I have an iMX6UL board, i am doing U-Boot Ram Test RAM address range start from 0x80000000 to 0x90000000. i need to find out the safe address range to perform U-boot- RAM test, because some portion of Ram is containig U-Boot. if i will perform RAM test for complete RAM then there are chances of RAM crash to avoid this i need address range to for which i can perform test.

Thank you :)

    See if you can build an instance of U-Boot that doesn't run in ram (e.g. runs directly from flash and uses cache as ram for stack etc) - then you don't need to avoid any part of ram in the test. – Murray Jensen Dec 16 '17 at 3:38
