Python/Linux port of Psychson, a tool to modify firmware of Phison 2251-03 aka 2303 (BadUSB)

• download and decompress psycholin
• download Psychson and copy all source files (*.h and *.c) in patch/ and firmware/ and the whole templates/ directory
• install sdcc, sg3-utils and binutils
• use psychsolin like Psychson

• python 2.7
• sdcc
• sg3-utils (sg_raw)
• binutils (objcopy)
• bash

• all names are lower case (e.g. psychsolin/drivecom equals Psychson/DriveCom)
• python modules are called directly (e.g. to call drivecom you call python psychsolin/drivecom instead of tools/DriveCom.exe)
• parameters are passed Linux style (e.g. python psychsolin/drivecom --action=GetInfo instead of tools/DriveCom.exe /action=GetInfo)
• tools not included (see Dependencies)

• only 11 sections of the firmware are dumped by drivecom --action=DumpFirmware, so if the flashed firmware uses more than 11 of the 16 possible sections the dump is incomplete; it's unknown why Psychson does it that way, but psychsolin does it also that way in case it's to avoid bricking the device
• (i)peek and (i)poke in drivecom console mode don't work
