Installing packages to arm_arm926ej-s

Hi,

I have an IoT router with arm_arm926ej-s and I should install the folowing packages:
-libtrt
-f2fs-tools
-gdisk
-libjpeg
-liblcms2.so.2
-libnss

Where can I get them? I did find all those libs for ARM64 and for cortex-A9 but of course I am getting an error that this is the wrong architecture.

Thanks
Janko
