Such a mix&match would obviously only work if both OpenWrt versions/ builds are identical, and especially fail after sysupgrade upgraded the system disk on SATA 0:1. The fallback to SATA 1:1 needs to be kept for MBL Single (only has SATA 1:1) and MBL Duo with one disk inserted on SATA 1:1. To speed up booting in those cases, the unneccesarily doubled "sata init" will only be called once. (In theory it could be omitted completely since the on-flash boot script already initializes SATA to load the on-disk boot script.) Tested on MBL Duo (all possible combination of disks) and MBL Single Signed-off-by: Freddy Leitner Acked-by: Christian Lamparter --- diff --git a/target/linux/apm821xx/image/mbl_boot.scr b/target/linux/apm821xx/image/mbl_boot.scr index 062dc2725a..20e48dcef6 100644 --- a/target/linux/apm821xx/image/mbl_boot.scr +++ b/target/linux/apm821xx/image/mbl_boot.scr @@ -1,6 +1,6 @@ setenv boot_args 'setenv bootargs root=/dev/sda2 rw rootfstype=ext4' -setenv load_part1 'sata init; ext2load sata 1:1 ${kernel_addr_r} /boot/uImage; ext2load sata 1:1 ${fdt_addr_r} /boot/apollo3g.dtb' -setenv load_part2 'sata init; ext2load sata 0:1 ${kernel_addr_r} /boot/uImage; ext2load sata 0:1 ${fdt_addr_r} /boot/apollo3g.dtb' -setenv load_sata 'if run load_part1; then echo Loaded part 1; elif run load_part2; then echo Loaded part 2; fi' +setenv load_part1 'ext2load sata 0:1 ${kernel_addr_r} /boot/uImage; ext2load sata 0:1 ${fdt_addr_r} /boot/apollo3g.dtb' +setenv load_part2 'ext2load sata 1:1 ${kernel_addr_r} /boot/uImage; ext2load sata 1:1 ${fdt_addr_r} /boot/apollo3g.dtb' +setenv load_sata 'sata init; if run load_part1; then echo Loaded part 1; elif run load_part2; then echo Loaded part 2; fi' setenv boot_sata 'run load_sata; run boot_args addtty; bootm ${kernel_addr_r} - ${fdt_addr_r}' run boot_sata
