i.MX6SX PCIe RX Termination

cstiegman123 — Wed, 10 May 2023 16:49:34 GMT

Is there a way to confirm the setting of the i.MX6SX PCIe RX Termination. I am seeing PCIe RX SI results for a PCIe implementation on an i.MX6SX that possibly indicate the RX termination is set to OFF and I am looking for a way to confirm. The PCIe PHY registers are not memory mapped, and I’m not sure if the controller is changing the settings.

Hi,

Thank you for your interest in NXP Semiconductor products.

I'm afraid that there is no other way than using commands as section 47.5.3 in i.MX 6 SoloX Reference Manual states. As the PHY was an external device, it has to be accessed using commands.

You could verify it reading the written settings to double check.

Regards
