Display apparatus and method for updating micom code thereof

A method for updating a micom code in a display apparatus which includes a micom storing a system code and a CPU, the method comprising:

• receiving a micom code by the CPU;
• updating the micom code installed in the micom using the received micom code by the CPU;
• and
• if an error occurs while the CPU updates the micom code, driving the CPU using the system code from the micom,
• wherein the micom comprises:
• a storage unit which stores the system code for driving the CPU,
• wherein the storage unit comprises:
• a boot code area which stores the system code for driving CPU;
• a flash ROM area which records micom codes for operating the display apparatus;
• and
• a check area in which a check code indicating whether the micom code is normally recorded in the flash ROM area is recorded,
• wherein the driving the CPU comprises:
• checking whether a check code is recorded normally in the check area at a time of rebooting the system by the micom;
• and
• driving the CPU using the system code by the micom if the check code is not recorded normally,
• wherein driving the CPU further comprises:
• if the CPU is operated using the system code, restarting updating the micom code after deleting the check area and the flash ROM area.

A system which updates a micom code, the system comprising:

• a micom which stores a micom code and a system code;
• and
• a Central Processing Unit (CPU) which receives another micom code and updates the micom code installed in the micom using the received other micom code,
• wherein, if an error occurs while the CPU updates the micom code installed in the micom with the received other micom code, the micom drives the CPU using the system code stored in the micom
• wherein the micom comprises:
• a storage unit which stores the system code for driving the CPU,
• wherein the storage unit comprises:
• a boot code area which stores the system code for driving a CPU;
• a flash ROM area which records micom codes for operating the display apparatus;
• and
• a check area in which a check code indicating whether the micom code is normally recorded in the flash ROM area is recorded,
• wherein the driving the CPU comprises:
• checking whether a check code is recorded normally in the check area at a time of rebooting the system by the micom;
• and
• driving the CPU using the system code by the micom if the check code is not recorded normally,
• wherein driving the CPU further comprises:
• if the CPU is operated using the system code, restarting updating the micom code after deleting the check area and the flash ROM area.
