+Genpix SkyWalker-1 firmware probe and dump tool.
+
+The SkyWalker-1 uses a Cypress FX2 (EZ-USB) microcontroller.
+FX2 devices support reading internal RAM (8KB at 0x0000-0x1FFF)
+and external RAM via standard vendor requests:
+  - bRequest=0xA0 (FX2 firmware load/read)
+  - wValue=address, wIndex=0
+
+This tool also queries Genpix-specific vendor commands to gather
+device info before attempting a firmware dump.
