3.6. HPS SDRAM ECC Logging Problems

Description

While the HPS SDRAM ECC operates correctly, there can be minor issues logging the error address in the ecc_hmc_ocp_slv_block register block. Address logging errors can occur in the following situations:

  • During a read burst, if the HPS SDRAM controller is configured to interrupt on all errors (INTMODE.INTONCMP = 0) and if a single-bit error (SBE) occurs during an odd beat of a burst, the SERRADDRA register does not correctly store the address of the errant transaction.
  • During a read burst, if a double-bit error (DBE) occurs during an odd beat of a burst, the DERRADDRA register does not correctly store the address of the errant transaction.
  • During a read or write access, if the external parity error signal is asserted, the DERRADDRA register is erroneously updated.

Workaround

  • For systems executing read bursts where the frequency of single-bit errors is low, you can use interrupt-on-compare match mode to ensure the correct SBE address capture in the SERRADDRA register. To use this mode, set the compare value to 1 by setting the following register fields:

    • INTMODE.INTONCMP = 1
    • SERRCNTREG.SERRCNT = 1
  • There is no workaround to correctly store the errant address in the DERRADDRA register for double-bit errors that occur on the odd beat of a read burst.
  • There is no workaround to prevent the DERRADDRA register from being erroneously updated during a read or write access when the external parity error signal is asserted.
