Arria 10 : data abort after DDR calibration

Hello,

I am designing Linux OS for our custom board based on Arria 10 SoC.I have build uboot and peripheral rbf image and uploaded them in SD card.In our custom board we have used DDR3 memory at HPS side.

While booting, the console is showing a data abort and prefetch error after DDR calibration:

U-Boot 2014.10 (Sep 19 2019 - 11:13:27)

CPU : Altera SOCFPGA Arria 10 Platform

BOARD : Altera SOCFPGA Arria 10 Dev Kit

I2C: ready

DRAM: WARNING: Caches not enabled

FPGA: writing ghrd_10as066n2.periph.rbf..

SF: Detected N25Q1024A with page size 256 Bytes, erase size 4 KiB, total 128 MiB

DDRCAL: Success

INFO : Skip relocation as SDRAM is non secure memory

Reserving 2048 Bytes for IRQ stack at: ffe3a6e8

Wdata abort

Could anyone please suggest how to remove this error?

Thanks,
