From fa52e5e2542883382e5bb7233ddfb8b025f932ab Mon Sep 17 00:00:00 2001 From: INAGAKI Hiroshi Date: Sun, 25 Apr 2021 17:06:03 +0900 Subject: [PATCH] realtek: add support for Panasonic Switch-M24eG PN28240K Panasonic Switch-M24eG PN28240K is a 24 + 2 port gigabit switch, based on RTL8382M. Specification: - SoC : Realtek RTL8382M - RAM : DDR3 128 MiB (Winbond W631GG8KB-15) - Flash : SPI-NOR 32 MiB (Macronix MX25L25635FMI-10G) - Ethernet : 10/100/1000 Mbps x24 + 2 - port 1-8 : TP, RTL8218B - port 9-16 : TP, RTL8218B (SoC) - port 17-24 : RTL8218FB - port 17-22: TP - port 23-24: TP/SFP (Combo) - LEDs/Keys : 7x / 1x - UART : RS-232 port on the front panel (connector: RJ-45) - 3:TX, 4:GND, 5:GND, 6:RX (pin number: RJ-45) - 9600n8 - Power : 100-240 VAC, 50/60 Hz, 0.5 A - Plug : IEC 60320-C13 - Stock OS : VxWorks based Flash instruction using initramfs image: 1. Prepare the TFTP server with the IP address 192.168.1.111 2. Rename the OpenWrt initramfs image to "0101A8C0.img" and place it to the TFTP directory 3. Download the official upgrading firmware (ex: pn28240k_v30000.rom) and place it to the TFTP directory 4. Boot M24eG and interrupt the U-Boot with Ctrl + C keys 5. Execute the following commands and boot with the OpenWrt initramfs image rtk network on tftpboot 0x81000000 bootm 6. Backup mtdblock files to the computer by scp or anything and reboot 7. Interrupt the U-Boot and execute the following commands to re-create filesystem in the flash ffsmount c:/ ffsfmt c:/ this step takes a long time, about ~ 4 mins 8. Execute the following commands to put the official images to the filesystem updatert example: updatert pn28240k_v30000.rom this step takes about ~ 40 secs 9. Set the environment variables of the U-Boot by the following commands setenv loadaddr 0xb4e00000 setenv bootcmd bootm saveenv 10: Download the OpenWrt initramfs image and boot with it tftpboot 0x81000000 0101A8C0.img bootm 11: On the initramfs image, download the sysupgrade image and perform sysupgrade with it sysupgrade 12: Wait ~ 120 seconds to complete flashing Known Issues: - 2x SFP ports are provided as combo ports by the RTL8218FB chip, but the phy driver has no support for it. Currently, only TP ports work by the RTL8218D support. Note: - "Switch-M24eG" is a model name, and "PN28240K" is a model number. Switch-M24eG has an another (old) model number ("PN28240"), it's not a Realtek based hardware. - Switch-M24eG has a "POWER" LED (Green), but it's not connected to any GPIO pin. - U-Boot checks the runtime images in the flash when booting and fails to execute "bootcmd" variable if the images are not existing. - A filesystem is formed in the flash (0x100000-0x1DFFFFF) on the stock firmware and it includes the stock images, configuration files and checksum files. It's unknown format, can't be managed on the OpenWrt. To get the enough space for OpenWrt, move the filesystem to the head of "fs_reserved" partition by execution of "ffsfmt" and "updatert". - A GPIO pin on PCA9539 is used for resetting external RTL8218B phy and RTL8218FB phy. This should be specified as "reset-gpios" property in MDIO node, but the current configuration of RTL8218B phy in the phy driver seems to be incomplete and RTL8218FB won't be configured on RTL8218D support. So, ethernet ports on these phys will be broken after hard-resetting. At the moment, configure this pin as gpio-hog to avoid breaking by resetting. Back to the stock firmware: 1. Delete "loadaddr" variable and set "bootcmd" to the original value on U-Boot: setenv loadaddr setenv bootcmd 'bootm 0x81000000' on OpenWrt: fw_setenv loadaddr fw_setenv bootcmd 'bootm 0x81000000' 2. Perform reset or reboot on U-Boot: reset on OpenWrt: reboot Signed-off-by: INAGAKI Hiroshi --- .../rtl8382_panasonic_m24eg-pn28240k.dts | 190 ++++++++++++++++++ target/linux/realtek/image/rtl838x.mk | 10 + 2 files changed, 200 insertions(+) create mode 100644 target/linux/realtek/dts-5.10/rtl8382_panasonic_m24eg-pn28240k.dts diff --git a/target/linux/realtek/dts-5.10/rtl8382_panasonic_m24eg-pn28240k.dts b/target/linux/realtek/dts-5.10/rtl8382_panasonic_m24eg-pn28240k.dts new file mode 100644 index 0000000000..1fa9d2cdc7 --- /dev/null +++ b/target/linux/realtek/dts-5.10/rtl8382_panasonic_m24eg-pn28240k.dts @@ -0,0 +1,190 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "rtl838x.dtsi" +#include "rtl83xx_panasonic_mxxeg-pn28xx0k.dtsi" + +#include + +/ { + compatible = "panasonic,m24eg-pn28240k", "realtek,rtl8382-soc"; + model = "Panasonic Switch-M24eG PN28240K"; + + aliases { + led-boot = &led_status_eco_green; + led-failsafe = &led_status_eco_amber; + led-running = &led_status_eco_green; + led-upgrade = &led_status_eco_green; + }; + + /* + * sfp0/1 are "combo" port with each TP port (23/24), and they are + * connected to the RTL8218FB.
