Flash instructions:
************************************************************************
NOTE: serial access is required! Although the web UI allows you to
install the Openwrt image, secure boot is enabled which will prevent
booting an unsigned image. The boot sequence must be adjusted in U-boot
to allow booting unsigned images.
************************************************************************

1. On OEM firmware, login to the web UI (typically @ http://192.168.1.1)
and click 'CA' in the bottom right corner.
Then click -> Connectivity -> Manual Upgrade.
Alternatively, browse to
http://<router IP>/fwupdate.html.
Upload openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.ubi.
Continue with step 5.
2. Installation on alternate partition using serial connection from OEM
firmware (default login: root, password: admin):
flash_erase /dev/mtd19 0 0
nandwrite -p /dev/mtd19 openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.ubi
reboot
Continue with step 5.
3. Installation using serial connection from initramfs
setup tftp server listening on IP in 192.168.1.0/24 (other than the
router IP 192.168.1.1). In U-boot, load the initramfs image to memory:
tftp $loadaddr <your IP>:openwrt-qualcommax-ipq50xx-linksys_mx6200-initramfs-uImage.itb
boot the image using command:
bootm $loadaddr
when fully booted, scp the sysupgrade image to your router IP (default:
192.168.1.1):
scp -O <path>/openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-sysypgrade.bin [email protected]:/tmp/
use sysupgrade to flash the image to nand:
sysupgrade -n -v /tmp/openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-sysupgrade.bin
Continue with step 5.
4. Optionally install on alternate partition. From Openwrt:
mtd -r -e rootfs_1 -n write openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.ubi rootfs_1
Continue with step 5.
5. Setup U-boot for ability to dual boot signed (stock) and non-signed
(Openwrt) images with auto-detection.
From U-boot, run (be aware: copy line by line):
setenv setnandbootargs 'setenv bootargs init=/sbin/init ubi.mtd=rootfs rootfstype=squashfs rootwait'
setenv nandinitcmd 'setenv mtdids nand0=nand0; run setrootfscmd; ubi part rootfs 2048'
setenv setrootfscmd 'if test $boot_part = 1; then setenv mtdparts mtdparts=nand0:0x${imgsize}@0x${prikern}(rootfs); else setenv mtdparts mtdparts=nand0:0x${imgsize}@0x${altkern}(rootfs); fi'
setenv readhdr1cmd 'ubi read $loadaddr kernel 0x40; setexpr IMGOFF $loadaddr + 0x10; setexpr CODEOFF $loadaddr + 0x14; setexpr SIGOFF $loadaddr + 0x1c; setexpr CERTOFF $loadaddr + 0x24'
setenv readhdr2cmd 'setexpr.l HDR *$loadaddr; setexpr.l IMGSZ *$IMGOFF; setexpr.l CODESZ *$CODEOFF; setexpr.l SIGSZ *$SIGOFF; setexpr.l CERTSZ *$CERTOFF; setexpr TSIZE $CODESZ + $SIGSZ; setexpr TSIZE $TSIZE + $CERTSZ'
setenv testmbncmd 'if test $HDR -ne edfe0dd0 -a $IMGSZ -eq $TSIZE; then bootipq; else ubi read $loadaddr kernel $kernsize; run setnandbootargs; bootm $loadaddr; fi'
setenv bootcmd2 'if test $auto_recovery = no; then bootipq; else run nandinitcmd; run readhdr1cmd; run readhdr2cmd; run testmbncmd; fi'
setenv bootcmd 'run bootcmd2'
saveenv
6. Back to the OEM firmware.
Download firmware from OEM website:
MX6200: https://support.linksys.com/kb/article/408-en/
From serial/SSH, in Openwrt, flash OEM firmware to alternate partition:
mtd -r -e rootfs_1 -n write FW_MX6200_1.0.11.216041_prod.signed.img rootfs_1

Switching active partition:
1. From U-boot, executive the following to switch to partition 1:
setenv boot_part 1
for partition 2:
setenv boot_part 2
2. From Openwrt:
fw_printenv boot_part
In case it's 1:
fw_setenv boot_part 2
. /lib/upgrade/platform.sh
linksys_bootconfig_set_primaryboot "0:bootconfig" 1
linksys_bootconfig_set_primaryboot "0:bootconfig1" 1
In case it's 2:
fw_setenv boot_part 1
. /lib/upgrade/platform.sh
linksys_bootconfig_set_primaryboot "0:bootconfig" 0
linksys_bootconfig_set_primaryboot "0:bootconfig1" 0
and
reboot
