Picore-3.14.4+ ----> UINPUT / EVDEV as modules

[lykkedk]

Goodmorning.

For testing your new kernel no need to rebuild tcz's. You can add modules to initrd or to put all modules not in base to a single tcz. It is ok to see wether these modules solve your original issue or not. If we can confirm, I will move them to modules in 6.0 kernel.

How do i actually make a .tcz with remaining kernel modules, and do i have to use modules with .ko, or with .ko.gz (modules inside initrd is with .ko.gz)

Jesper.

create a folder mymodules somewhere and copy modules to mymodules/lib/modules/... Type

Code: [Select]

mksquashfs mymodules mymodules.tcz
and got the extension.

Of course install squashfs-tools-4.x.tcz before.

  SuperB...

Through i seem to be doing something wrong.

tc@box:~$ uname -ra
Linux box 3.14.6-piCore #1 PREEMPT Mon Sep 8 15:12:35 CEST 2014 armv6l GNU/Linux

1. line Dmesg
Linux version 3.14.6-piCore (jesper@jlp) (gcc version 4.7.1 20120402 (prerelease) (crosstool-NG 1.15.2) ) #1 PREEMPT Mon Sep 8 15:12:35 CEST 2014

The initrd, i made yesterday with 109 modules inside, where all with extension .ko.gz

So now i tried to make :

mksquashfs mymodules mymodules.tcz

tc@box:~$ tce-load -i mymodules
mymodules.tcz: OK

So no matter if i use modules directory with .ko.gz, or modules directory with .ko i got fault when trying to load
I both have a directory with modules, with extension .ko.gz
And a directory with extension .ko

I tried to make mymodules.tcz with both, with same result

And  Does it matter, that i took all modules including the 109pcs, allready buildin my initrd ?

Jesper.

Invalid module format means module was built for a different kernel than you are actually using or built wthe a different toolchain.

Use modinfo command to check module.

[lykkedk]

Yes...

I see now.

See line lrwxrwxrwx    1 root     root            45 Sep  8 13:41 kernel.tclocal -> ../../../usr/local/lib/modules/3.14.4-piCore+/

Does not match ??

It must be a fault in my initrd, as i am pretty sure my modules is build as per kernel.

Mixing 3.14.4 and 3.14.6

[lykkedk]

  .. uhhh Anyway...

Mixing 3.14.4 and 3.14.6

Not sure ! ?

While looking at this link here (inside initrd) :

The kernel.tclocal links to "false" kernel

Can't i just do
root@box:/tmp/myinit/lib/modules/3.14.6-piCore# rm kernel.tclocal
ln -s ../../../usr/local/lib/modules/3.14.6-piCore kernel.tclocal

Or was it something else i had to do ?

Jesper.

[lykkedk]

  It's working.

I made the link inside the initrd point to the right kernel, and now i can load modules from
Mymodules.tcz

Doing modinfo, also tells me, i am using kernel 3.14.6 now.

So, after having build module evdev and uinput, i can load them, and when trying to load LIRC, there
Is no more complains about missing --uinput etc... Etc..

  bad thing through, i fighted the lirc 3 hours now, still cant get it to work.

Anyone here ever got it working ?..(i did once, around a half year ago on other picore)

I have compiled both lirc-0.9.0 (version i one had working) and the newest lirc-0.9.1a, there is a dep. Help2man, which i also compiled.

All 3 progs. I have as homemade .tcz

I havent sent those tcz to tinycore yet, as i wont before i got it working on my own.

If anyone will like to try it, i can sent them, no problem 

Btw. Lirc reciver is homemade connected to gpio 18, and is working on another distro, so hardware is still good!

My old working lirc link is here ::
