From 401d8c7051c395d93bdc8a931020b348d7d297fd Mon Sep 17 00:00:00 2001 From: Valerio 'ftp21' Mancini Date: Sun, 27 Aug 2023 00:01:58 +0200 Subject: [PATCH] uboot-mediatek: add initial Zyxel EX5601-T0 support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Flash procedure is described in next commit. TLDR: Copy preloader and uboot to /tmp and write them in the mtd. This will also require new UBI partition and volumes to boot openwrt. mtd write /tmp/openwrt-mediatek-filogic-zyxel_ex5601-t0-ubootmod-preloader.bin bl2 mtd write /tmp/openwrt-mediatek-filogic-zyxel_ex5601-t0-ubootmod-bl31-uboot.fip fip Changelist: - Added profile for 4k+256 SPI NAND_TYPE - Added basic Zyxel EX5601-T0 uboot profile Backported from hitech95 branch: - Button RESET pin fix - Button WPS pin fix Signed-off-by: Valerio 'ftp21' Mancini Signed-off-by: Nicolò Veronese (cherry picked from commit a9cf87027e75c9798bf3cb683a7c32985e4ea483) ---
