TPS65983EVM: tps65983evm boosterpack can't support 4cc command?

Part Number: TPS65983EVM

I’m learn the TPS65983 with the BoosterPack board, but I found it always return “!CMD” to my 4CC command,

I just want to confirm that whether the BoosterPack firmware supports 4CC commands?

If not, could you please tell me how to support 4CC commands?

Thanks a lot for your help,
