TDA4VE-Q1: TDA4VE rcu_preempt self-detected stall on CPU error

Part Number: TDA4VE-Q1
Other Parts Discussed in Thread: TDA4VM, TDA4VM-Q1

Hello,

I am currently performing power cycling tests on the TDA4 platform and have encountered an issue with "rcu_preempt self-detected stall." The problem occurs after approximately 1000 power cycles, where the CPU becomes unresponsive for an extended period. The logs consistently show the "rcu_preempt self-detected stall" error.

I found that there are patches available for TDA4VM related to this issue, but I have been unable to locate a corresponding patch for TDA4 echo. Could you please provide the appropriate patch for the TDA4 echo platform?dmesg.26.txt

Here is the link to the patch discussion for TDA4VM-Q1 regarding the "rcu_preempt self-detected stall" issue, as referenced in the thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1493726/tda4vm-q1-patch-for-rcu_preempt-self-detected-stall-on-cpu?keyMatch=rcu%20preempt%20self-detected%20stall%20on%20CPU&tisearch=universal_search

Notably, within the same thread, there is a mention of the TDA4 Echo platform encountering the exact same RCU stall issue. Unfortunately, the discussion did not progress to a resolved solution for the TDA4 Echo variant.

Thank you for your assistance.

Best regards

Hello.

Those are driver fixes which apply to even for TDA4VE similar to TDA4VM. There is nothing SOC specific in the patches.
Customer can use the same patches.
