Subject: [PATCHv2] ramips: add support for Notion R281
Notion R281 is a Cat.6 LTE CPE. It is known as Boosteven R281 in some
markets.
Product link: https://www.notioni.com/productinfo/759146.html
Hardware highlights:
- CPU: MT7621A 2C4T @ 880MHz
- RAM: DDR3 128MB @ 1066MHz
- FLASH: S34ML01G2 128MB SPI NAND
- WLAN0: MT7603E 2.4GHz 802.11bgn 2x2:2 @ 300Mbps
- WLAN1: MT7613BE 5GHz 802.11nac 2x2:2 @ 867Mbps
- SWITCH: MT7530 4-port GbE
- WWAN: Marvell PXA1826 (Nezha3) Profile M26H Board Cat.6 LTE
- SIM: 1x Mini-SIM 2FF
- USB: 1x USB 2.0 Micro Type-B
- BUTTONS: WPS, Reset
- LEDS: Power, Data, Wi-Fi, LAN, Signal1-3
- POWER: 12VDc 2A
The device comes in two configurations. In one configuration the
bootloader loads the kernel at 0xbc140000 (mtd4) and another at
0xbe800000 (mtd5). This patch is for the former. To check, gain root
shell and run 'cat /proc/cmdline', look for 'root='. If
'root=/dev/mtdblock5' then it is already configured as intended. If not,
then run
fw_setenv bootargs console=ttyS1,57600n8 root=/dev/mtdblock5
in the terminal, or run
setenv bootargs console=ttyS1,57600n8 root=/dev/mtdblock5
in U-boot. Reboot then follow the installation instructions below.
This is the flash layout for the mtd4 configuration:
0x000000000000-0x000007f80000 : "ALL"
0x000000000000-0x000000080000 : "Bootloader"
0x000000080000-0x000000100000 : "Config"
0x000000100000-0x000000140000 : "Factory"
0x000000140000-0x000002800000 : "firmware1"
0x0000002d6867-0x000002800000 : "rootfs"
0x000000b00000-0x000002800000 : "rootfs_data"
0x000002800000-0x000004ec0000 : "firmware2"
0x000004ec0000-0x000007f00000 : "ota"
0x000007f00000-0x000007f80000 : "Configbak"
This is the flash layout for the mtd5 configuration:
0x000000000000-0x000007f80000 : "ALL"
0x000000000000-0x000000080000 : "Bootloader"
0x000000080000-0x000000100000 : "Config"
0x000000100000-0x000000140000 : "Factory"
0x000000140000-0x000002800000 : "firmware1"
0x000002800000-0x000004ec0000 : "firmware2"
0x000002996dfc-0x000004ec0000 : "rootfs"
0x000003180000-0x000004ec0000 : "rootfs_data"
0x000004ec0000-0x000007f00000 : "ota"
0x000007f00000-0x000007f80000 : "Configbak"
This is how it looks when flashed to OpenWrt with this patch:
0x000000000000-0x000000080000 : "u-boot"
0x000000080000-0x0000000a0000 : "u-boot-env"
0x000000100000-0x000000140000 : "factory"
0x000000140000-0x000000540000 : "kernel"
0x000000540000-0x000007f00000 : "ubi"
0x000007f00000-0x000007f80000 : "configbak"
Installation Instructions:
Stock firmware runs an old OpenWrt Chaos Calmer release. Unfortunately,
because of the changes in the flash layout, this cannot be sysupgrade-d
readily from stock. Installation will be via tftpboot in the bootloader.
Connect the USB-TTL serial converter as follows, indicated on the board
by the APTX marking near three round PCB pads:
(GND) (RX) (TX) APTX
Baud rate is 57600.
1. Connect the computer to the device via ethernet cable. Set a static
adddress of 10.10.10.3/24 to the wired interface.
2. Start the TFTP server, point it to where the initramfs image is
located. Rename the image to 'test.bin'.
3. Turn on the device. There will be a three-second delay before the
default 'Boot system code via flash' is selected.
4. Interrupt the boot process by pressing 1 to 'System Load Linux to
SDRAM via TFTP'.
5. Press enter to accept the default 'Input device IP (10.10.10.123)'.
6. Press enter to accept the default 'Input server IP (10.10.10.3)'.
7. Press enter to accept the default 'Input Linux Kernel filename ()',
or enter 'test.bin'.
8. Wait for the initramfs image to finish loading.
9. Reconnect the wired interface to any LAN ports of the device via
DHCP.
9. Flash the sysupgrade image at
http://192.168.1.1/cgi-bin/luci/admin/system/flash
What Works?
- LEDs
- Buttons
- Wired LAN and WAN
- Wireless LAN
What Doesn't?
- Wireless WAN
The only configurable LEDs are the red and white data, and white Wi-Fi
LEDs. I use the red data LED as status indicator for OpenWrt. The white
LAN LED is controlled by the switch and functions as expected, as well
as the three green signal LED indicators controlled by the WWAN. I setup
the WPS button to work as a Wi-Fi/rfkill button. There is also an
exported GPIO to reset the WWAN. These are the same LEDs and GPIO found
on the stock firmware.
Support for WWAN could come at a later date. I have setup LAN1 of the
device as WAN.

Hi,
The white spaces in this patch are damaged. Please send it again with
git send-email for example.
