8051 Architecture

1. Lets play with ITE IT8502E embedded controller firmware from Vostro V13 laptop It is available here

2. Find datasheet for this chip and open firmware with radare2:

r2 -a 8051 ite_it8502.rom

3. 8051 firmware have simple and flat structure, so it starts from the beginning:

[0x0000000]> pd 1
     ,=< 0x0000000      02002e     ljmp 0x2e

So go to the start function at 0x2e addr:

[0x0000000]> s 0x2e; pd 10
