From fcc70be5f29872c11e3c8be36c9d3b9c0d016080 Mon Sep 17 00:00:00 2001 From: Zhihao Cheng Date: Mon, 11 Nov 2024 17:08:21 +0800 Subject: tests: ubifs_tools: fsck_tests: Add powercut+fsck+mount test Inject powercut while doing fsstress on mounted UBIFS for kinds of flashes (eg. nand, nor). This testcase mainly makes sure that fsck.ubifs can make UBIFS image be consistent on different flashes (eg. nand, nor). Because the min_io_size of nor flash is 1, the UBIFS image on nor flash will be different from nand flash after doing powercut, so we need make sure fsck.ubifs can handle these two types of flash.
