Using 8 microsteps for RA/DEC leads to compilation failure

[Probably a FW bug, not a GUI bug, I can't confirm]

Default microsteps for RA/DEC in OAT Firmware Configuration web V2.15 is 8.

// Unique ConfigKey: TR:OAT,FWT:L,SL:N,HS:N,BD:M21,RST:N9,RDO:TU,RATP1500:O90:A3000:V1800:S8:T256:,RTR:N,RT:1,DS:N9,DDT:TU,DATP1500:O90:A3000:V1800:S8:T256:,DT:1,DLIN90:D45:,STL:N,DY:LCD,GP:Y,LM:N,FC:N,APT:N,RAH:Y,RAHAP53:S10:

Compilation fails with this default setup. But it works changing it to 16.
