Hi,
for two EVM test, you'd better not use RP01 interface, if it is not definitely required. our BOC also has pin connector for RP01 burst and clock but we haven't tested at all and cannot guarantee the quality of burst signal and clock.
our recommendation is just using common clock on BOC with simple PHYSYNC, RADSYNC sync pulse from TIMO0 of the first EVM.
Please see EVM and BOC user document for more detail.
Regards,
Albert
