realtek: rtl930x: Add support for Plasma Cloud PSX8 Switch
The Plasma Cloud PSX8 Switch is a 8 port multi-GBit switch with
8x 10/100/1000/2500BaseT Ethernet ports.
Hardware:
- RTL9302C SoC
- Macronix MX25L25645G (32MB flash)
- Winbond W632GU6NB-12 (256MB DDR3 SDRAM - only 128 MB configured*)
- 2x RTL8224 4x 10m/100m/1/2.5 Gigabit PHY
- IC+ IP8008 POE+ PSE controller
The switch is powered by 54 Volts 2.77A 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 in the front panel.
*) Only 128 MB of RAM are currently configured because there were
infrequent random memory corruptions detected when using memtester with a
256 MB DT configuration. This could also be reproduced with RTLSDK.
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_psx8-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_psx8-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_psx8-initramfs-kernel.bin
* Boot loaded file:
bootm 0x84000000
