AM5718: AM571x DDR memory map of Linux SDK.

Please answer.

Can I change the load address to any address with the DDR space?

I found below declaration in ti_armv7_common.h 

#define CONFIG_SYS_LOAD_ADDR 0x82000000

#define DEFAULT_LINUX_BOOT_ENV \
"loadaddr=0x82000000\0" \
"kernel_addr_r=0x82000000\0" \
"fdtaddr=0x88000000\0" \
"fdt_addr_r=0x88000000\0" \
"rdaddr=0x88080000\0" \
"ramdisk_addr_r=0x88080000\0" \
"scriptaddr=0x80000000\0" \
"pxefile_addr_r=0x80100000\0" \
"bootm_size=0x10000000\0" \
"boot_fdt=try\0"

Hi,

You should be able to change as long as you ensure that you are not over writing anything with other.

At u-boot prompt you use printenv command to get all the addresses.

Hi, 

Below log is my printenv log. 

But I can't find. this log shows DEFAULT_LINUX_BOOT_ENV address in the previous post

I want to know infromation are mapped between 0x8000 0000  and 0x8200 0000 (kernel load address)
