PBIST Example/FT/UT (basically any app of PBIST that requires individual tests on each controller and their associated aux devices) are failing in UART bootmode, because of some issue with the sciclient processes associated with TISCI_DEV_A53SS0_CORE_0 (and possibly more devices). Below is example log for PBIST Example in am62px:
PBIST Test Application Starting PBIST failure insertion test on A53 MPU CLUSTER0, index 0... Sciclient_pmSetModuleState 0x87 ...FAILED Delta Cores prep time in micro secs 1423 Delta PBIST execution time in micro secs 27 Delta Cores restore time in micro secs 2363 PBIST complete A53 MPU CLUSTER0, test index 0 PBIST Functionality Test Failed. Some tests have failed.
The log for am62x example gives code 0xa6, which also corresponds to TISCI_DEV_A53SS0.

Some tests have failed.
It is to be noted that no such failure is observed in CCS (nobootmode). This issue is observed in am62x, am62px, am62ax and am62dx.
On further analysis (am62p, PBIST example), it seems all TISCI macros related to A53 core are giving failures -
TISCI_DEV_A53SS0_CORE_0 to 3, TISCI_DEV_COMPUTE_CLUSTER0 and even the PBIST device TISCI_DEV_COMPUTE_CLUSTER0_PBIST_0
