Details:

For the following queue buffers in VPAC and DMPAC UTC, UTC may hang or experience data corruption when ECC error injection is enabled through software control to collect diagnostics.

Memory Name of affected queue buffers:

• dru_utc_vpac_tpram_dru_queue_buffer
• dru_utc_vpac_tpram_dru_queue_buffer2
• dru_utc_dmpac_tpram_dru_queue_buffer
• dru_utc_dmpac_tpram_dru_queue_buffer2

Workaround(s):

Software must disable ECC injection on the aforementioned QUEUE memories to avoid causing UTC to hang.

Note: ECC check will still be functional during normal operation.
