 In this example the target CPU is a MIPS of the type 34Kc.<br />
-It is also necessary to know if the CPU is running in ''little endian'' or ''big endian'' mode, on some TV series it can be guessed from the name of the software. You can check by enabling the service menu on the TV and look at the top most lines that indicate the software version. Both MIPS processors and ARM based CPU's are bi-endian, but are mostly run in little endian mode, especially for embedded applications.<br />
