adrv9025 dpd error code

Hi ADI:

We have problems about enable 4 path DPD.(4 streams for 4 Tx channels are used.)

When we enable 4 path DPD ,the dpd status shows the error code : 0x340a、0x340e or 0x341d,

0x340a: DPD AM AM outliers error,0x340e: LDL solver error,0x341d: DPD stability error

How to prevent theses error code?

P.S. DPD status in single Tx channel operation is okay

Many Thanks
