LIRC on UDOO Neo

Hi,
Anyone tried/been able to run lirc (Linux Infrared Remote Control) on UDOO Neo?

I followed http://funny-embeddings.blogspot.in/2013/12/udoo-adding-ir-and-building-lirc-kernel.html
All works fine until I try to load module. It fails with

udooer@udooneo:/lib/modules/3.14.56-udooneo-02013-gabdce68$ sudo modprobe lirc_udoo gpio_in_pin=25 debug=1
modprobe: ERROR: could not insert 'lirc_udoo': Exec format error

 

I am not at all a linux expert but loading a module compiled for an older kernel is no guarantee for success. Also the Neo is something different than a dual or quad where the original blog is talking about. Seems that you have to recompile and/or change the source to match the Neo pin layout. I personally have no other clue.

 

You module isn't correctly cross compiled for ARM, its most likely compiled for x86. You may be able to read the executable header info by:

Code:

readelf -h lirc_udoo.ko

It should show details like below if you cross compiled correctly:

Code:

ELF Header:
  Class:                             ELF32
  Data:                              2's complement, little endian
  Version:                           1 (current)
  OS/ABI:                            UNIX - System V
  ABI Version:                       0
  Type:                              REL (Relocatable file)
  Machine:                           ARM

 

Will confirm this later today. However I did compiled it on UDOO Neo itself. It should have built for ARM IMHO.
