Hi, Attached are the modifications I had to make to get my PS/2 to GC keyboard adapter working properly. The adapter from "May Flash" and on the box it is called "GC Keyboard & PS Controller Adapter 2in1" (it can convert PSX joypads as well). There are two parts to the modifications: - getting the key codes from the raw data - a few changes in the key mapping The raw data was located in different nibbles as in the original code. I don't know if my adapter is different from the other keyboards/adapters, whether the data format is different in Wii mode compared to GC mode or whether the old code was simply broken. The old code for the third key does look broken: key[2] = (raw[0] << 4) & 0xFF; key[2] |= (raw[1] << 28) & 0xFF; The second statement has no effect, but if you replace "<<" by ">>", it starts making sense. Since this only makes a difference if 3 keys are pressed simultaneously, it's likely nobody noticed it, so the rest of it might still be correct. If you look at the diff, the key mapping looks totally different, but that is because I had to realign the columns; in fact there are only a few changes: 0A: scroll Lock 36: PrtSc and numpad-slash 37: numpad-star 39: semicolon 3A: apostrophe 3F: backslash 53: caps Lock cursors: 36 and listed I'm using a US/International PS/2 PC keyboard, so differences are probably not due to a PC keyboard layout difference. I am looking for someone with a different keyboard/adapter to test whether this new code works with it. And if it doesn't, if there is some way to auto-detect the keyboard type (maybe using other parts of the raw data). Bye, Maarten |

I just don't really like breaking the applications that support GC (i.e. so they don't run on normal PPC). If I get really precious about it I'm sure I could identify a 'cube from files in /proc. > On the other hand, one thing that I have in mind and could make linux > applications directly useable using the cube's framebuffer is building a = virtual > rgb framebuffer at the kernel level using the "recently" merged deferred = io > framework. Creating a virtual RGB frame buffer was my preferred solution for the 'problem' but it seemed easier to be efficient within userspace since damage tracking is easier. I had not come across Documentation/fb/deferred_io.txt before. I'll have a good read of this, having a 'real' framebuffer implementation is quite desirable to save a lot of userspace conversions. It would be a great step on the way to good X with the Xvideo extension (for efficient YUV access for decoders) which has long been my ambition. I suspect I will never actually find the time to write the Xvideo stuff though. Sigh. --=20 Daniel Thompson <da...@re...> |

It would help if applications were written to expect a fourcc code, but they aren't so you end up even in a worst situation. Maybe if the standard Linux kernel starts using a fourcc to specify a visual then we could use it in a useful way. On the other hand, one thing that I have in mind and could make linux applications directly useable using the cube's framebuffer is building a virtual rgb framebuffer at the kernel level using the "recently" merged deferred io framework.

Hi Folks I've been fiddling again looking at porting a few more frame buffer code to operate with the 'cube not-RGB frame buffer. It struck me that instead of lying about the visual reporting it with a fourcc code would be quite useful for detecting and adapting to strange pixel formats (and the resulting code could be ported to other weird hardware without conditional compilation). The attached patch shows what I have in mind. -- Daniel Thompson <da...@re...> |

You might be better off getting a Memory Card/SD adaptor (no idea how much they cost), sticking it in slot B, and copying your saves to a standard SD card. Then you should, in theory, be able to read and edit them in any computer with an SD reader. Joe |

Hello, IBM has contributed "official" paired singles support in the form of the PPC750CL CPU, so there's probably little reason to maintain the separate repository any longer. See the thread starting at <http://sourceware.org/ml/binutils/2007-08/msg00330.html>. IBM are also in the process of contributing paired singles support for GCC, but the patch hasn't been approved yet. The most recent version is posted at <http://gcc.gnu.org/ml/gcc-patches/2007-08/ msg01531.html>. Regards, Anders Montonen |

It would be great if indeed this appears to be true. In that case, three different devices (Ethernet, SD card, USB) can be connected to all three EXI busses, so the system performance would be maximized. I'll design a version of my ethernet controller to fit onto the Serial Port 2. It will be soldered onto the mainboard, so it should be usable on GC's without this connector as well (I think they just removed the connector, the pinout should still be on the mainboard). Meanwhile, if someone has a GameCube running Linux with access to the mainboard, it should be able to confirm that it is on the EXI2 bus by measuring the CS pin voltage and poking 0x0 and 0x380 to 0xCC006828 to enable/disable all CS pins on the EXI2 channel. Regarding the port name confusion: I had a look at the wrong cover :- S. That's what happens when your 'cube is disassembed. Actually, the high speed port might be very interesting as well. The pin description from YAGCD resembles that of standard SDRAM IC's. It might be possible to expand the GC ARAM. However, I haven't got a clue on how to use this in software, or what size of SDRAM is supported. Is there perhaps extra RAM in the GB Player?

Uhmm.. I think I've messed it up. 1514 is the "Serial Port 1" connector. 1520 is the "Serial Port 2" connector. So "Serial Port 1" should be EXI0 (as we know from the BBA). And "Serial Port 2" should be EXI2 from the drawings (FIG 26 and FIG 15C). Cheers, Albert |

(its even > in yagcd, god knows where i got that one from =P) In US patent 6,609,977 (now 7,134,960) there is a reference which could confirm your theory: "A multi-pin modem connector 1514 is used to connect the graphics and audio processor 114 to an external or internal modem. The boot ROM/real time clock 134 is coupled to the modem connector 1514 and shares its bus for communication with the graphics and audio processor 114." 1514 is the "Serial Port 2" connector. So that text is claiming that "Serial Port 2" is related to the EXI0 bus, where the Boot ROM is located. Cheers, Albert |

Hi, Yet another question, this time regarding the EXI hardware. My GC has got a 'serial port 2', I believe this is P8 as described in 2.4.1.2 of YAGCD. For my hardware, I'd like to use ports on different EXI channels, so each device can use its channel for 100%. Now, I'm wondering to which EXI channel/device this P8 is connected. It's not in the EXI device listing in 10.2, and I can't seem to find it enywhere else. Unfortunately, I haven't got Linux running on my 'cube yet because I'm still waiting for some hardware to build my own 'modchip' (I haven't got my BBA or PSO here in Australia where I'm staying for a few moths). Therefore, I'm not able to just measure CS and poke around in the EXI registers. Does anyone have more info? Cheers, Rob |

The current EXI driver is able to handle both "normal" EXI devices (which can answer to an exi_get_id() command) and "custom" EXI devices, like MMC/SD cards, the future USB adapter and your new SPI-based ethernet interface. "Custom" EXI devices have to be registered with an EXI identifier of EXI_ID_NONE. They will be initially matched against channel/device only. The driver probe function is responsible for checking if the device is really a matching device, and in that case it returns 0. Look at the MMC/SD card driver for example. It probes if a MMC/SD card is available by trying the card initialization sequence. If it fails, it assumes no card is there and the driver forgets about the device. This could lead to problems in the future if a driver probe sequence for one device can destroy another one. But, for now I think we can go ahead with what we have. Cheers, Albert |

I've picked up this excellent idea, and designed a schematic and PCB for this USB host interface. Links to the schematic and PCB are on the wiki: http://www.gc-linux.org/wiki/EXI:USBHostAdapter . I just have to wait for the company where I'm doing my internship at the moment to do their next PCB panel, then I can stick some of my PCB's on for free. Also, I'm currently working on a ethernet controller to replace the hard-to-get BBA. It will use Microchip's ENC28J60 SPI ethernet controller. I'm starting with the Linux driver modules, but I'm not sure how to do the probing/detection. The current EXI driver does (if I understand the source correctly): -select device -output 0x0000 (request ID) -read 16 bit ID -deselect device -if the read ID is 0 (which happens with MMC/SD cards apparently), and the device is on one of the memory cards, EXI_ID_NONE (or something) is returned, and all exi-device drivers claiming to support that ID are then probed. Now the problem is, with both the MAX3421 and the ENC28J60, 0x0000 means just 'read register 0', which could be anything (might be 0x00 after reset?). Also, both these parts do not have a 'Request ID' command, so there's no straight-forward way to probe them. So how do we identify these parts? Or could there be an easy way for the user to set the exi channel/device manually? Module parameters? What about the ethernet controller that might be used to mount the root fs? I guess there are more experienced driver programmers on this list who could tell me the way to go.

Yes, I noticed that too. > I ve ordered parts and i will make a shematic based on figure 21 (datasheet) > and the memcard pinout... Remember to wire up the irq line too. We'll need that. My biggest concern is that the controller doesn't support a 32MHz clock (according to the data sheet it supports a maximum of 26MHz), so we'll have to run the SPI bus at 16MHz, unless someone figures out how to program the EXI interface to a intermediate clock speed. I think it would be a good idea to keep all the details of this mini-project on the project's wiki. I've started a page specially for that: http://www.gc-linux.org/wiki/EXI:USBHostAdapter Cheers, Albert |
