Dear Renesas Team.
We are using custom RZ/A1H board, we are able to boot the board using internal 10MB of RAM, but if if try to boot from external SD-RAM of 64MB i.e from etron, the board is not booing it is trowing the below error.

u-boot Booting Linux...
to boot from SD-RAM, i'am following the bewlo seteps
1)change the address in .dtb file memory@20000000 {
device_type = "memory";
reg = <0x0C000000 0x04000000>;
};
2)change physical address 0x0C000000 by tying ./build.sh kernel menuconfig
3)build the kernel completely
4)run xsa_command to boot from SD-ram
this is the environment set in my u-boot
