DRA821U: Errata i2160 workarround

one and zero

Part Number: DRA821U
Other Parts Discussed in Thread: TDA4VM

Hi Champs,

is the assumption correct that “Jacinto7_DDRSS_RegConfigTool“ would produce the register settings (e.g. k3-j721e-ddr-evm-lp4-4266.h) to address errata i2160 - so additional setting of registers would be required, correct?

Thanks and kind regards,

The values that the Jacinto7_DDRSS_RegConfigTool (version 0.5.0) outputs for PI_CALVL_VREF_INITIAL_START_POINT_F* and PI_CALVL_VREF_INITIAL_STOP_POINT_F* are hard-coded based on the values used during TDA4VM characterization. These do not necessarily correspond to any recommendation reported in errata i2160 of SPRZ455 (December 2020).
