well, I tried that with the Apalis TK1 and it does not work, cuz there are some drivers that are not compatible with the RT patch and would have to be changed, which I am not capable of doing. I got the Apalis IMX6Q running with the RT image using bitbake and the corresponding config. But nevertheless, it would be sweet if you guys could fix the issue with above mentioned problem. I suppose its just a missing file, which can be fixed relatively quickly. Else you should change the corresponding article, because then its just incorrect.
It would be probably possible to fix issues with wget, but I doubt that the packages still install/work on current images. Note also that the kernels are 2 years old… For a new project we recommend to use a more recent kernel.
I agree, we should update the article. I will do so today.
Note also that we just recently updated our meta-toradex-nxp 2.8 layers and added the linux-toradex-rt recipe for Linux 4.9 with PREEMPT RT.
