Hello Team,

      I change the SDRAM from MT41K256M16TW(512MiB) to MT41K512M16HA(1GB),  but the memory is still  512MiB.How to fix this issue.

U-boot  trace as follow：

U-Boot 2018.03-imx_v2018.03_4.14.78_1.0.0_ga+g72a67fc (May 12 2020 - 03:04:33 +0000)

Hello Hong Li,

The BSP Porting Guide available as part of the BSP Documentation may help with porting the BSP to your own hardware.

The documentation for the 4.14.78 BSP is available on the link below (you may need to login to download this documentation bundle)

https://www.nxp.com/webapp/Download?colCode=L4.14.78_1.0.0_LINUX_DOCS

You would need to change the RAM size for Uboot and for the Device Tree.

I hope this helps!
Regards,
