I’m using the memory characterization tools to generate a cfg file for a board with lpddr3, and have a question about the tBKV step. I’ve got all the numbers that TegraK1_MemoryCharacterization_AppNote_DA07217003v02.pdf say I need, and the procedure runs like it should.
However, I noticed that tbkv.py parses t35_LPDDR3_DDR3L_tflight.xls. This is a file that contains delays for both PKG and PCB. The guide mentions nothing about this document, and I have no idea what data to input for PCB. The numbers already in there for Jetson do not resemble the board delays in TK1_DDR_Board_Delay.xlsx.
From debugging it seems that tbkv.exe uses the textfiles created from t35_LPDDR3_DDR3L_tflight.xls, so I suspect they have some relevance.
Can anyone shed a little light on this?
