Softgun - The Software ARM

---

Softgun is a an embedded system emulator. Softgun is known to run linux blob and u-boot for the ARM-9 processors Digi NS9750, Freescale i.MX21 and Atmel AT91RM9200. Also softgun can emulate the ATMega 644 based game console "Uzebox". Softgun was written because i had to port embedded Linux to boards before i had the hardware.

Missing features:

• NS9750 BBus DMA-Controller (required for netos)
• Vector floating point unit
• Elf loader
