Panasonic Switch-M8eG PN28080K is a 8 + 1 port gigabit switch, based on
RTL8380M.
Specification:
- SoC : Realtek RTL8380M
- RAM : DDR3 128 MiB (Winbond W631GG8KB-15)
- Flash : SPI-NOR 32 MiB (Macronix MX25L25635FMI-10G)
- Ethernet : 10/100/1000 Mbps x8 + 1
- port 1-8 : TP, RTL8218B (SoC)
- port 9 : SFP, RTL8380M (SoC)
- 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: pn28080k_v30000.rom)
and place it to the TFTP directory
4. Boot M8eG 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 <official image>
example:
updatert pn28080k_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 <imagename>
12: Wait ~ 120 seconds to complete flashing
Note:
- "Switch-M8eG" is a model name, and "PN28080K" is a model number.
Switch-M8eG has an another (old) model number ("PN28080"), it's not a
Realtek based hardware.
- Switch-M8eG has a "POWER" LED (Green), but it's not connected to any
GPIO pin.
- The U-Boot checks the runtime images in the flash when booting and
fails to execute anything in "bootcmd" variable if the images are not
exsisting.
- 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".
- On the other devices in the same series of Switch-M8eG PN28080K, the
INT pin on the PCA9555 is not connected to anywhere.
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

v1 -> v2:
- drop changes for kernel 5.4
- add interrupt-related properties to the nodes of PCA9539 and PCA9555
- use "gpio-keys" instead of "gpio-keys-polled"
- update/remove comments in mtd partitions
- use "led-*" scheme and add color/function properties for each node of
LEDs
- drop unnecessary default values from gpio-restart node
v2 -> v3:
- move interrupt related properties in PCA9539 to device dts
- move child i2c bus definitions in PCA9545 to device dts
- use actual SoC name "rtl8380" in second compatible of root
v3 -> v4:
- drop unnecessary "/delete-node/" of rtl8231 from dtsi
