I'm currently trying to bring up a board based on imx sabresd quad. I have been changing the DDR3 reference to 4 memory alliance AS4C256M16D3L chips.
When we are trying to use the DDR stress test tool over USB OTG, i'm getting an error "ROM write failed" with a random register after IOMUXC_SW_PAD_CTL_GRP_DDRMODE_CTL.
In this case, the board resets.
Could it be related to a bad software configuration or an hardware issue?
