- POWER: 12VDc 2A
The device comes in two variants depending on where the bootloader
loads the kernel. One variant where the bootloader loads at 0xbc140000
(mtd4), and another at 0xbe800000 (mtd5). This patch is for the latter.
I haven't found a way to change this behavior, so I'm making a
distinction between the two.
This is the MTD partitions from the stock firmware:
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"
0x000000140000-0x000002800000 : "ubiconcat0"
0x000002800000-0x000002c00000 : "kernel"
0x000002c00000-0x000007f00000 : "ubiconcat1"
0x000007f00000-0x000007f80000 : "configbak"
0x000000000000-0x0000079c0000 : "ubi"
I have the mtd5 variant on hand, and will send another patch for the
other variant once I confirmed some flash offsets, or update this
patch when a way could be found to set this load address.
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:
(RX) (GND) (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 to load.
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
The only configurable LEDs are the red and white data, and white wifi
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.
There is also an exported GPIO to reset the WWAN. These are also 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, and implemented a patch in part that achieves '2Gbps CPU
bandwidth', found here: https://github.com/openwrt/openwrt/pull/10238
