How do I mine a first block ? (POC/POC2)

[markerz194]

I build it using bitcoinhd sourcecode. (new altcoin)
I try plotting and mining using miner-burst software, but with error.
(https://github.com/JohnnyFFM/miner-burst/releases)

Code:

{"code":-1,"message":"Is initial block downloading!"}

my coin.conf

Code:

rpcuser=user
rpcpassword=1234
rpcallowip=127.0.0.1
rpcport=7777
listen=1
server=1

current number of block = 0
wallet is connection 2 active.
