SATA Low Speed Issue on LS1012ARDB with Debian Server Image

kami — Mon, 10 Feb 2025 01:20:14 GMT

I am trying to use an SSD with the LS1012ARDB, but the SATA speed is limited to ~43 MBps.
The system is running a Debian server image, and the OS boots from an SD card.

Despite trying various approaches, I cannot achieve full SATA speed.

My question is:

Does FlexBuild configure any default settings that could be limiting SATA performance?
Are there any recommended patches or configurations to improve SATA performance?

Thanks in advance!

Got information from the LSDK team, just as stated by UG10143, LS1012ARDB has not do the full test, it works on the LS1012ARDB with basic bootup, and no plan to do the full test further.

https://docs.nxp.com/bundle/UG10143/page/topics/release_notes.html

But you could refer to Layerscape Linux Distribution POC User Guide Rev, L6.1.36_2.1.0, which have done the full test.

Thanks
