realtek: add support for Linksys LGS352C Hardware specification ---------------------- * RTL9311 SoC, 2 MIPS Interaptiv cores @ 1000MHz * 512MB DRAM * 2MB NOR Flash * 128MB NAND Flash * 48 x 10/100/1000BASE-T ports * 4 x 10G SFP+ ports * LM63 controlled fan * Power LED, Fault LED * Reset button on front panel * UART (115200 8N1) via RJ45 Installation using serial interface ----------------------------------- 1. Press "a" "c" "p" during message "Enter correct key to stop autoboot" 2. Start network "rtk network on" 3. Load image "tftpboot <TFTP IP>:openwrt-realtek-rtl931x_nand-linksys_lgs352c-initramfs-kernel.bin" 4. Boot image "bootm" 5. Switch to first bootpartition "fw_setsys bootpartition 0" 5. Download sysupgrade "scp <IP>:openwrt-realtek-rtl931x_nand-linksys_lgs352c-squashfs-sysupgrade.bin /tmp/." 6. Install sysupgrade "sysupgrade /tmp/openwrt-realtek-rtl931x_nand-linksys_lgs352c-squashfs-sysupgrade.bin" Installation using OEM webinterface ----------------------------------- This is not possible because the OpenWrt NAND Flash layout is different from the vendor layout. To be precise. Vendor uses: - 64 MB vendor UBI root_data - 32 MB vendor kernel+root 1 (~19 MB used) - 32 MB vendor kernel+root 2 (~19 MB used) OpenWrt uses: - 64 MB vendor UBI (not touched) - 10 MB OpenWrt kernel - 22 MB Openwrt mtd-concat UBI - 23 MB vendor kernel 2 (space reduced, vendor data unchanged) - 09 MB OpenWrt mtd-concat UBI Dual-boot with stock firmware using writable u-boot-env ------------------------------------------------------- From stock to OpenWrt / primary image 1 (CLI as admin): - > boot system image1 - > reboot From OpenWrt to stock / boot image 2: (shell as root) - # fw_setsys bootpartition 1 - # reboot Debrick using serial interface ------------------------------ 1. Press "a" "c" "p" during message "Enter correct key to stop autoboot" 2. Load vendor image with "upgrade runtime <TFTP IP>:LGS352xxxxx.imag" 3. switch to primary partition "setsys bootpartition 0" 4. safe config "savesys" Further documentation --------------------- See https://openwrt.org/toh/linksys/lgs352c
