By default we are reusing the stack provided by CFE, like it is intended
by CFE. On my WRT54GS it is located at 0x8043BF30, so a big kernel image
could overwrite it. Relocate it to a different memory region which is
still under the 8MB RAM, but in the higher area. We only need this
memory region for the stack of the loader, Linux will set up this
for its own.
Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
The boot process on a WRT54GL works the following way:
1. CFE gets loaded by the boot rom from flash
2. CFE loads the loader from the flash and gzip uncompresses it
3. CFE starts the loader
4. The loader stores the FW arguments and relocates itself to
BZ_TEXT_START (now 0x80600000)
5. The loader reads the Linux image from flash
6. The loader lzma decompresses the Linux image to LOADADDR (0x80001000)
7. The loader executes the uncompress Linux image at LOADADDR
The BZ_TEXT_START was set to 0x80400000 before. When the kernel gets
uncompressed and is bigger than BZ_TEXT_START - LOADADDR it overwrote
the loader which was currently uncompressing it and made the board
crash. Increase the BZ_TEXT_START my 2 MB to have more space for the
kernel. Even on 16MB RAM devices the memory goes till 0x80FFFFFF so this
should not be a problem.

This commit improves support for the Xiaomi Mi Router 3G originally
added in commit 6e283cdc0d
Improvements:
- Remove software watchdog as hardware watchdog now working as per
commit 3fbf3ab44f for all mt7621
devices.
- Reset button polarity corrected - length of press determines reboot
(short press) vs. reset to defaults (long press) behaviour.
- Enable GPIO amber switch port LEDs on board rear - lit indicates 1Gbit
link and blink on activity. Green LEDs driven directly by switch
indicating any link speed and tx activity.
- USB port power on/off GPIO exposed as 'usbpower'
- Add access to uboot environment settings for checking/setting uboot
boot order preference from user space.
Changes:
- Front LED indicator is physically made of independent Yellow/Amber,
Red & Blue LEDs combined via a plastic 'lightpipe' to a front panel
indicator, hence the colour behaviour is similar to an RGB LED. RGB
LEDs are not supported at this time because they produce colour results
that do not then match colour labels, e.g. enabling 'mir3g:red' and
'mir3g:blue' would result in a purple indicator and we have no such
label for purple.
The yellow, red & blue LEDs have been split out as individual yellow,
red & blue status LEDs, with yellow being the default status LED as
before and with red's WAN and blue's USB default associations removed.
- Swapped order of vlan interfaces (eth0.1 & eth0.2) to match stock vlan
layout. eth0.1 is LAN, eth0.2 is WAN
- Add 'lwlll' vlan layout to mt7530 switch driver to prevent packet
leakage between kernel switch init and uci swconfig
uboot behaviour & system 'recovery'
uboot expects to find bootable kernels at nand addresses 0x200000 &
0x600000 known by uboot as "system 1" and "system 2" respectively.
uboot chooses which system to hand control to based on 3 environment
variables: flag_last_success, flag_try_sys1_failed & flag_try_sys2_failed
last_success represents a preference for a particular system and is set
to 0 for system 1, set to 1 for system 2. last_success is considered *if*
and only if both try_sys'n'_failed flags are 0 (ie. unset) If *either*
failed flags are set then uboot will attempt to hand control to the
non failed system. If both failed flags are set then uboot will check
the uImage CRC of system 1 and hand control to it if ok. If the uImage
CRC of system is not ok, uboot will hand control to system 2
irrespective of system 2's uImage CRC.
NOTE: uboot only ever sets failed flags, it *never* clears them. uboot
sets a system's failed flag if that system's was selected for boot but
the uImage CRC is incorrect.
Fortunately with serial console access, uboot provides the ability to
boot an initramfs image transferred via tftp, similarly an image may
be flashed to nand however it will flash to *both* kernels so a backup
of stock kernel image is suggested. Note that the suggested install
procedure below set's system 1's failed flag (stock) thus uboot ignores
the last_success preference and boots LEDE located in system 2.
Considerable thought has gone into whether LEDE should replace both
kernels, only one (and which one) etc. LEDE kernels do not include a
minimal rootfs and thus unlike the stock kernel cannot include a
method of controlling uboot environment variables in the event of
rootfs mount failure. Similarly uboot fails to provide an external
mechanism for indicating boot system failure.
Installation - from stock.
Installation through telnet/ssh:
- copy lede-ramips-mt7621-mir3g-squashfs-kernel1.bin and
lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin to usb disk or wget it
from LEDE download site to /tmp
- switch to /extdisks/sda1/ (if copied to USB drive) or to /tmp if
wgetted from LEDE download site
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-kernel1.bin kernel1
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin rootfs0
- run: nvram set flag_try_sys1_failed=1
- run: nvram commit
- run: reboot
Recovery - to stock.
Assuming you used the above installation instructions you will have a
stock kernel image in system 1. If it can be booted then it may be used
to perform a stock firmware recovery, thus erasing LEDE completely. From
a 'working' LEDE state (even failsafe)
Failsafe only:
- run: mount_root
- run: sh /etc/uci-defaults/30_uboot-envtools
Then do the steps for 'All'
All:
- run: fw_setenv flag_try_sys2_failed 1
- run: reboot
The board will reboot into system 1 (stock basic kernel) and wait with
system red light slowly blinking for a FAT formatted usb stick with a
recovery image to be inserted. Press and hold the reset button for
around 1 second. Status LED will turn yellow during recovery and blue
when recovery complete.

TP-Link Archer C20 v1 is a router with 5-port FE switch and
non-detachable antennas. It's very similiar to TP-Link Archer C50.
Also it's based on MediaTek MT7620A+MT7610EN.
Specification:
- MediaTek MT7620A (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- 8x LED (GPIO-controlled*), 2x button, power input switch
- 1 x USB 2.0 port
* WAN LED in this devices is a dual-color, dual-leads type which isn't
(fully) supported by gpio-leds driver. This type of LED requires both
GPIOs state change at the same time to select color or turn it off.
For now, we support/use only the blue part of the LED.
* MT7610EN ac chip isn't not supported by LEDE. Therefore 5Ghz won't
work.
Factory image notes:
These devices use version 3 of TP-Link header, fortunately without RSA
signature (at least in case of devices sold in Europe). The difference
lays in the requirement for a non-zero value in "Additional Hardware
Version" field. Ideally, it should match the value stored in vendor
firmware header on device.
We are able to prepare factory firwmare file which is accepted and
(almost) correctly flashed from the vendor GUI. As it turned out, it
accepts files without U-Boot image with second header at the beginning
but due to some kind of bug in upgrade routine, flashed image gets
corrupted before it's written to flash. So, to flash this device we must
to prepare image using original firmware from tp-link site with uboot.
Flash instruction:
Until (if at all) TP-Link fixes described problem, the only way to flash
LEDE image in these devices is to use tftp recovery mode in U-Boot.
There are two ways to flash the device to LEDE:
1) Using tftp mode with UART connection and original LEDE image
- Place lede-ramips-mt7620-ArcherC20-squashfs-factory.bin in tftp
server directory
- Configure PC with static IP 192.168.0.66/24 and tftp server.
- Connect PC with one of LAN ports, power up the router and press
key "4" to access U-Boot CLI.
- Use the following commands to update the device to LEDE:
setenv serverip 192.168.0.66
tftp 0x80060000 lede-ramips-mt7620-ArcherC20-squashfs-factory.bin
erase tplink 0x20000 0x7a0000
cp.b 0x80060000 0x20000 0x7a0000
reset
- After that the device will reboot and boot to LEDE
2) Using tftp mode without UART connection but require some
manipulations with target image
- Download and unpack TP-Link Archer C20 v1 firmware from original web
site
- Split uboot.bin from original firmware by this command (example):
dd if=Archer_C20v1_0.9.1_4.0_up_boot(160427)_2016-04-27_13.53.59.bin of=uboot.bin bs=512 count=256 skip=1
- Create ArcherC20V1_tp_recovery.bin using this command:
cat uboot.bin lede-ramips-mt7620-ArcherC20-squashfs-factory.bin > ArcherC20V1_tp_recovery.bin
- Place ArcherC20V1_tp_recovery.bin in tftp server directory.
- Configure PC with static IP 192.168.0.66/24 and tftp server.
- Connect PC with one of LAN ports, press the reset button, power up
the router and keep button pressed for around 6-7 seconds, until
device starts downloading the file.
- Router will download file from server, write it to flash and reboot.

by the request to update the MIB counter is cleared.
This commit removes the get_port_stats() code introduced in 4d8a66d and
leaves a note for future hacker's beware.

The addresses were read from the 'config' partition, which would not always
contain the addresses at the same offsets, depending on the stock firmware
version used before flashing LEDE. Change this to get the addresses from
the 'product-info' partition, which is read-only.
