Hi Tixy and other,
Similar to patch 01/11, build robot found a building error in this patch when
ARM version
is lower than 4. In such processors 'blx' instruction is unusable.
I have posted a new version of this patch, which has following code change:

Tixy, could you please collect it into your repository and test again?
Thank you!
