DDR Register Programming Aid (RPA) for SCFW 1.7.0

Hi

I cant find the RPA spreadsheet versions that were used to generate RAM-timings for the i.MX 8QM and i.MX 8QXP Mek boards. The version I see in SCFW 1.7.0 are:

i.MX 8QM: Version 23
i.MX 8QXP: Version 16

However I can't find any references on the publishing pages for the RPA's:
https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-8-8X-Family-DDR-Tools-Release/ta-p/...
https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX8QXP-DXP-DX-DDR-Register-Programming...
https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX8QM-DDR-Register-Programming-Aid-RPA...

I am concerned that I have to do the work twice once the new versions get released that they state to be a "have-to" for SCFW 1.7.0

My Questions:

1. Which versions of RPA spreadsheets are needed for i.MX8 QM and i.MX 8QXP/DXP on SCFW 1.7.0?
2. Are RPA spreadsheets version 15 (i.MX 8QXP/DXP) and version 22 (i.MX8 QM) compatible with SCFW v 1.7.0?
3. Is it possible to publish those RPA's?

Best Regards
Philippe Schenker

Hi Philippe,

 

For the moment the latest RPAs (aligned to SCFW 1.7.0) are not released publicly yet as the engineering teams are working with marketing on communication.  I cannot speak to the timeline or ETA when the RPAs will be released.

In the meantime, FWIW, we re-pro'd the issue why SCFW 1.7.0 does not work with the previous RPA/DCD (QXP v15). This line is the culprit:

DATA 4 0xff190000 0x00000CC8 /* DRC0 bringup */

 

Sorry for any inconvenience that this may cause you.

Regards,

Israel H.

Hi Israel,

Thanks for your information. I spent now (too much) time with that issue and I just wanted to mention for everyone else that steps by this issue, that also some other register changes not only

DATA 4 0xff190000 0x00000CC8 /* DRC0 bringup */

are needed. Just deleting that line alone is not helping (but it is necessary with some other bit-flips).

Best Regards,

Philippe

In the meantime I tried v15 (the currently released RPA) on the i.MX8QXP MEK with SCFW 1.5.1, everything works.
Used RPA: MX8QXP_C0_B0_LPDDR4_RPA_1.2GHz_v15.xlsx

I then tried the exact same values from the v15 for SCFW 1.7.0 on the same MEK which resulted in the same error I see on our hardware.

We are blocked now by this issue could you please release the new RPA's needed for SCFW 1.7.0 asap?

Thanks
