I tried running both the SystemReady band ACS and SCT for BBSR suites using the v24.11_3.0.0-BET0 ACS image.
Both testing is hitting this error during the run: Error-Input address is not aligned. Masking the last 2 bits

Hi @nvidiaarm,

Can you please provide more information on this, at what point of ACS execution, or which test are you observing this error. Please attach corresponding logs.

Best Regards,

Hi @nvidiaarm,

Upon reviewing the error message, it appears that the issue may stem from the SBSA/BSA ACS suite execution and unexpected to encounter such an error during BBSR SCT. Further analysis suggests that the error might be triggered by an unaligned address encountered by pal_mmio_read[1]. (unaligned address might be referenced in system's ACPI info) Please provide log snippets to further debug and root cause the issue.
