Part Number: AM625-Q1
Other Parts Discussed in Thread: SYSCONFIG, AM625
- We use the SysConfig tool to configure DDR memory, which generates the
k3-am62x-sk-ddr4-1600MTs.dtsidevice tree include file. - Our configuration parameters:
- Memory Frequency (MHz): 800
- Data Bus Width (per device): 8
- Read DBI: Disabled
- CL (CAS Latency): 12
Issue:
Some boards crash during memtest, specifically failing in the Solid Bits and Bit Flip test items. Adjusting CL from 9 to 12 has improved stability, but we need guidance on tuning other parameters. All remaining parameters are currently configured strictly according to the DDR chip datasheet.
Request:
Is there any official tool that can automatically scan and recommend the required parameters for SysConfig configuration? Or what is the standardized/recommended methodology to properly calibrate these DDR parameters for optimal stability on the AM625 platform?
