Hi Team,
We have connected the AW-XM458MA-PUR module to the NXP LA1224-rdb Reference Design Board using the PCIe M.2 Key E connector on the J7 slot.
In the system image, we have configured the SERDES protocol as follows:
SRDS_PLL_PD_PLL5=1
SRDS_PRTCL_S1=19
SRDS_PRTCL_S2=5
SRDS_PRTCL_S3=2
SRDS_PLL_REF_CLK_SEL_S1=2
SRDS_DIV_PEX_S1=1
SRDS_DIV_PEX_S2=1
SRDS_DIV_PEX_S3=1
Additionally, PCIe support has been enabled in the Linux kernel, and we have attached the corresponding configuration file and pin mapping for reference.
However, we are encountering an issue where the module is not being detected when running the lspci command—no module appears in the PCIe device list.
Could you please provide guidance or troubleshooting steps to resolve this issue and get the module detected correctly?
