Hi There,
We plan to use the LS1043A for in Automotive use.
Use SerDes with SRDS_PRTCL_S1 = 9960.
(A:PCIe(x1)、B:PCIe(x1)、C/D:PCIe(x2))
I want to run an SSD module (PCIex4) with SerDes C/D.
I have some questions on the "LS1043A".
1.Are SerDes C = lane0 and SerDes D = lane1 correct ?
2.Does the PCI controller support 2-lane operation ?
(SSD module (PCIe x 4))
Best regards

[NXP] LNmGCR0[FIRST_LANE] --> Indicates the lane is the first (lane 0) of a group of lanes. For the 0x9960 protocol, you will see the value for Lane C as 1'b1 indicating lane 0 of the link, whereas, for lane D, the value will be 1'b0, indicating NOT lane 0 of the link.

[NXP] Yes, it should work assuming SSD is connected via the SATA-PCIe interface.
