25G Link Detection Issue on LA1224-RDB-BLS with LX2160ARDB Rev2 Image

[harisankar2001]

Dear NXP Team,

I would like to provide an update regarding the issue we’re facing with the 25G link detection on the LA1224-RDB-BLS board.

Current Status:

Working Configuration: Our custom image, based on the LSDK21.08, is working correctly on the LX2160ARDB board, including 25G link detection. The interfaces are coming up as expected, and we can establish a connection without issues.

NXP Provided Image: The NXP-provided image for the LA1224RDB-BLS board works fine, including 25G link functionality, which suggests that the hardware is in good condition and capable of supporting the 25G link.

Problematic Configuration: However, when using the same custom image with a basic SDK bring-up of the LX2160ARDB Rev2 build on the LA1224-RDB-BLS board, the 25G link does not come up. The interface mapping appears correct, but we are unable to establish a connection, and the link remains inactive.

Are there any specific configurations or errata that need to be applied for the LA1224RDB-BLS board when using an image built for the LX2160ARDB Rev2?

Your expertise and guidance in resolving this issue would be greatly appreciated, as it is critical for our project timeline.

Same reply, LX2160ARDB-rev2 and  LA1224-RDB-B, the Retimers on the both boards are different, Inphi IN112525 on the LX2160ARDB-rev2, and TI “DS250DF230" on the LA1224-RDB-B. The driver would be different.

If you use LSDK LX2160ARDB-rve2 on the LA1224-RDB-B, it could not work.

Please use the LA1224 SDK on the LA1224-RDB-B to realize your development, if you don't have SW source in hand, please contact NXP local support for the LA1224-RDB-B.

LSDK2108 could not support LA1224-RDB-B.
