> Subject: [PATCH v2 2/2] board: imx8mm: add boot.cmd for distro boot on > iMX8MM > > From: Alice Guo <alice....@nxp.com> > > Distro Boot requires a U-Boot-specific script named boot.scr or boot.scr.uimg > which contains boot commands to boot the system. The boot.cmd is such a > file. Use mkimage to generate boot.scr or boot.scr.uimg from boot.cmd, and > the command is: > mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Distro Boot Script" -d > boot.cmd boot.scr.uimg > > The boot.cmd file is an example script and can be modified based on needs. > bootargs is set in this script and root uses the default value " > /dev/mmcblk1p2 rootwait rw" which can be changed by overriding mmcroot. > > Signed-off-by: Alice Guo <alice....@nxp.com> > --- > > Changes for v2: > - add the additional explanation of boot.cmd in commit message > > board/freescale/imx8mm_evk/boot.cmd | 35 > +++++++++++++++++++++++++++++ > 1 file changed, 35 insertions(+) > create mode 100644 board/freescale/imx8mm_evk/boot.cmd > > diff --git a/board/freescale/imx8mm_evk/boot.cmd > b/board/freescale/imx8mm_evk/boot.cmd > new file mode 100644 > index 0000000000..fdfceec263 > --- /dev/null > +++ b/board/freescale/imx8mm_evk/boot.cmd > @@ -0,0 +1,35 @@ > +setenv bootargs console=${console} root=${mmcroot}; > + > +for boot_target in ${boot_targets}; > +do > + if test "${boot_target}" = "mmc1" ; then > + if fatload mmc 1:${mmcpart} ${kernel_addr_r} ${image}; > then > + if fatload mmc 1:${mmcpart} ${fdt_addr} > ${fdt_file}; then > + echo Load image and .dtb from SD > card(mmc1); > + booti ${kernel_addr_r} - > ${fdt_addr}; > + exit; > + fi > + fi > + fi > + > + if test "${boot_target}" = "mmc2" ; then > + if fatload mmc 2:${mmcpart} ${kernel_addr_r} ${image}; > then > + if fatload mmc 2:${mmcpart} ${fdt_addr} > ${fdt_file}; then > + echo Load image and .dtb from > eMMC(mmc2); > + booti ${kernel_addr_r} - > ${fdt_addr}; > + exit; > + fi > + fi > + fi > + > + if test "${boot_target}" = "dhcp" ; then > + if dhcp ${kernel_addr_r} ${serverip}:${image}; then > + if dhcp ${fdt_addr} ${serverip}:${fdt_file}; > then > + echo Load image and .dtb from > net(dhcp); > + booti ${kernel_addr_r} - > ${fdt_addr}; > + exit; > + fi > + fi > + fi > + > +done > --
