+# Flash / probe helper for the STM32H7S78-DK dual-boot project (macOS/Linux).
+#
+# Usage: gcc/flash.sh <boot|appli|all|probe|reset|verify>
+#
+#   boot    Flash Boot  (internal flash 0x08000000)
+#   appli   Flash Appli (external OSPI flash 0x70000000, needs the external loader)
+#   all     Flash Boot then Appli (required order)
+#   probe   Connect to the board and print device info (no write)
+#   reset   Hardware reset of the board
+#   verify  Dump 4 KB of internal and external flash to /tmp for inspection
+#
+# The STM32H7RS core sits behind access port 1 and the running firmware can
+# prevent a hot-plug connection, so every command uses "ap=1 mode=UR".
+#
+# STM32_Programmer_CLI is looked up in: $STM32_PROGRAMMER_CLI, $PATH,
+# the standalone STM32CubeProgrammer app, then the STM32CubeIDE plugin.
