| # | Problem | Possible reason, fix and workaround |
|---|---|---|
| 1 | Debug session freezes on DDR4 init | DDR4 init can be done only once, if the PS DDR4 was initialized then any attempt of double init, by FSBL c code or psu_init.tcl will freeze. Power cycle or hardware reset is required to clear DDR4 registers. |
