+Subject: [PATCH] tests: upcase_table: use dd/printf instead of truncate and
+ xxd -r
+
+The upcase_table test scripts used `truncate` (coreutils) and
+`xxd -r - <file>` to build and corrupt the test image. In minimal
+images (e.g. Yocto core-image-minimal + BusyBox) `truncate` is often
+absent and BusyBox's `xxd` applet does not implement the two-operand
+`xxd -r - <file>` revert form, so the scripts fail with:
+
+  truncate: command not found
+  FAIL: to create corrupted image
+
+Every xxd/truncate use here reduces to "size the image to 32 MiB" and
+"write one constant byte at a computed offset", both of which `dd`
+(with printf for the byte value) does portably with tools already
+present in a base rootfs.
+
+Upstream-Status: Submitted [https://github.com/exfatprogs/exfatprogs]
