HI @chetan-rathore ,

we are still observing the BSA hang issue at 502 test on the latest prebuilt binary .

@smangali-qc , will check the latest logs and share our observations.

Hi @smangali-qc,

Apologies for the delay in responding, and thank you for sharing the higher verbosity logs.

Based on the logs, there is no conclusive indication of why the test is hanging at the point captured. The 500-series tests are designed to put the PE into sleep, program various interrupts, and verify that the PE wakes up correctly in response to those interrupts.

In the 501 test, it appears that the PE is waking up due to an event or interrupt that was not programmed by ACS, leading ACS to skip the test. The same flow is seen for the 502 test; however, in this case, a hang is observed on your side.

To help debug and identify the root cause,

• could you please share details on any potential events or interrupts that might be waking up the PE unexpectedly?

• Additionally, please try running only the 502 test and confirm if the hang still occurs using the following command: Bsa.efi -t 502

• It would also be helpful to know whether this issue is specific to one system or observed across multiple systems on your side. For reference, we have tested on several systems and have not observed this issue.

Thanks,
Chetan

HI @chetan-rathore ,

Will check and get back on this

Additionally, please try running only the 502 test and confirm if the hang still occurs using the following command: Bsa.efi -t 502

this command Bsa.efi -t 502 is not able ot execute 502 test, we tried different test number aswell, it did not work. below are the logs.

we ran on two systems, both are showing same symptoms

HI @chetan-rathore ,

any update on this?

Hi @smangali-qc,

Apologies for some delay, the BSA ACS was undergoing some major framework changes, hence waited for that to completed before requesting any new runs.

BSA ACS has moved from test id to rule based approach, now selective tests can be run using the rule id.

Please use the latest Bsa app for DT platforms: https://github.com/ARM-software/sysarch-acs/actions/runs/19839084901/artifacts/4730511732 and run only the B_WAK_03 test using below command.

Bsa.efi -r B_WAK_03 -v 1

-r is to select rule or rules

Expected output is in below format

SMMU_INFO: SMMU index 00 version : v3.1
Peripheral: Num of USB controllers : 0
Peripheral: Num of SATA controllers : 0
Peripheral: Num of UART controllers : 1
SMBIOS: Num of slots : 0

Selected rules: B_WAK_03

At your side, you might see hang after u001_entry line

HI @chetan-rathore ,

thanks for sharing the debug binary, we are still observing the test execution getting stuck
same logs are observed with different test case B_WAK_01.

@smangali-qc,

Is the stuck observed at below prints ?

PMU compatible value not found for index:6
PMU compatible value not

It will be great if you can attach the bsa logs

Hi @smangali-qc,

The DT v3.1.1 release is scheduled for next week, so it would be ideal to have this issue resolved in that release.
If you can share the logs, it will help us expedite the investigation and resolution.
