Other Parts Discussed in Thread: TDA4VM
Hello TI experts,
I have a question about LPDDR4 Vref value for TDA4VM SOC.
We can set DDRSS_CTL_180 register to program DDR MR14 register. So DDR Vref can be defined by it. However, the DDR Vref training function is also enabled. Register DDRSS_PI_61 is 10020101. Then I'm confused about what is the actual LPDDR4 Vref value.
Questions:
1.How to get the actual LPDDR4 Vref value?
2. Is it always changing when DDR works, or is it only adjusted once during DDR initializes?
