DDP Get/Set requests are rejected as unknown commands

DDP Get/Set requests are not serviced. Protocol stack rejects them with status "unknown command" ulSta= 0xC0000004. 

In this case, if firmware is with edited taglist to start DDP in passive mode, the host application is stuck - can not activate it and can not be configured at all.

1. Try to use HIL_DDP_SERVICE_GET_REQ - ulCmd = 0x1EEA, ulDest=0x20, with data 0x00000070 to get the DDP state

2. Check confirmation packet

Expected results:

HIL_DDP_SERVICE_GET_CNF, ulSta = 0

Actual results:

HIL_DDP_SERVICE_GET_CNF ulSta = 0xC0000004 - Unknown command
