Structure Pointer with CRAM Status details
- CfrStatusInfo->Status: Provides details about
CRAM scan
- Bit [31-25]: Reserved
- Bit [24:20]: CRAM Error codes
- 00001: Unexpected CRC error when CRAM is
not in observation state
- 00010: Unexpected ECC error when CRAM is
not in Observation or Initialization state
- 00011: Safety write error in SEU handler
- 00100: ECC/CRC ISR not found in any row
- 00101: CRAM Initialization is not done
- 00110: CRAM Start Scan failure
- 00111: CRAM Stop Scan failure
- 01000: Invalid Row for Error Injection
- 01001: Invalid QWord for Error Injection
- 01010: Invalid Bit for Error Injection
- 01011: Invalid Frame Address for Error
Injection
- 01100: Unexpected Bit flip during Error
Injection
- 01101: Masked Bit during Injection
- 01110: Invalid Block Type for Error
Injection
- 01111: CRC or Uncorrectable Error is
active in CRAM
- 10000: ECC or CRC Error detected during
CRAM Calibration in case of SWECC
- Bit [19-17]: Reserved
- Bit [16]: CRAM Initialization is completed
- Bit [15-14]: CRAM Correctable ECC error
status
- 00: No Correctable error encountered
- 01: Correctable error detected and
corrected
- 10: Correctable error detected but not
corrected (Correction is disabled)
- 11: Reserved
- Bit [13]: CRAM Scan internal error
- Bit [12]: CRAM Invalid Error Location detected
- Bit [11]: CRAM Correctable ECC error detected
- Bit [10]: CRAM CRC error detected
- Bit [09]: CRAM Uncorrectable ECC error
detected
- Bit [08]: CRAM ECC error during Initialization
- Bit [07]: CRAM Calibration Timeout error
- Bit [06]: CRAM Fatal/Error State
- Bit [05]: CRAM Error Injection State
- Bit [04]: CRAM Idle State
- Bit [03]: CRAM Correction State
- Bit [02]: CRAM Observation State
- Bit [01]: CRAM Initialization State
- Bit [00]: CRAM Scan is included in design
- CfrStatusInfo->ErrAddrL: This stores the low
address of the last 7 corrected error details if correction is enabled
in design.
- CfrStatusInfo->ErrAddrH: This stores the high
address of the last 7 corrected error details if correction is enabled
in design.
- CfrStatusInfo->ErrCorCnt: Counter value of
Correctable Error Bits

Returns
This API returns the success or failure.
-
XST_FAILURE: If NULL pointer reference of CfrStatusInfo
-
XST_SUCCESS: On successful read from PMC RAM
