[Petalinux 2021.1] SATA link down

Jump to solution

Hi,

I have found SATA always link down issue when kernel is up with petalinux 2021.1 and there is no problem with petalinux 2020.2.

Here are two boot log. How do I fix this issue?

In U-boot, sata works fine

There are difference between 2020.2 device tree and 2021.1 device tree. I have referred the link sata_device_tree and modify my sata reference clock to 150 MHz. Now, sata works fine.

 

Thanks
