This function is used to initialize CRAM scan on targeted SLR from user application. Primarily this function sends an IPI request to PLM to start CRAM Scan Initialization, waits for PLM to process the request and reads the response message.

Prototype

XStatus XSem_Ssit_CmdCfrInit(XIpiPsu *IpiInst, XSemIpiResp *Resp, u32 TargetSlr);

Parameters

The following table lists the XSem_Ssit_CmdCfrInit function arguments.

Table 1. XSem_Ssit_CmdCfrInit Arguments
Type Member Description
XIpiPsu * IpiInst Pointer to IPI driver instance
XSemIpiResp * Resp Structure Pointer of IPI response
  • Resp->RespMsg1: Acknowledgment ID of CRAM Initialization(0x10301)
  • Resp->RespMsg2:
    • if Broadcast Status of Cfr Init in Master
    • else : Status of Cfr Init in Target SLR
  • RespMsg3, 4 and 5 are updated only in case of broadcast
  • Resp->RespMsg3: Status of CfrInit in Slave 1
  • Resp->RespMsg4: Status of CfrInit in Slave 2
  • Resp->RespMsg5: Status of CfrInit in Slave 3 Status of CRAM initialization: 0x01000000U - ECC/CRC error detected during calibration in case of SWECC 0X00000080U - Calibration timeout 0X00002000U - Internal error
u32 TargetSlr Target SLR index on which command is to be executed
  • 0x0 : Target is master only
  • 0x1 : Target is slave 0 only
  • 0x2 : Target is slave 1 only
  • 0x3 : Target is slave 2 only
  • 0xF : Broadcast for all devices

Returns

This API returns the success or failure.
  • XST_FAILURE: On CRAM Initialization failure
  • XST_SUCCESS: On CRAM Initialization success
