From 96c2119dbaf3cc137d963c00035386934b7ed6e8 Mon Sep 17 00:00:00 2001 From: Michael Pratt Date: Sun, 22 Jan 2023 03:21:53 -0500 Subject: [PATCH] ath79: add support for Senao Engenius ESR1750 FCC ID: A8J-ESR1750 Engenius ESR1750 is an indoor wireless router with a gigabit ethernet switch, dual-band wireless, internal antenna plates, and a USB 2.0 port **Specification:** - QCA9558 SOC 2.4 GHz, 3x3 - QCA9880 WLAN PCIe mini card, 5 GHz, 3x3 - QCA8337N SW 4 ports LAN, 1 port WAN - 40 MHz clock - 16 MB FLASH MX25L12845EMI-10G - 2x 64 MB RAM - UART at J1 populated, RX grounded - 6 internal antenna plates (omni-directional) - 5 LEDs, 1 button (power, 2G, 5G, WAN, WPS) (reset) **MAC addresses:** Base MAC address labeled as "MAC ADDRESS" MAC "wanaddr" is similar to "ethaddr" eth0 *:58 MAC u-boot-env ethaddr phy0 *:58 MAC u-boot-env ethaddr phy1 *:59 --- u-boot-env ethaddr +1 WAN *:10:58 u-boot-env wanaddr **Serial Access:** RX on the board for UART is shorted to ground by resistor R176 therefore it must be removed to use the console but it is not necessary to remove to view boot log optionally, R175 can be replaced with a solder bridge short the resistors R175 and R176 are next to the UART RX pin **Installation:** Method 1: Firmware upgrade page NOTE: ESR1750 might require the factory.bin for ESR1200 instead, OEM provides 1 image for both. OEM webpage at 192.168.0.1 username and password "admin" Navigate to Settings (gear icon) --> Tools --> Firmware select the factory.bin image confirm and wait 3 minutes Method 2: TFTP recovery Follow TFTP instructions using initramfs.bin use sysupgrade.bin to flash using openwrt web interface **Return to OEM:** MTD partitions should be backed up before flashing using TFTP to boot openwrt without overwriting flash Alternatively, it is possible to edit OEM firmware images to flash MTD partitions in openwrt to restore OEM firmware by removing the OEM header and writing the rest to "firmware" **TFTP recovery:** Requires serial console, reset button does nothing at boot rename initramfs.bin to 'uImageESR1200' make available on TFTP server at 192.168.99.8 power board, interrupt boot by pressing '4' rapidly execute tftpboot and bootm **Note on ETH switch registers** Registers must be written to the ethernet switch in order to set up the switch's MAC interface. U-boot can write the registers on it's own which is needed, for example, in a TFTP transfer. The register bits from OEM for the QCA8337 switch can be read from interrupted boot (tftpboot, bootm) by adding print lines in the switch driver ar8327.c before 'qca,ar8327-initvals' is parsed from DTS and written. for example: pr_info("0x04 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD0_MODE));
