31	Hardware and U-Boot firmware / Hardware / Re: Firmware CRC load error when loading upa or wlan firmware	on: January 17, 2011, 08:08:31 PM
I did read all of the posts. Yours clearly states that you want to go back and forth from AP and client mode and you are using an Ionics Stratus Zigby rather than a Guruplug. I only want client mode on a guruplug. I'm not a software engineer either. I did try the command to reset uap8xxx but it gave a file not found error. Now I see that this has to happen in the startup scripts before the module is unloaded. I was working from commandline. I am trying to be methodical and reproduce the steps others took to fix the problem. Now my startup scripts are a jumbled mess from all of the wifi client fixes I tried to implement. Could someone update the wifi client fix wiki page? The default patchfiles (provided from an older kernel version build) aren't compatible with a clean 2.6.33.7 kernel (I got missing macro definition errors) and none of this reseting stuff is in there. It may save someone else from wasting a lot of time.

I want to only use my plug as a wireless client so I followed the instructions http://www.openplug.org/plugwiki/index.php/Setting_GuruPlug_to_be_a_stable_WiFi_Client to flash the fixed 2.6.33.7 kernel and install the 2.6.33.7 modules and the wireless files. I am unable to get the wireless client module to work. When I try to do this Quote * Next, you can install the new drivers in the following order: insmod /root/mcypt.ko insmod /root/sd8xxx.ko You should get the following output: mcypt: module license 'Marvell Proprietary' taints kernel.

I followed the kernel building instructions here http://www.openplug.org/plugwiki/index.php/Re-building_the_kernel_and_U-Boot except I used the 2.6.37 kernel source from here http://sheeva.with-linux.com/sheeva/ and I applied the patchset from here http://www.openplug.org/plugwiki/images/c/c6/Guruplug-patchset-2.6.33.2.tar.bz2 The libertas_uap code is in the patchset The netdev_for_each_mc_addr macro seems to be part of recent kernel sources http://tomoyo.sourceforge.jp/cgi-bin/lxr/ident?i=netdev_for_each_mc_addr but I don't know if the author of the wificlient fix wikipage used another version of kernel 2.6.33.7. I haven't checked the Marvell git repository version of 2.6.33.7 yet.

I'm following the instructions here to build a custom kernel so that I can use my guruplug server plus as a wifi client http://www.openplug.org/plugwiki/index.php/Setting_GuruPlug_to_be_a_stable_WiFi_Client I followed the instructions to cross compile a 2.6.33.7 kernel with the fixes but I get an error when trying to build the modules Quote CC [M] drivers/net/wireless/libertas_uap/uap_main.o CC [M] drivers/net/wireless/libertas_uap/uap_sdio_mmc.o CC [M] drivers/net/wireless/libertas_uap/uap_proc.o drivers/net/wireless/libertas_uap/uap_proc.c: In function 'uap_proc_read': drivers/net/wireless/libertas_uap/uap_proc.c:83:5: error: implicit declaration of function 'netdev_for_each_mc_addr' drivers/net/wireless/libertas_uap/uap_proc.c:83:41: error: expected ';' before '{' token drivers/net/wireless/libertas_uap/uap_proc.c:92:41: error: expected ';' before '{' token make[4]: * [drivers/net/wireless/libertas_uap/uap_proc.o] Error 1 make[3]: * [drivers/net/wireless/libertas_uap] Error 2 make[2]: * [drivers/net/wireless] Error 2 make[1]: * [drivers/net] Error 2 make: *** [drivers] Error 2 When I look at the lines 83 to 92 of the kernel sources file drivers/net/wireless/libertas_uap/uap_proc.c Code: netdev_for_each_mc_addr(ha, netdev) { ++i; } p += sprintf(p, "MCCount=\"%d\"\n", i); /* * Put out the multicast list */ i = 0; netdev_for_each_mc_addr(ha, netdev) { Is it just missing a ; before the { I can blindly make the change but perhaps someone with knowledge of C could give me a pointer?

Thanks for the information. I found this on the web and it seems there is no easy solution to improve wireless signal for the plug http://colinkarpfinger.com/blog/2010/the-dropouts-guide-to-antenna-design/

Chip spec say external antenna is supported http://www.marvell.com/products/wireless/8688.pdf This post confirms that the internal antenna is weak http://www.newit.co.uk/forum/index.php?topic=347.0 Quote The Antenna connector was a query as I guess the wavelength of the 2.4Ghz band is somewhere around 13cm so the internal would be about quarter wavelength at best and I don't suppose it is a folded dipole. With a full wavelength dipole, the ERP from the chipset would probably be sufficient to cover my premises (though whether the heating effect might be a problem in such a confined space). Even if were a runner! what is the part number from Digikey for the cable? Is it 590-1014-ND ADAPTER CABL RPSMA TO U.FL 100MM ? I have a 15 dBi Hawking directional antenna that made a difference for the Linksys wireless bridge over the default omni whip.

I found a mjpeg-streamer binary package for arm here: http://www.friendlyarm.net/forum/topic/279 if you scroll down you will find the version for libjpeg62 http://mjpg-streamer-mini2440.googlecode.com/files/mjpg-streamer-mini2440-bin-libjpeg62.tar.gz I followed the instructions here http://code.google.com/p/mjpg-streamer-mini2440/ This worked for me with a great picture using a Logitech Quickcam Ultravision. I got a kernel freeze when trying the java and javascript pages. This camera isn't fully supported bu the UVC driver so it may not be the plug's fault.

I installed the linux-UVC driver on the plug and I will get libjpeg and libmath from Debian downloads.

39	General Category / Application ideas and development Q/A / Re: Correct "script" for the GCC cross compiler for Sheeva Plug Computer	on: December 08, 2010, 08:19:59 PM
I installed CodeSourcery but am really confused about how to use it and whether it supports the Plug. I am trying to find out the Linker script to use with the Feroceon. According to the pdf that was installed in the docs, the linker scripts support Cortex-M3, ARM Simulator (VFP), ARM Simulator and Cortex-M1. According to this post http://www.codesourcery.com/sgpp/lite/arm/portal/kbentry31 the linker scripts should be obvious but I don't see any in the arm-none-eabi/lib directory When I execute $arm-none-linux-gnueabi-ld --verbose I get this Code: GNU ld (Sourcery G++ Lite 2010.09-51) 2.20.51.20100809 Supported emulations: armelf using internal linker script: ================================================== /* Script for -z combreloc: combine and sort reloc sections / OUTPUT_FORMAT("elf32-littlearm", "elf32-bigarm", "elf32-littlearm") OUTPUT_ARCH(arm) ENTRY(_start) SEARCH_DIR("=/usr/local/lib"); SEARCH_DIR("=/lib"); SEARCH_DIR("=/usr/lib"); SECTIONS { / Read-only sections, merged into text segment: / PROVIDE (__executable_start = SEGMENT_START("text-segment", 0x8000)); . = SEGMENT_START("text-segment", 0x8000); .interp : { (.interp) } .note.gnu.build-id : { (.note.gnu.build-id) } .hash : { (.hash) } .gnu.hash : { (.gnu.hash) } .dynsym : { (.dynsym) } .dynstr : { (.dynstr) } .gnu.version : { (.gnu.version) } .gnu.version_d : { (.gnu.version_d) } .gnu.version_r : { (.gnu.version_r) } .rel.dyn : { (.rel.init) (.rel.text .rel.text.* .rel.gnu.linkonce.t.)

Ooops. The author of the post posted the driver sources on his own site. Got it. Does this mean this is a beta pre-release? Should I wait and see if they roll-out a fully tested and approved version?

41	Hardware and U-Boot firmware / Hardware / Re: external wireless antenna?	on: December 06, 2010, 05:44:12 PM
I think the freezes are due to the wlan client mode. I have had it freeze while downloading deb packages although it has been stable for days at a time. So far I only use it for downloading podcasts with a cron job. I have the same kernel 2.6.32-00007-g56678ec #1 PREEMPT as the author of the other posting. What is the least painful way to cross compile the wireless driver for the plug? http://www.plugcomputer.org/plugwiki/index.php/Compiling_Linux_Kernel_for_the_Plug_Computer My desktop linux box runs a slackware based distro with an older kernel 2.6.22.14 #1 SMP PREEMPT. After the cross compiler, I download the sheeva/plug kernel source for 2.6.32 and build against it? I wouldn't mind testing a binary driver compiled (by someone else) for the default kernel on the plug. Off topic: Why did Globalscale/Marvell provide a third party site for the Libertas driver? It is some web design firm that does very impressive work http://www.inovo.ca/portfolio/index.php Scroll through some of the pages they designed for clients. Hopefully their kernel drivers are as good as their artwork.

I agree it's u.fl but the cable from my dead wet54g doesn't connect with the guruplug pcb connector. Similar appearance but not exactly the same. I'm not sure my soldering iron is fine enough to connect wires to the pcb pads. I have been using my plug as a wep client and I get the occasional hangs reported by others on the forum. The current location is a bedroom above the AP.

I put copper heatsinks on the chips and removed the power supply. I have a 40mm 5V fan attached to the plug pulling air through a 35 mm hole I cut on the opposite side from the ethernet/usb ports. I am using a spare external 3A 5V Netgear powersupply. I moved the pcb wires from the original internal plug power supply to a jack that I attached to the plug. I don't have a gigabit switch but the copper heatsinks are room temp. I still get system freezes due to the fact that it is in client mode.

I have looked at many samba tutorials and how-to s and was frustrated by the inconsistencies. Two mistakes I made were that I forgot to change fstab stetting for the microSD from vfat to ext2 and I was using PyNeighborhood on my desktop linux box. It turns out that PyNeighboorhood was giving a mount error because /mnt/lan didn't exist not because of my smb.conf settings. Needless to say, now my desktop machine shows this Code: darkstar:$ smbclient -L mywifiplug -N Domain=[MYWIFIPLUG] OS=[Unix] Server=[Samba 3.2.5] Sharename Type Comment --------- ---- ------- plug-storage Disk The Wifi-Sheevaplug Storage IPC$ IPC IPC Service (Samba Server Version) Domain=[MYWIFIPLUG] OS=[Unix] Server=[Samba 3.2.5] Server Comment --------- ------- Workgroup Master --------- ------- LOCALDOMAIN MYWIFIPLUG Code: darkstar:$ smbclient //192.168.1.100/plug-storage -N Domain=[MYWIFIPLUG] OS=[Unix] Server=[Samba 3.2.5] smb: \> The problem now is that I can't list the share or see contents because of this error Code: smb: \> ls Call returned zero bytes (EOF) listing \* Error in dskattr: Call returned zero bytes (EOF) Google turned up a french link describing the same problem and a fix http://forums.fedora-fr.org/viewtopic.php?pid=165562 but I am not familiar with the /etc/nsswitch.conf file On the guruplug, mine looks like this Code: # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed, try: # `info libc "Name Service Switch"' for information about this file. passwd: compat group: compat shadow: compat hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis Any ideas on [NOTFOUND=return]?

44	General Category / General Discussion / permissions for samba to share usb drive with windows?	on: November 23, 2010, 05:24:56 PM
I have a microSD card and it was originally VFAT. I was able to browse windows network neighborhood and see files on /media/usb0. I reformatted the microSD so that a user account can download podcasts according to a cron job (didn't want root to do this). Now I am unable to figure out samba settings to allow read access to the drive. My desktop linux box can't access LOCALDOMAIN so it is definitely a plug issue. I don't want to log in to the share just to read files.
