From f84371ddb5163f38bd0a5fb390522455cbff7cec Mon Sep 17 00:00:00 2001 From: Harshal Gohel Date: Mon, 14 Apr 2025 13:16:47 +0000 Subject: [PATCH] realtek: rtl930x: Add support for Plasma Cloud MCX3 Media Converter The Plasma Cloud MCX3 Media Converter is a 3 port multi-GBit switch with 2x 10/100/1000/2500BaseT Ethernet ports and 1x SFP+ module slot. Hardware: - RTL9302C SoC - Macronix MX25L25645G (32MB flash) - Winbond W632GU6rB-11 (256MB DDR3 SDRAM) - RTL8224 4x 10m/100m/1/2.5 Gigabit PHY - IC+ IP802AR POE+ PSE controller The media converter is powered by 54 Volts 1.2A barrel connector. The internal TTL serial connector can be used to access the terminal. Pins from 1: TX RX (unused) GND. Serial connection is via 115200 baud, 8N1. A reset button is accessible through a hole next to the SFP+ module slot. Installation ------------ * The device can be flashed by using sysupgrade command. Either from the original vendor firmware or using an initramfs (see "Debug") * Connect serial as per the layout above. Connection parameters: 115200 8N1 * The image must be copied using scp to /tmp of the device scp openwrt-realtek-rtl930x-plasmacloud_mcx3-squashfs-sysupgrade.bin root@[IP address of the device]:/tmp/ * start sysupgrade without saving the original vendor configuration sysupgrade -n /tmp/openwrt-realtek-rtl930x-plasmacloud_mcx3-squashfs-sysupgrade.bin Installation via u-boot ----------------------- If you have an TFTP server connected to the switch, it is possible to directly install the device using the factory image from u-boot # setup networking and IP of TFP server rtk network on setenv ipaddr 10.100.100.99 setenv serverip 10.100.100.20 # get factory image tftp 0x84000000 factory.bin # erase firmware partitions sf probe 0 sf erase 0x100000 0x01f00000 # write firmware to both partitions sf write ${fileaddr} 0x100000 ${filesize} sf write ${fileaddr} 0x1080000 ${filesize} # adjust the boot commands setenv bootargs "mtdparts=spi0.0:896k(u-boot),64k(u-boot-env),64k(u-boot-env2),15872k(inactive),15872k(firmware2)" setenv bootcmd "rtk init; bootm 0xb5080000" # restart reset Debug ----- * Connect serial as per the layout above. Connection parameters: 115200 8N1. * A tftp server is required, tftpd-hpa works well. * Power the device, at U-Boot start rapidly hit Esc key to stop autoboot * Enable network: rtk network on * Change ip address of device: setenv ipaddr 192.168.1.6 * Download initramfs from TFTP server: tftpboot 0x84000000 192.168.1.111:openwrt-realtek-rtl930x-plasmacloud_mcx3-initramfs-kernel.bin * Boot loaded file: bootm 0x84000000 Signed-off-by: Harshal Gohel Signed-off-by: Sven Eckelmann Link: https://github.com/openwrt/openwrt/pull/20625 Signed-off-by: Robert Marko --- .../realtek/base-files/etc/board.d/02_network | 1 + .../base-files/lib/upgrade/platform.sh | 1 + .../upgrade/upgrade_dualboot_plasmacloud.sh | 2 + .../realtek/dts/rtl9302_plasmacloud_mcx3.dts | 210 ++++++++++++++++++ target/linux/realtek/image/rtl930x.mk | 6 + 5 files changed, 220 insertions(+) create mode 100644 target/linux/realtek/dts/rtl9302_plasmacloud_mcx3.dts diff --git a/target/linux/realtek/base-files/etc/board.d/02_network b/target/linux/realtek/base-files/etc/board.d/02_network index d5d60f6936..5a9757969a 100644 --- a/target/linux/realtek/base-files/etc/board.d/02_network +++ b/target/linux/realtek/base-files/etc/board.d/02_network @@ -68,6 +68,7 @@ realtek_setup_macs() lan_mac_end=$(macaddr_add $lan_mac $((mac_count2-mac_count1))) ;;
