LPDDR2 Script aid for imx6sl 512 MB dram

I'm trying to run a ddr calibration test for an imx6slevk board with 512 MB lpddr2 Dram.

I found a script aid in this link: i.MX6SL LPDDR2 Script Aid  however in the comments below, it is mentioned that this scripts is not compatible for 512 Mb Ram.

I tried going through the reference manual and looked at each of the registers mentioned in the .inc file but none of them mention the size.

Can anyone tell me what changes I need to make in the script for 512 MB ram?


I tried booting the board after making changes in the imximage.cfg file but the board doesn't flash beyond u-boot.

These were the logs:



U-Boot 2017.03-imx_v2017.03_4.9.88_2.0.0_ga+gb76bb1b (Sep 26 2019 - 11:25:23 +0530)

CPU: Freescale i.MX6SL rev1.2 996 MHz (running at 792 MHz)
CPU: Commercial temperature grade (0C to 95C) at 43C
Reset cause: POR
Model: Freescale i.MX6 SoloLite EVK Board


Even the DRAM size isn't printing now.
