    Caanoo / WIZ Howto: Wiz Usb-Ethernet With Stock Usb Cable

    Caanoo / WIZ Howto: Wiz Usb-Ethernet With Stock Usb Cable

    This looks like the kernel module is trying to dereference a structure member off a NULL pointer. Edited: The sources I used to compile the 1.1.0 version of the USBNetwork module is 'linux-2.6.24-pollux'. So it seems they have made further modifications to the kernel beyond what appears in...

    Caanoo / WIZ Howto: Wiz Usb-Ethernet With Stock Usb Cable

    Having insmod segfault for any reason is worrisome... So the reason the serial module works is because for some reason insmod doesn't segfault on it? I wonder what the difference is. They both attach to the same lf1000 driver.

    Caanoo / WIZ Howto: Wiz Usb-Ethernet With Stock Usb Cable

    Ah, that definitely won't work. It is a combination of hardware and software (Linux "USB Gadget Interface") limitations, although a USB hardware component might be capable of presenting plural "endpoints", and it could send configuration blocks that mix and match the meaning of those endpoints...

    Can you capture the corrupt/garbage dmesg output in a file on your SD card and quote it here? My only guess is that we're looking at some kernel incompatibility (g_ether was compiled for Wiz firmware 1.1.0, but if we're looking at a kernel version difference then I would also expect the insmod...

    Copy 320X240 Buffer To 240X320 Screen

    Yeah, ARM9 can have up to 8 pending writes (write-back cache). Reads however cannot be prescheduled so far as I know, and the cache line size is usually something like 32 bytes. So reading one pixel (of whatever size) every 320*size bytes guarantees that you are making a read out of different...

    Howto: Usb Serial Shell With Stock Usb Cable

    Try hitting enter a couple times, make sure you're waiting ~10 seconds or so (there is a 5sec sleep in the getty loop to make sure it doesn't spin on CPU, and getty itself only polls for CD every so often). You mentioned in another thread you downgraded your Wiz to an older firmware and haven't...

    Caanoo / WIZ Howto: Wiz Usb-Ethernet With Stock Usb Cable

    Although if you are behind NAT it is probably not a big issue, be warned if you are using telnetd on the Wiz on the open Internet that anyone out there can also telnet to your Wiz... I think busybox' dhcp client is on the Wiz already if you want to give that a try (invoke it from the NetworkUp...

    Too Much Wear From Plugging/unplugging The Usb Cable

    If you just do 'strings gp2xmenu', and look carefully, you'll see the commands the menu shells out to perform these operations.

    How To Improve Opengl Es Performance?

    I expect your floating point performance will differ depending on if you are using the archived toolchain (which does hardware floating point, "FPA"), or a toolchain designed to compile and link cleanly to the libs alaready on the Wiz (which uses VFP, and so has an ABI incompatible to VFA or...

    Caanoo / WIZ Howto: Wiz Usb-Ethernet With Stock Usb Cable

    Should be trivial, initially I was wondering if the "Network" package should be distinct from the "telnet" "ssh" or etc packages. Now that I've thought about it, probably they shouldn't be distinct...this module is really only usable by developers, regular users aren't going to want to setup a...

    Caanoo / WIZ Howto: Wiz Usb-Ethernet With Stock Usb Cable

    Excellent, Mies. The busybox 'telnetd' built-in to the Wiz wants to be run out of inetd; it takes control of stdin and stdout rather than listening on a network socket. Probably telnetd and ftpd are all that are really necessary over a private USB connection... Because you said you are...

    Wiz File Transfer (From Computer To Sd Card) Slowwwwww

    You are asking the wrong people, and I think your method of conducting "research" for your article, that being asking some web forum, is suspicious at best. But that said, my suspicion is with the lf1000 driver (software driving the Wiz's "USB client" hardware chip). The lf1000 driver is not...

    Caanoo / WIZ Wiz Software Ideas

    For my purposes, it doesn't really matter, because I am only working on the Wiz as a plaything/toy. But it does seem that the "OpenWiz" community could benefit greatly from a single and coherent set of conventions and a more friendly common operating environment (showing your apps as icons on...

    G_Ether + Rndis + Windoze

    I find the idea of hardware limitations really curious. I don't understand why hardware would care when it's all just exposed as integers...I'd expect those are just values in fields received as bits flow by...maybe this shows how much of a mystery USB low-layer functions are to most of us. :)

    Usb Serial Windows

    Yeah, that driver supports the "Bulk" protocol, which is what the g_serial driver is using with use_acm=0. When I was working on the g_serial gadget, I assumed the CDC/ACM requirements were provided by a separate kernel module, basically a kernel library, and the messages it emitted were about...

    Caanoo / WIZ Howto: Wiz Usb-Ethernet With Stock Usb Cable

    Dropbear seems to cross-compile easily for the Wiz. Having a little trouble convincing it to let me login since root has no password, and adding a 'toor' account bricks the Wiz, but I suspect I can work around that with a ssh key for regular default root...but I won't know for sure if that will...

    Caanoo / WIZ Thoughts On Wiz Usb Gadget Interface

    Probably VFAT directly on the NAND would be a mistake, unless they had implemented a software FTL ("Flash Translation Layer") like is done on PCMCIA flash (or a firmware FTL like is done on some USB flash thumb drives)...then it wouldn't be that different from VFAT-image-on-ubifs-on-NAND; in...

    Caanoo / WIZ Howto: Wiz Usb-Ethernet With Stock Usb Cable

    :) I initially started my post with an off-color complaint that no one seems to read module comments anymore. The instructions to define a CONFIG_DEV_ for specific lower layer hardware are written halfway through the module...of course I also didn't notice it until my third attempt at...

    Caanoo / WIZ Thoughts On Wiz Usb Gadget Interface

    While they are still fresh in my mind, I wanted to share some things that occurred to me after the recent g_serial.ko and g_ether.ko bits. 1) The LF1000 driver can only have one USB gadget attached to it. I think this is actually true of USB gadget hardware and device drivers in general. The...
