Hi.
Today, I noticed Linux fails to mount initramdisk
on my boards.
I found I could solve the issue by reverting the following commit:
commit c2e7e72bb9f0cb47d024997b381cb64786eb5402
Author: Rick Altherr <raltherr at google.com>
Date: Wed Jan 18 17:12:24 2017 -0800
bootm: relocate ramdisk if CONFIG_SYS_BOOT_RAMDISK_HIGH set
I have not figured out the detail yet.
The boot log is like this:
