In hopes of finally ending this thread, I'll try to explain (again) what others have been saying. :) The issue is that the emulator does not emulate the GTA02 hardware, only the GTA01 hardware (and only a subset of that). While it is true that the core CPU in the GTA02 is supported by Qemu, that's insufficient -- the emulator needs to be "taught" (i.e. someone needs to write the code) how to emulate the other components in the GTA02. I suspect that to start with, you would need to emulate the flash memory subsystem in order to get past the bad block stuff (just a guess) -- but as soon as you get past that, you'll have to emulate the PMU chip used by the GTA02 (it's very different from the one in the GTA01). That assumes that the emulator already knows about the S3C2440 SoC (System-on-Chip, which is the Samsung CPU with the integrated I/O devices used in the GTA02); the GTA01 uses an older SoC which is -- you guessed it! -- not entirely compatible. The reason the emulator does not support the GTA02 is the same reason why it doesn't support all the hardware in the GTA01: the emulator was intended to be used by users developing software before the GTA01 hardware was stable enough and available for use. Since then, as others have pointed out, developing and debugging on the hardware is so much more practical that nobody has had any interest in further development of the emulator. So, the bottom line: the emulator does not, and most likely will never boot any GTA02 images. I can't help you out any further, because you haven't told anyone what it is that you need from the emulator. You say "Socket programming" -- well, you can do that on a desktop Linux system -- there is absolutely no difference in the sockets interface; it's the same kernel source code, the same C library, the same basic stuff. The SoC is even little-endian, just like a desktop system, so that shouldn't be an issue. So, at this point, if you are convinced that you need an emulator, I suggest that you look elsewhere -- the GTA02 is not the device that will meet that need. If, perhaps, you are inclined to explain a bit about your need, perhaps the very diverse (and generally very smart) group of folks on this list can offer some specific suggestions about alternatives that might permit the GTA02 to meet your needs, or if not, perhaps they know of a specific emulator and hardware device that would.
