TDA4AL-Q1: How to make MCU2_0 call UART to output data.

Part Number: TDA4AL-Q1

Hi,

 We use SDK version 8.6.The autosar system is configured on MCU1_0 and MCU2_1. The Linux system is deployed on core A.
 We currently require MCU2_1 to generate log outputs. Upon reviewing the chip manual, it was discovered that only MCU1_0/1 utilize the UATR of the MAIN Domain. We have also consulted Linux for UART initialization guidance. Nevertheless, log outputs are still not being produced.
Q:
Does Linux and MCU2_1 experience preemption when outputting logs?
How does MCU2_1 use which UART to print information for logging?
