+to the flash of an esp32. The test application can be used
+for unit tests or for general debugging of the ULP.
+
+It requires the serial port that the esp32 is connected to.
+Requires that esptool.py is installed.
+
+Example:
+ulp-forth flash_test /dev/tty.usbserial-0001`,
+	Run: func(cmd *cobra.Command, args []string) {
