The '''CAT-DEV''' ('''Cafe Tool for Development; Product Code: WUT-001''') was the main development system for the Wii-U.

The CAT-DEV features all the ports and functionality found on a retail system (minus the disk drive), as well as 2 additional USB ports, three additional Wired RF serial ports, an internal hard drive, and in later versions a LAN Port. The CAT-DEV System can be configured to be in one of several boot modes.

The typical development flow using a Cat-DEV is to plug it into the network, and run "cafeon", or "caferun" from the Cafe SDK to emulate a full filesystem on the host PC.

In "PCFS", or "DUAL" mode the MION will not power on the actual Cafe OS until a HTTP Request is received to power on the underlying OS.

One of the services exposed by the MION is telnet, which requires a username, and password. The username is "mion", and the password is: "/Multi_I/O_Network/" (this username/password can also be used on the web interface). Although the telnet doesn't seem to expose anything incredibly useful, it is possible to get logs from the MION board itself, as opposed to the logs coming from CafeOS. This username/password is consistent across all known versions of MION Firmwares, and seems to be added on every boot even if it's removed.

The CAT-DEV (Cafe Tool for Development; Product Code: WUT-001) was the main development system for the Wii-U. It can come in black, white, or tan/gold colors in a small rectangular box depending on the version. Most CAT-DEV's will be 'beige' which is most commonly used for the later final revisions. Each CAT-DEV including full Wii-U hardware with 4Gbs of RAM (the retail system contained only 2Gbs of RAM), as well as a Debugger, Optical Disc Emulation, and Host I/O Hardware. Later revisions also contained an internal HDD. The CAT-DEV features all the ports and functionality found on a retail system (minus the disk drive), as well as 2 additional USB ports, three additional Wired RF serial ports, an internal hard drive, and in later versions a LAN Port. The CAT-DEV System can be configured to be in one of several boot modes. The boot mode recommended in many of the SDK Docs requires a host system attached, along with a network connection for both the CAT-DEV, and the Host PC running the associated SDK. Each SDK version only has a certain documented list of CAT-DEV's supported. The typical development flow using a Cat-DEV is to plug it into the network, and run "cafeon", or "caferun" from the Cafe SDK to emulate a full filesystem on the host PC. Developers could add, and remove directories dynamically to add titles and directories. Debug output is usually streamed over the network connection, but can also be gathered over a USB-Serial connection.

There are also Latte B1X CAT-DEVs (or at least IOSU has support for that configuration), but it's not clear if they were distributed externally or not.

CAT-DEV EV

The CAT-DEV EV (also known as the CAFE EV, EV board or just EV) was a variant of the CAT-DEV used internally at Nintendo. It probably had additional debug features similar to the NDEV1; socketed chips, JTAG connectors, external clock connectors, etc.

There's also an "EV_Y" variant which was introduced with Latte A5X/CAT-DEV MP2.

Boards

Known CAT-DEV MP2 Wii-U versions: WUP-DEV-X8, WUP-DEV-X9, and WUP-DEV-X10.

MION: "CATHDD-X5"

Serial Port Settings

Baud Rate: 57600

       termios.c_cflag = (termios.c_cflag & !libc::CSIZE) | libc::CS8;

       termios.c_cflag = termios.c_cflag & !libc::PARODD & !libc::PARENB;

       termios.c_cflag &= !libc::CSTOPB;

MION

The CAT-DEV's from V3 onwards started featuring a "MION" board (short for "Multi I/O Network") that contained the internal hdd of the later units, as well as is the device that managed the LAN port connection. It is the real brains of driving the power, serial output, and filesystem (in certain boot modes) for the CAT-DEV. When developers are interacting with the CAT-DEV through tools in the SDK like "cafeon", "findbridges", etc. They're actually interacting with the MION board directly. There are three boot modes available on MION CAT-DEVs: "PCFS", "DUAL", and "HDD Reader Mode". HDD Reader Mode is the only mode that allows the actual Cafe OS, and "wii-u" portion to boot when first receiving power. In "PCFS", or "DUAL" mode the MION will not power on the actual Cafe OS until a HTTP Request is received to power on the underlying OS. In many cases you must also spin up several TCP, and UDP services for the device to interact with, but every known MION has a series of flags you can set to force booting when 'PCFS' is turned on. MIONs are also how developers would 'find' the cat-dev on a network since there was no visual indicators when first powering them on. They did this through UDP Broadcast packets on port 7974. They also have support for fetching the internal memory, and disk state (although only 512 bytes at a time).

One of the services exposed by the MION is telnet, which requires a username, and password. The username is "mion", and the password is: "/Multi_I/O_Network/" (this username/password can also be used on the web interface). Although the telnet doesn't seem to expose anything incredibly useful, it is possible to get logs from the MION board itself, as opposed to the logs coming from CafeOS. This username/password is consistent across all known versions of MION Firmwares, and seems to be added on every boot even if it's removed. The MION has the following known Versions:
