This program is I2C read/write program under 8120. Usage: read command: [iaccess 1 address arg1 ] arg1: data bytes number write command: [iaccess 0 address arg1 arg2 arg3 ... ] arg1: data bytes number arg2 arg3 ...: data value Example: Write 8120 Standard EVB serial EEPROM (I2C read address 0xa9, write 0xa8) #./iaccess 0 0xa8 2 0x5 0x36 Means write 2 bytes to I2C bus, according to EEPROM support, 0x5 is offset, 0x36 is writing data. And read back the offset 0x5 to verify: #./iaccess 0 0xa8 1 0x05 #./iaccess 1 0xa9 1 Means write 1 bytes to EEPROM I2C bus to notify the offset is 0x5. Then read back using "iaccess 1".
