temporary management purposes only.
UART Serial:
57600N1
Located on populated 5 pin header J5:
[o] GND
[ ] key - no pin
[o] RX
[o] TX
[o] 3.3V Vcc
Remove the SIM/button/LED cover, the WLAN button and 12 screws
holding the back plate and antenna cover together. The GPS antenna
is fixed to the cover, so be careful with the cable. Remove 4
screws fixing the antenna board to the main board, again being
careful with the cables.
A bluetooth TTL adapter is recommended for permanent console
access, to keep the router water and dustproof. The 3.3V pin is
able to power such an adapter.

WARNING!!
ISP managed firmware might at any time update itself to a version
where all known workarounds have been disabled. Never boot an ISP
managed firmware with a SIM in any of the slots if you intend to use
the router with OpenWrt. The bootloader lock can only be disabled with
root access to running firmware. The flash chip is physically
inaccessible without soldering.
Installation from OEM web GUI:
- Log in as "supervisor" on https://172.17.1.1/
- Upload OpenWrt initramfs-recovery.bin image on the
Maintenance -> Firmware page
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot
Installation from OEM ssh:
- Log in as "root" on 172.17.1.1 port 22022
- scp OpenWrt initramfs-recovery.bin image to 172.17.1.1:/tmp
- Prepare bootloader config by running:
nvram setro uboot DebugFlag 0x1
nvram setro uboot CheckBypass 0
nvram commit
- Run "mtd_write -w write initramfs-recovery.bin Kernel" and reboot
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot
Copying OpenWrt to the recovery partition:
- Verify that you are running a working OpenWrt recovery image
from flash
- ssh to root@192.168.1.1 and run:
fw_setenv CheckBypass 0
mtd -r erase Kernel2
- Wait while the bootloader mirrors Image1 to Image2
NOTE: This should only be done after successfully booting the OpenWrt
recovery image from the primary partition during installation. Do
not do this after having sysupgraded OpenWrt! Reinstalling the
recovery image on normal upgrades is not required or recommended.
Installation from Z-Loader:
- Halt boot by pressing Escape on console
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
image at 10.10.10.3
- Type "ATNR 1,initramfs-recovery.bin" at the "ZLB>" prompt
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- Sysupgrade to the OpenWrt sysupgrade image
NOTE: ATNR will write the recovery image to both primary and recovery
partitions in one go.
Booting from RAM:
- Halt boot by pressing Escape on console
- Type "ATGU" at the "ZLB>" prompt to enter the U-Boot menu
- Press "4" to select "4: Entr boot command line interface."
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
image at 10.10.10.3
- Load it using "tftpboot 0x88000000 initramfs-recovery.bin"
- Boot with "bootm 0x8800017C" to skip the 380 (0x17C) bytes ZyXEL
header
This method can also be used to RAM boot OEM firmware. The warning
regarding OEM applies! Never boot an unknown OEM firmware, or any OEM
firmware with a SIM in any slot.
NOTE: U-Boot configuration is incomplete (on some devices?). You may
have to configure a working mac address before running tftp using
"setenv eth0addr <mac>"
Unlocking the bootloader:
If you are unebale to halt boot, then the bootloader is locked.
The OEM firmware locks the bootloader on every boot by setting
DebugFlag to 0. Setting it to 1 is therefore only temporary
when OEM firmware is installed.
- Run "nvram setro uboot DebugFlag 0x1; nvram commit" in OEM firmware
- Run "fw_setenv DebugFlag 0x1" in OpenWrt
NOTE:
OpenWrt does this automatically on first boot if necessary
NOTE2:
Setting the flag to 0x1 avoids the reset to 0 in known OEM
versions, but this might change.
WARNING:
Writing anything to flash while the bootloader is locked is
considered extremely risky. Errors might cause a permanent
brick!
Enabling management access from LAN:
Temporary workaround to allow installing OpenWrt if OEM firmware
has disabled LAN management:
- Connect to console
- Log in as "root"
- Run "iptables -I INPUT -i br0 -j ACCEPT"
Notes on the OEM/bootloader dual partition scheme
The dual partition scheme on this device uses Image2 as a recovery
image only. The device will always boot from Image1, but the
bootloader might copy Image2 to Image1 under specific conditions. This
scheme prevents repurposing of the space occupied by Image2 in any
useful way.
Validation of primary and recovery images is controlled by the
variables CheckBypass, Image1Stable, and Image1Try.
The bootloader sets CheckBypass to 0 and reboots if Image1 fails
validation.
If CheckBypass is 0 and Image1 is invalid then Image2 is copied to
Image1.
If CheckBypass is 0 and Image2 is invalid, then Image1 is copied to
Image2.
If CheckBypass is 1 then all tests are skipped and Image1 is booted
unconditionally. CheckBypass is set to 1 after each successful
validation of Image1.
Image1Try is incremented if Image1Stable is 0, and Image2 is copied to
Image1 if Image1Try is 3 or larger. But the bootloader only tests
Image1Try if CheckBypass is 0, which is impossible unless the booted
image sets it to 0 before failing.
The system is therefore not resilient against runtime errors like
failure to mount the rootfs, unless the kernel image sets CheckBypass
to 0 before failing. This is not yet implemented in OpenWrt.
Setting Image1Stable to 1 prevents the bootloader from updating
Image1Try on every boot, saving unnecessary writes to the environment
partition.
Keeping an OpenWrt initramfs recovery as Image2 is recommended
primarily to avoid unwanted OEM firmware boots on failure. Ref the
warning above. It enables console-less recovery in case of some
failures to boot from Image1.

fa731838c524 cleared the forced speed in the QSGMII PCS_ALL_CH_CTL
register during probe, but this is only correct for GMACs that are not
configured with fixed-link. This prevented GMACs configured with both
phy-mode = "sgmii" and fixed-link from working properly, as discussed at
https://github.com/openwrt/openwrt/pull/3954#issuecomment-834625090 and
the comments that follow. Notably, this prevented all communication
between gmac2 and the switch on the Netgear R7800.
The correct behavior is to set the QSGMII PCS_ALL_CH_CTL register by
considering the gmac's fixed-link child, setting the speed as directed by
fixed-link if present, and otherwise clearing it as was done previously.

The routerbootparts driver dynamically discovers the location of MikroTik
partitions, but it cannot determine their size (except by extending them
up to the start of the next discovered partition).
The hard_config partition has a default size of 0x1000 in the driver,
while it actually takes 0x2000 on the hAP-ac2. Set the correct size in
the hAP-ac2 DTS.
On most devices, this isn't a problem as the actual data fits in 0x1000
bytes. However, some devices have larger data that doesn't fit in 0x1000
bytes. In any case, all devices seen so far have enough space for a
0x2000 hard_config partition before the start of the dtb_config partition.
With the current 0x1000 size:
0x00000000e000-0x00000000f000 : "hard_config"
0x000000010000-0x000000017bbc : "dtb_config"
With this patch extending the size to 0x2000:
0x00000000e000-0x000000010000 : "hard_config"
0x000000010000-0x000000017bbc : "dtb_config"
Other ipq40xx boards may need the same fix but it needs testing.

Using these config-options to customize the folders used at build-time makes these
folder settings appear in generated archive. This causes the SDK to be not
portable, as it's going to use the build-time folders on the new systems.
The errors vary from passing the build, disk out-of-space to permission denied.
The build-time settings of these folders are passed into the archive via Config.build.
The expected behavior is that the SDK acts after unpacking like these settings have
their defaults, using intree folders. So just filter these folders out when running
convert-config.pl to create Config.build.
This addresses the same issue that's fixed in the previous commit for the imagebuilder.

Also some user notice some instability with this idle frequency, solved by
setting the min frequency to 600mhz. Fix all these kind of problem by
introducing a boot init.d script that set the min frequency to 600mhz and set
the ondemand governor to be more aggressive. The script set these value only if
the ondemand governor is detected. 384 mhz freq is still available and user can

10. After the rebooting, reconnect the cable to other port (1-16) and
open the SSH connection, download the sysupgrade image to the device
and perform sysupgrade with it
11. Wait ~120 seconds to complete sysupgrade
Note:
- The uploaded image via WebUI will only be written with the length
embedded in the uImage header. If the sysupgrade image is specified,
only the kernel is flashed and lacks the rootfs, this causes a kernel
panic while booting and bootloops.
To avoid this issue, initramfs image is required for flashing on WebUI
of stock firmware.
- This device has 1x LED named as "POWER", but it's not connected to the
GPIO of SoC and cannot be controlled.
- port 17 is named as "WAN/CONSOLE". This port is for the upstream
connection and console access (telnet/WebUI) on stock firmware.
Back to stock firmware:
1. Set "bootpartition" variable in u-boot-env2 partition to "1" by
fw_setsys

The Netgear GS308T v1 is an 8 port gigabit switch. The GS310TP v1 is an 8
port POE+ gigabit switch with 2 SFP Ports (currently untested).
The GS308T v1 and GS310TP v1 are quite similar to the Netgear GS1xx
devices already supported. Theses two devices use the same Netgear
firmware and are very similar to there corresponding GS1xx devices. For
this reason they share a large portion of the device tree with the GS108T
and GS110TP with exception of the uimage magic and model and compatible
values.
All of the above feature a dual firmware layout, referred to as Image0
and Image1 in the Netgear firmware.
In order to manipulate the PoE+ on the GS310TP v1 , one needs the
rtl83xx-poe package
Specifications (GS308T)

The through holes are filled with PB-free solder which melts at 375C.
They can also be drilled using a 0.9mm bit.
Installation
------------
Instructions are identical to those for the similar Negear devices
and apply both to the GS308T v1 and GS310TP v1 as well.
-------------------
Boot initramfs image from U-Boot
--------------------------------
1. Press the Escape key at the `Hit Esc key to stop autoboot` prompt
2. Init network with `rtk network on` command
3. Load image with `tftpboot 0x8f000000
openwrt-realtek-generic-netgear_gs308t-v1-initramfs-kernel.bin` command
4. Boot the image with `bootm` command
The switch defaults to IP 192.168.1.1 and tries to fetch the image via
TFTP from 192.168.1.111.
Updating the installed firmware
-------------------------------
The OpenWRT ramdisk image can be flashed directly from the Netgear UI.
The Image0 slot should be used in order to enable sysupgrade.
As with similar switches, changing the active boot partition can be
accomplished in U-Boot as follows:
1. Press the Escape key at the `Hit Esc key to stop autoboot` prompt
2. Run `setsys bootpartition {0|1}` to select the boot partition
3. Run `savesys` followed by `boota` to proceed with the boot process

The Ubiquiti UniFi AC HD (UAP-AC-HD, UAP301) has two Ethernet ports,
labeled MAIN and SECONDARY, connected to gmac2 and gmac1, respectively.
The standard probe order results in gmac1/SECONDARY being eth0 and
gmac2/MAIN being eth1. This does not match the stock firmware, is
contrary to user expectation, causes the wrong (high) MAC address to be
used in a bridged configuration (the default for this device), and makes
the gmac2/MAIN port unusable in the preinit environment (such as for
failsafe). Until a recent patch, gmac1/SECONDARY (eth0) was not even
usable.
This reorders the ports so that gmac2/MAIN is eth0, and the now-working
gmac1/SECONDARY is eth1. eth0 has the low MAC address and eth1 has the
high; when bridged, the bridge takes on the correct low MAC address.
This matches the stock firmware. The MAIN port is usable for failsafe
during preinit.
This device does not have a switch on board, so there's no possibility
to remap ports via switch configuration. "ip link set $interface name"
is used instead, during preinit before networking is configured.

(https://source.codeaurora.org/quic/qsdk/oss/lklm/nss-gmac/tree/ipq806x/nss_gmac_init.c?h=nss
at d5bb14925861).
gmac1 is connected to the port on the device labeled SECONDARY, and is
currently eth0 but will be switched to eth1 by a subsequent patch. By
clearing the QSGMII PCS forced speed during dwmac initialization when
SGMII is in use, this port becomes usable.
This patch is upstreamable, and will be sent upstream after successful
testing in OpenWrt.
