Other Parts Discussed in Thread: TDA4VM, TDA4VL, TDA4VH, DRA829
There is a known errata for J721E/TDA4VM/DRA829 where connecting a PCIe switch, or multi-function PCIe device would cause a system abort. This issue only affects J721E/TDA4VM/DRA829 and does not affect similar devices such as TDA4VH/TDA4VL. For convenience, posting errata documentation, of which errata i2086 is of interest: https://www.ti.com/lit/er/sprz455d/sprz455d.pdf
Logs would look like the following:
