Subject: [Buildroot] [PATCH RESEND] imx/genimage: Place the rootfs at a proper offset when BR2_LINUX_KERNEL_INSTALL_TARGET=y
Date: Sat, 13 Nov 2021 11:38:57 -0300 [thread overview]
Message-ID: <20211113143857.2741808-1-festevam@gmail.com> (raw)
Currently, when BR2_LINUX_KERNEL_INSTALL_TARGET=y is selected, issuing
a "saveenv" command in the U-Boot prompt may lead to rootfs corruption.
Avoid this problem by placing the rootfs at an 8MB offset, just like
it is done in genimage.cfg.template.
Tested on a imx6qp-wandboard and also on a custom imx6ull based board.
"saveenv" does not corrupt the rootfs anymore after this change.
