From 8b0407d15d2ffc8eac341bbf2ad585cb8efd1163 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sat, 17 Feb 2024 21:16:12 +0100 Subject: [PATCH] apm821xx: MBL DUO-only: enable USB-Storage for boot from USB support it is possible to boot and run OpenWrt from an image on an USB-Stick on the MyBook Live DUO. (No, the MyBook Live Single does NOT have an USB-Port and attempts at enabling it sadly all failed... so far). To do that: First, prepare a USB-Stick by writing the raw and uncompressed OpenWRT factory image for the device onto the stick (i.e. # gunzip -c openwrt-*wd_mybooklive*-factory.img.gz > /dev/sd$XX). Then enter the u-boot via an attached TTL/CMOS 3.3V cable adapter and give the following commands a try in the: usb start; sata init ext2load usb 0:1 ${fdt_addr_r} /boot/apollo3g.dtb ext2load usb 0:1 ${kernel_addr_r} /boot/uImage setenv bootargs 'root=/dev/sdc2 rw rootfstype=squashfs,ext4 rootdelay=5' run addtty; bootm ${kernel_addr_r} - ${fdt_addr_r} Notes: - booting from USB-Sticks takes a long time! Be prepared to wait a few minutes. (~3 minutes for 4 MiB /boot/uImage file on a USB 2.0 Stick) - the bootargs part 'root=/dev/sdX2' depends on how many HDDs/SSDs are slotted in. (if none: then use sda, if one: sdb. if two: sdc) - rootdelay is important as the storage on the USB-Sticks do not show up fast enough. 5 seconds might be excessive though. - it's possible to concat these commands together in one line and write it into u-boot's "bootcmd" environment variable and save the environment to make the device to always boot from USB from then on. if you have accidentally overridden the 'bootcmd' and want to return to 'spec' enter the following commands : setenv bootcmd 'run boot_sata_script_ap2nc' saveenv Signed-off-by: Christian Lamparter --- target/linux/apm821xx/sata/config-default | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/target/linux/apm821xx/sata/config-default b/target/linux/apm821xx/sata/config-default index daff2d04bef2..7efb914885f3 100644 --- a/target/linux/apm821xx/sata/config-default +++ b/target/linux/apm821xx/sata/config-default @@ -54,3 +54,9 @@ CONFIG_PPC4xx_CPM=y CONFIG_REGULATOR_FIXED_VOLTAGE=y CONFIG_SUSPEND=y CONFIG_SUSPEND_FREEZER=y +CONFIG_USB=y +CONFIG_USB_COMMON=y +CONFIG_USB_DWC2=y +CONFIG_USB_DWC2_HOST=y +CONFIG_USB_ROLE_SWITCH=y +CONFIG_USB_STORAGE=y -- 2.30.2
