arm/boot/ to your cf card along with the pdaxrom beta1 initrd.bin

reflash.

you might try leaving out the logo.patch if you don't like the openzaurus logo appearing at the top of the screen. lol.
