DDR training failed in S32DS3.5 update14

Hello, expert

Customer reported DDR training failed S32DS3.5 update14, but this system worked before and there is no significant change in the HW.

The PHY Init seems to only pass around 50% of the time while the Diag Write and Operational tests fail 100% of the time.

I have checked the device information which customer filled, no error found.

Would you please have a look at the attached screenshots/logs and provide suggestions on what might be wrong?

Hi Yi,

Could you please provide additional information in order to investigate this further.

• You mentioned - "no significant change in the HW", is there any change? Are they using the exact same board & DRAM as before?
• What is the software setup customer is using now? (S32DS 3.5.14 + which RTD version)
• What are the versions in the working setup? (S32DS & RTD)
• DRAM part name and device configuration in DDR View, to double check the configuration

Also, it would help to see the training logs. Please set Log Level to Detailed Debug in DDR View, run the training and provide the content in Logs View, for both passing and failing cases.

Thank you,

Maria

Hello, Maria

After some investigation, found that customer had a corrupted file that was mishandling the PMIC watchdog. This was interfering with the DDR tool causing the observed failures. As soon as he replaced the corrupted file, everything works as expected.

Thanks for your support, this ticket can be closed.
