unfortunately this plattform supports gpg (GnuPG) 1.4.21 only.
This is quite interesting idea. Indeed according to OpenWrt 18.06 package list there is no GnuPG 2 available. You would probably have to crossbuild it locally and upload. Aside from GnuPG2, you would need the scdaemon package.
Since you have OpenSC installed, it might not be required though. It depends however whether this version supports the Nitrokey Start (should be). You need to have running pcscd deamon with proper access rights (by either being root or configure them in some other way). OpenSC tools are connecting to the pcscd, and through it accessing the smart card.
Cross-building the latest OpenSC v0.20 might be easier than GnuPG, since the packages are available for not so older version.
Please try to run pcscd and redo pcsc_scan call, or any other OpenSC command, e.g. pkcs11-tool -I.
