TCI6636 ram leveling failure

Hi there,

I have a custom board with a TCI6636 keystone 2 SOC on it. On Bank A there is 2GB of RAM connected.

The levelling is currently failing, when I read the phy status register I get the following

DDR3A PGSR0 = 0x80e00fff

Three bits here indicate leveling failures.

(23) WLAERR Reset = 0x0
Write Leveling Adjustment Error: Indicates if set that there is anerror in write leveling adjustment

(22) QSGERR Reset = 0x0
DQS Gate Training Error: Indicates if set that there is an error in DQS gate training.

(21) WLERR Reset = 0x0
Write Leveling Error: Indicates if set that there is an error in write leveling.

Is there anything I can do from software to fix these failures?
