 What is GProbe?
 ===============
 GProbe is a protocol to communicate with various parts from

+How to flash?
+-------------
+To flash you need three things:
+- a flasher program that gets uploaded to the chip
+  - since it as a hexfile with multiple sections, you can convert it to .rapatch with hex2rapatch.py
+  - alternatively you can use ihex://, list the sections in json with :j and write them to gprobe:// using a script
+- a binary firmware blob that gets flashed
+- parameters (probably supplied in the gprobe script that comes with the firmware):
+  - load and start address for flasher program (0x1800 in the example)
+  - Maximum chunksize for flashing (0x200 in the example)
+  - flash address for binary blob (0x40000 in the example)
