From: Jeff Kletsky <git-commits at allycomm.com>
The GL.iNet AR750S ("Slate") is a dual-band, compact "travel router"
which has previously been supported by OpenWrt with only its NOR flash
accessible.
This ports the device to both NOR and NAND flash using the
upstream SPI NAND framework available in Linux 4.19
Device Highlights
* QCA9563 at 775 MHz
* QCA9887
* External antennas (2x)
* 128 MB DDR RAM
* 16 MB SPI NOR flash
* 128 MB SPI NAND flash
* 3x GigE ports
* USB 2 port
* microSD (USB-attached)
* One button, one switch
* I2C and serial headers
* OEM U-Boot supplies HTTP/GUI access
* Runs off 5 V supplied over microUSB
Implementation Notes
====================
Both the NOR and NAND variants boot off a NOR-based kernel,
consistent with the OEM's firmware.
The mode LEDs are
* Boot, Running power
* Failsafe 2G
* Upgrade 5G
Installation
============
Using sysupgrade
----------------
sysupgrade may be used to install a NAND image on a device running
a NAND image or a NOR image on a device running a NOR image. It is
recommended to *not* preserve config when upgrading from OEM firmware
or previous versions of OpenWrt. No supported sysupgrade path should
require "force". Transitioning from NOR to NAND can be accomplished
using U-Boot.
To glinet_ar750s-nand:
gl-ar750s OEM NAND, Self-built from OEM source NAND
To glinet_ar750s-nor:
gl-ar750s Self-built from OEM source NOR
glinet_gl-ar750s OpenWrt NOR (prior builds)
Using U-Boot
------------
The OEM U-Boot can be put into a graphical, firmware-upload mode by
holding down the button on the side of the router while applying power
and for a bit more than five seconds following with the current OEM
U-Boot. The power LED will come on, then the 5G LED will flash five
times, about once a second. When the 5G LED stops flashing and the
2G LED lights solid, the router's U-Boot will provide an upload page
at http://192.168.1.1/ Either a browser may be used to upload an image,
or a utility such as curl may be used:
curl -X POST -F gl_firmware=\@*-nand-squashfs-factory.img \
http://192.168.1.1/index.html
or
curl -X POST -F gl_firmware=\@*-nor-squashfs-sysupgrade.bin \
http://192.168.1.1/index.html
Note that NOR vs. NAND is based on the file name extension.
Serial & I2C Access
===================
Serial access is *not* required to flash or enter U-Boot recovery.
Serial is configured for 115200, 8n1. 3.3 V logic levels are compatible.
Warning: 5 V ("TTL") or RS232 levels can cause permananent damage.
The board has well-labled (unpopulated) headers for serial and I2C
along the front edge of the board (the edge with the LEDs). Looking
from the top, rear of the unit (behind Ethernet jacks)
