From c7059c56a85567ce6bc943960168b19e2572508b Mon Sep 17 00:00:00 2001 From: Shiji Yang Date: Fri, 20 Jan 2023 03:16:33 +0000 Subject: [PATCH] ath79: improve support for Letv LBA-047-CH 1. Convert wireless calibration data to NVMEM. 2. Enable control green status LED and change default LED behaviors. The three LEDs of LBA-047-CH are in the same position, and the green LED will be completely covered by the other two LEDs. So don's use green LED as WAN indicator to ensure that only one LED is on at a time. LED Factory OpenWrt blue internet fail failsafe && upgrade green internet okay run red boot boot 3. Reduce the SPI clock to 30 MHz because the ath79 target does not support 50 MHz SPI operation well. Keep the fast-read support to ensure the spi-mem feature (b3f9842330) is enabled. 4. Remove unused package "uboot-envtools". 5. Split the factory image into two parts: rootfs and kernel. This change can reduce the factory image size and allow users to upgrade the OpenWrt kernel loader uImage (OKLI) independently. The new installation method: First, rename "squashfs-kernel.bin" to "openwrt-ar71xx-generic-ap147-16M-kernel.bin" and rename "rootfs.bin" to "openwrt-ar71xx-generic-ap147-16M-rootfs-squashfs.bin". Then we can press reset button for about 5 seconds to enter tftp download mode. Finally, set IP address to 192.168.67.100 and upload the above two parts via tftp server.
