The EN751627 EcoNet subtarget consists of the EN7516 DSL SoC and the
(rare) EN7527 xPON SoC.
We currently support pci / wifi, usb and flash, but the EN751221 eth
driver is not portable to this family right now.
Zyxel EX3301-T0 is a wifi router based on the EN7516, it is a DSL SoC
but lacks the DSL port.
Installation instructions:
1. Serial access is required, stop the Zyxel bootloader.
2. Use ATENv3 https://github.com/cjdelisle/ATENv3 to unlock bootloader
3. "ATLD x" on the prompt to start a TFTP server
4. Connect ethernet cable from any lan (yellow) port on modem to a
device.
5. On your device, configure network to 192.168.1.2/30
6. On your device, send TRX file to 192.168.1.1 with name x, i.e.
tftp -p -l ./econet/tclinux -r x 192.168.1.1
7. On modem, you should see a line like this:
"Total 8022324 (0x7A6934) bytes received" note the hex value
8. "ATGU" to enter econet bootloader
9. "flash 80000 80020000 <the hex number without 0x>"
For example: flash 80000 80020000 7A6934
10. "reboot 1" -- start the system
If it boots back into the factory OS, you need to switch OS, from the
ZHAL prompt:
1. "ATCB" -- load data from flash
2. "ATCF 0" -- switch to OS 0
3. "ATBT 1" -- enable flash write
4. "ATSB" -- save data
5. "ATSR 1" -- reboot system

This patch adds support for Huawei HG2821T-U, EPON ONU and home router,
often comes with ISP service.
Specifications
==============
* SoC: Econet EN7526GT
* RAM: 512MiB DDR3L (MT41K256M16TW-107)
* Flash: 256MiB SPI NAND (TC58CVG1S3HRAIG)
* WiFi 2.4GHz: MT7592N
* WiFi 5GHz: MT7612EN
* Ethernet: builtin switch
* LED: Power, Internet, WiFi, USB
* Buttons: Reset
* UART: Serial console (115200 8n1)
* USB: 1 x USB2
* Other: Phone jack, XPON fiber port
!!! BACKUP YOUR ROM !!!
=======================
Please always have your FULL flash image backup before flashing
anything. The vendor firmware varies a lot depending on your ISP and
location. You will have a hard time finding the right regional firmware
if you don't have a backup.
Notes
=====
* Due to the target `econet` being incomplete, WiFi, DSA switch, and
many other features are not supported yet. Do not flash the image unless
you know the consquences or `econet` is declared stable.
* This device, and apparently many other devices of this platform, use
a dual-image layout. OpenWRT (with `econet` target) only uses slot A.
Slot B is not used by OpenWRT, and is applicable for dual-booting to
vendor firmware.
* If you do not use vendor firmware anymore, you can erase and reuse
anything after `configuration_b`, which gives you ~110 MiB free space.
Again, backup your flash first.
Installation
============
Within shell
------------
Note that acquiring the shell access to the vendor firmware can be a bit
tricky depending on the firmware variation. If you can't play with the
vendor firmware, boot to OpenWrt using debricking method below.
0. (Optional) Back up your flash, and / or move the vendor firmware to
slot B
1. Build and then locate the `kernel.bin` and `rootfs.bin` image files
2. Upload `kernel.bin` and `rootfs.bin` to the device (via HTTP or USB
stick), then type:
```
mtd write -f -e KernelA kernel.bin KernelA
mtd erase RootfsA
mtd write -f -r -e AppA rootfs.bin AppA
```
From bootloader
---------------
1. Build and then locate the `kernel.bin` and `rootfs.bin` image files
2. Switch device on and press a key within 3 seconds
3. Upload `kernel.bin` via TFTP as described below
4. Once the transfer has completed successfully, bootloader will give
you the file length in "Total %d (0x%X) bytes received", then type
`flash 200000 80020000 <file length hex>`
5. Upload `rootfs.bin` then flash with
`flash 600000 80020000 <file length hex>`
6. Restart the device to boot into OpenWRT
> [!IMPORTANT]
> Do not try `httpd` in the bootloader. It writes to the wrong address
and will corrupt the flash.
Debricking
==========
1. Build and then locate the `initramfs-kernel.bin` image files
2. Switch device on and press a key within 3 seconds
3. Connect to device via ethernet, set the IP address to `192.168.1.X`,
then upload the image via TFTP
`tftp 192.168.1.1 -m binary -v -c put initramfs-kernel.bin`
The file name can be anything except `tcboot.bin` or `tclinux.bin`,
they will corrupt the flash.
4. Type `jump 80020000` to boot the kernel from memory
Dual boot
=========
Use `en75_chboot` tool to switch between vendor firmware and OpenWrt. If
you are soft-locked, you can also switch the flag in the bootloader:
1. Switch device on and press a key within 3 seconds
2. Select the kernel that you wish to use:
- `memwl 80020000 30ffffff` for `KernelA` (OpenWrt)
- `memwl 80020000 31ffffff` for `KernelB` (Factory)
3. Select the rootfs, which should be the same as the kernel:
- `memwl 80020004 30ffffff` for `RootfsA` (OpenWrt)
- `memwl 80020004 31ffffff` for `RootfsB` (Factory)
3. Commit the data to flash: `flash 1e0000 80020000 8`
4. Restart the device to boot into the selected OS
MAC addresses
=============
`//configuration_a/factory.conf` contains MAC addresses, along with
other pre-configured settings. OpenWrt uses `brmac`, `internetmac`,
`APMAC`, and `APMAC_5G`, while `tr069mac`, `voipmac`, `priprotocolmac`,
and `PONMac` are not used for now.

Board name was specified incorrectly in the DT, fix.
This bug was introduced in #20580 (31f5fc8fea8931f5) which was
merged last week, and econet is still a mostly experimental target,
so it is considered unnecessary to update SUPPORTED_DEVICES.

This device has one USB2.0 port, plus ethernet, 2x wifi, ethernet, xPON
and VoIP.
Installation instructions: (Assuming root shell via SSH or serial)
1. Place OpenWrt TRX file on a USB stick formatted VFAT
2. Plug in the stick to the modem
3. Type: mtd write -f -e tclinux /mnt/usb2_sda1/<name of file>.trx tclinux
At this point, both OpenWrt and the vendor OS will be installed
because the device has space for two operating systems. Switch the OS
to boot to OpenWrt:
1. mtd readflash tmpdata 999999999 0 reservearea
2. echo -n '0' | dd of=./tmpdata bs=1 count=1 seek=397311 conv=notrunc
3. mtd write -f -e reservearea ./tmpdata reservearea
4. reboot
WARNING: While you can install with SSH alone, you need serial to use
OpenWrt on EcoNet devices because the Ethernet driver has not yet been
developed.

The Nokia G-240G-E is an xPON device with an EN7526G, 256M of
memory and 128M of flash. It has 1 USB2 port as well as phone and
ethernet but no wifi. Flashing instructions are per the typical
process using xmodem in the bootloader. This and other things
are described here: https://openwrt.org/inbox/toh/bt/g-240g-e_1
In addition, a generic image is offered, this image can be loaded
into memory from within the bootloader and launched directly. It
is recommended on the wiki of G-240G-E and other EcoNet devices
to be used for backing up the flash before flashing OpenWRT.

The SmartFiber XP8421-B is a fiber modem which is available for $20 online
and has 512MB of memory, 256MB of SPI NAND flash and 2 USB 2.0 ports in
addition to ethernet, wifi and XPON.
Because EcoNet is not currently producing evaluation boards, the XP8421-B
stands in as a convenient, low cost, off-the-shelf, representitive example
of the capabilities of the EN751221 econet processor. This is also the
example board that is included in the upstream Linux patchset.
The XP8421-B, and apparently many other devices of this platform, use a
dual-image layout. I have chosen to reuse this to support dual-boot between
OpenWRT and the factory firmware. Certain design decisions were made with
the goal of not overwriting data that is used by the factory OS.
This commit also introduces a utility for switching between OS_A and OS_B
which are used for OpenWRT and Factory OS respectively.
Flashing instructions (from bootloader):
Build and then locate the squashfs-tclinux.trx image file
Get the length of that file in hex: printf '%X\n' "$(stat -c%s the-file-squashfs-tclinux.trx)"
Connect to device with xmodem capability, e.g. picocom --send-cmd lsx -vv -b 115200 /dev/ttyUSB0
Switch device on and press a key within 3 seconds
Enter bootloader username and password: telecomadmin nE7jA%5m
Type: xmdm 80020000 <file length hex>
Quickly start xmodem and send the file, in picocom that is ctrl+a ctrl+s <paste-the-file-name> enter If the transfer fails to start, wait 30 seconds to a
minute for the bootloader prompt to return and then try the command again.
Once the transfer has completed successfully, type the following flash 80000 80020000 <file length hex>
Type go or simply restart the device to boot into OpenWRT
