From 0974a9f2001aeffca853f41db50ab1fff52e61f8 Mon Sep 17 00:00:00 2001 From: SangYoun Kwak Date: Thu, 11 Jul 2024 20:46:50 +0900 Subject: [PATCH] scripts: sd_fusing: Fix to write both a/b partition If sd_fusing script is executed with '--update ab' option, it should write images to both a/b partitions. When writing images, first, script reads image and writes to the partition a until the image reaches the end. Next, script reads image and writes to the partition b but it uses same file object so there is nothing left to read. Thus, script writes nothing to the partition b. To fix this issue, a method call of the file object ".seek(0)" is added before writing to the partitions. This will set cursor to the initial position and the the image can be written to the partition b.
