Hi,

I am looking like to know about DDR configuration and its validation procedure. I am new to the IMX8dx.We have custom boards with 1GB with 2 DDR , new board will have only 1 DDR for 1GB.

As looking in u-boot/Linux for DDR configuration, later with this community got to know, SCU will handle the DDR.

DDR configuration is having this excell sheet : MX8M_DDR3L_register_programming_aid_VAL_preliminiary_v1_2.xlsx apart from this any script is needed ?? if so where i can get it that script to generate code.

Please help in this.

Hi,

DDR Stress test is working fine. We have HW issues , that we have been fixed.

scu fw tool kit only little bit confuse state, as we going to use different IDE which is not in the list, so which source need to be considered for porting into our IDE from the list of Software components (Linux, QNX, FreeRTOS, KSDK).

Please guide.
