We are currently discussing the mass production of five upcoming models (including Korea<65><61>s top-tier premium flagship) based on the Hyundai Mobis V4H solution.
To ensure a successful SOP, the following CR-Core issues must be resolved and closed with the highest priority.
I have summarized the current CR-Core issues, including the I2C Stuck case, as follows.
To ensure smooth mass production, these issues must be closed.
The list is categorized by priority (1: Top).
<EFBFBD><EFBFBD> Ultrasonic sensor SPI communication issue (Jira#270), Priority 1
Current Status:
Excessive CPU load (90-95%) on Core 2 and loss of ultrasonic data.
Cause:
Core 2<><32>s ultrasonic sensor interrupt has the highest priority and takes up a large portion of processing.
Communication delays and disconnections occur due to spinlock application during inter-core SPI communication.
Performance constraints exist due to the DDR and AP connection structure.
Goal:
Achieve core load of 70-80% and ensure data integrity based on the customer<65><72>s performance measurement tool.
Customer Requirement:
Implementation of SPI multi-core support is mandatory to prevent ultrasonic data loss/delay. (Mass production is impossible if unresolved)
<EFBFBD><EFBFBD> Inquiry regarding Cortex-R52 Memory Mapping and BAR-based RAM Mirroring for SC3 Environment (Jira#1011), Priority 2
<EFBFBD><EFBFBD> I2C Communication with PMIC (Jira#943, 957), Priority 3
Status:
I have been testing with my own board for 3 days, but the issue was not reproduced.
Therefore, I started an aging test on the customer's reproduction board last Friday evening (April 10th).
I plan to visit the customer site on Tuesday afternoon (April 14th) to check the results.

2. THS (Thermal Sensor): Woody needs debugging support for this issue.
