Previous RAM dumps via 0xA0 vendor request turned out to be live FIFO
data, not firmware - the Genpix FX2 firmware overrides the standard
0xA0 handler. Discovered that I2C_READ (0x84) with wValue=0x51 and
wIndex=offset reads the boot EEPROM directly.
EEPROM contents (Cypress C2 format):
- VID:PID 09C0:0203, config 0x40 (400kHz I2C)
- 9,472 bytes of 8051 firmware in 10 load records
- Code range 0x0000-0x24FF, entry at LJMP 0x188D
- Ghidra auto-analysis finds 61 functions
Tools: eeprom_dump.py (full dump), eeprom_probe.py (I2C protocol discovery)
