    I'd say the shellshock thread answers that question.



    Any luck on the datasheet front?

    At this point I think the most helpful thing would be tracking down more of the datasheets and tracing the pin outs of the main chips. Even the less technically inclined can help in that area.

    True. On that I'd be curious how the thing behaves with the chip removed. Does it try to boot from somewhere else (hard drive)? JTAG might be an option for poking at the chip too, assuming it's...

    If we had the lines of the chip it should be possible to dump it with an SD reader as has been done with the consoles that have eMMC chips. I do have a heat gun that could pop the chip off easy...

    Probably not news to most but J3200 is the serial. Pin 1 is TX, 2 is GND, 3 appears to be RX. You can connect to it with an FTDI cable, MicroFTX or similar. Settings are 115200 8N1. Output on...

    It looks like the HD ships blank on the Roamios so the OS must be contained on the eMMC. Anyone have the equipment to pop that off so we can trace out CLK/CMD/DAT lines for dumping?

    You're right on the top left. Sata, Sata power, and a fan. Two connectors on the bottom left and right wire up to the LEDs. When pulling it apart I don't remember seeing any unpopulated headers,...

    The Series5 (Tivo Roamio) Development Thread

    Figure a new thread will keep from the Premiere information/efforts and the Roamio efforts getting intertwined. Here are some high res pics of the PCB. They're a but slanted and blurry in a couple...

    The best I've run across so far are these, but they are rather blurry.

    Perhaps, before this thread gets muddled, a new thread for Roamio efforts is in order? If/When I get my hands on a Roamio...

    Hard to say that. Given the S4 wasn't hacked the S5 could be very similar security wise or it could be a completely new implementation. Really until someone has their hands on it and starts tearing...

    I'd be curious to see some high resolution pics for any of the premieres. With and without chips removed, or one's that have traces annotated.

    It's been a while since I've read through the thread, but the problem with threads this long is they aren't really great at organizing the information. For discussion sure.

    I hadn't tried using netperf, but in doing so it did end up narrowing down the cause. The one scenario I hadn't tested was the specific port the tivo was hooked up to. It turned out that it the...

    Transfer Speed Issues

    I've got two promed TivoHD's. For the last few months they've worked well. Extracting off either with tyftpd yielded speeds around 2.5MB/s. As of about a week ago, though, one of them dropped to...
