DDR RPA tool for iMX8QM

Hi,

I'm looking for the DDR RPA (Register programming aid) tool compatible with SCFW 1.5.0 (or newer) and Linux BSP 5.4.24-2.1.0 for iMX8QM MEK. This is for a custom user (MEK) board with a new DDR part I'm trying to initialize. I plan to use the "MX8QM_B0_LPDDR4_RPA_1.6GHz_v21.xlsx" file from the DDR test tool to help generate initialization scripts.

Please share the RPA how-to info or user guide for using this tool and any gotchas for the SCFW build, etc.

Thanks for the help.

Hi rkohli2000

 

yes MX8QM_B0_LPDDR4_RPA_1.6GHz_v21.xlsx can be used for that BSP version.

Unfortunately I am not aware of user guides for using RPA tool, in general it has self-explanatory

fields. For  SCFW build one can look at below link and documentation included in  SCFW Porting Kit​

Sorry, I misunderstood the tool earlier.

I was expecting a new standalone "NXP RPA tool" that ingests the spreadsheet (MX8QM_B0_LPDDR4_RPA_1.6GHz_v21.xlsx).

Now, I see the separate Excel tabs labelled "DCD CFG file CBT" and "DCD Stress Test Script CBT".

Are these 2 tabs updated with the code I need to copy/paste to the SCFW porting kit file: packages\imx-scfw-porting-kit-1.5.0\src\scfw_export_mx8qm_b0\platform\board\mx8qm_mek\dcd\imx8qm_dcd_1.6GHz.cfg and input file for the DDR Stress test tool (.ds) respectively ?

Thanks a lot for the help.
