ASmedia Pcie to SATA controller - Samsung 860 EV0 SSD -EMEM address decode error

we have connected the Jetson tx2 pcie port to IDT switch and one of the switch port we have connected ASMedia pcie to sata card and on the sata port connected samsung 860 EVO (SSD) .

In lspci we have detected the SATA controller but not detected on /dev/sda.

Please guide us in what all configuration need to be chosen in order to avoid this error.

What is the software version being used here?
I think the issue here seems to be that this particular endpoint doesn’t support 64-bit MSI and supports only 32-bit MSI, but looks like the system has allocated a 64-bit MSI target address, which resulted in EMEM address decoding error.
I think you are using r28.2 or older. If that is indeed the case, please apply below patch to solve the issue.

Thanks for your info. Now Iam unable to detect SSD and device is shown as /dev/sda .

But when Iam trying to create a file system ext4 on it Iam getting this error.
