Cellular Network Infrastructure » Radio Access Network » OsmoBSC

I've just installed the 201705-nightly image on a sysmoBTS 1002:

root@sysmobts-v2:/tmp# osmo-bts-sysmo  --version
OsmoBTS version 1.6.0.37-e464e
root@sysmobts-v2:/tmp# opkg list | grep osmo-bts
osmo-bts - 1.6.0+git18+e464ef6524-r1.18.1

When trying to bring it up against a remote osmo-bsc, I'm getting an OML Radio Channel(00,00,00) Set Channel Attrributes NACK from the BTS, with the BTS complaining:

<0001> ../../../git/src/common/oml.c:454 OC=CHANNEL(03) INST=(00,00,00): Sending FOM NACK with cause Parameter value outside permitted range.

The BSC config contains BSIC 63 and TSC 7.

Somehow the BSIC doesn't seem to be set before the TSC7 of TS0, and then the BTS still has its zero-initialized BSIC?
