The above is my geth installation, I need to initialize testnet with some default balance for some address - how can I do this? I tried with the genesis.json from https://github.com/ethereum/go-ethereum/wiki/Private-network and initialized the private block chain, created an account, replaced the address in the custom genesis file with that and re-run the init, but it failed with
Fatal: Failed to write genesis block: database already contains an incompatible genesis block (have 15ecff6ddb9d4db4, new 834a88447f2091cc)
How can I add some balance to the address?
