From 7bba7ccde9cb021e24ec83f1332aafd5898e23ef Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Sat, 28 May 2022 20:56:31 -0500 Subject: [PATCH] realtek: EnGenius EWS2910P: use the mtd3 partition for root overlay The root overlay is mounted on the "rootfs_data" partition. This comes at the end of the firmware image, courtesy of mtdsplit. There is very little space left (About 1MB), which can fill up rapidly. The "firmware" and "firmware2" partitions are part of the bootloader dual firmware logic. They should contain independent, valid uImages. This leaves "jffs2-cfg" (mtd3) and "jffs2-log" (mtd4) as candidates. mtd3 is about 13.7 MB and is used by the vendor firmware to store configuration settings. It is only erased by vendor firmware during a factory reset. By naming this partition "rootfs_data", it becomes the root overlay, providing significantly more room. Even with mtdsplit wanting to create a "rootfs_data" on the firmware partition, mtd3 is used as the overlay. Rename "jffs2-cfg" to "rootfs_data", and profit from the extra space.
