Firmware analysis

Case study on SM48D EEPROM

• samples
  • 4 good
  • 1 with corrupt EEPROM, mostly ignored
• unk00: always 17
• name: always SM48D
• namei
  • no generally noticeable pattern
  • 0xF0000000 always set
• unk1E: Relatively small number that varies, possibly serial number
• pad22: always 0
• unk26: always 0
• unk44: always 0x55aa
• unk46: always 0xa233
• unk48: always 1
• pad4A: always 0

Generally seems that there is a structure being used which is initialized to 0. Some fields are unused, keeping them at 0. Anything beyond the structure is 0xFF

SM100TQ

SM-84UP

SM-208CQSX-Actel

ASM100FBG

Found at HSC. ASM100FBG is found in the EEPROM

http://www3.bpmicro.com/DeviceList.nsf/SocketSolutions/ASM100FBG

"BGA(100), 1.0 mm pitch"

Only supports 2 devices

SMAH48DL1

Closest I could find: SMAH20P (http://www3.bpmicro.com/DeviceList.nsf/SocketSolutions/SMAH20P)

Which is for a "PLCC(20...80)". Weird
