From 7f7bf36ec5bacbf414615d3cde009be548a86ae0 Mon Sep 17 00:00:00 2001 From: Alexander Couzens Date: Tue, 1 Jun 2021 21:09:26 +0000 Subject: [PATCH] ramips: add support for minew g1-c The minew g1-c is a smart home gateway / BLE gateway. A Nordic nRF52832 is available via USB UART (cp210x) to support BLE. The LED ring is a ring of 24x ws2812b connect to a generic GPIO (unsupported). There is a small LED which is only visible when the device is open which will be used as LED until the ws2812b is supported. The board has also a micro sdcard/tfcard slot (untested). The Nordic nRF52832 exposes SWD over a 5pin header (GND, VCC, SWD, SWC, RST). The vendor uses an older OpenWrt version, sysupgrade can be used via serial or ssh.
