    I\\\'m very confused. I have readed that at this point the system loads the X to do the configuration and that should not show anything more throw the serial console...should I get any result in my screen? how can I get a bash in the serial console? I have included the init=/bin/bash in the igep.ini file but no effect.. greetings, Adrián

    Hi, Ubuntu by default not open any console in the serial debug console. you\\\'ve any options: a) replace the ubuntu kernel for our kernel. b) mount the rootfs in your pc and enable the console. What kind of monitor are you using? Manel

    Hi, how I haven\\\'t a hdmi monitor, I\\\'m connecting the IGEP to my HDMI TV, but don\\\'t detect any signal. What changes must I do in the rootsf or what kernel can I use for enable a console in the serial connection? Thanks, Adrián.

    what kernel can I use for enable a console in the serial connection?
    [url=http://labs.igep.es/index.php/Linux_Kernel_2.6.35.y_Overview]http://labs.igep.es/index.php/Linux_Ker ... y_Overview[/url] Anyway, don\\\'t use ubuntu use linaro instead, it opens a serial console ... Manel

    Hi, ok! the problem is that I need use Ubuntu by requirements of the library that I want install later. The next step that I want achieve is install the kernel version linux-image-2.6.35-23-omap_2.6.35-23.40_armel.deb to get the wireless working, but I need a terminal or use te GUI (I prefer to work using the GUI) Is true that at this point I must see the X loaded throw the HDMI output? In this case, why I don\\\'t see anything? Otherwise, if the X not loaded, which files should I modify in the rootfs to get a console in the serial connection? A lot of thanks, ;) Adrián.

    That is not a problem due linaro = ubuntu (extacly the same)
    Is true that at this point I must see the X loaded throw the HDMI output?
    Yes if it\\\'s configured correctly for your monitor or TV, this is related to ubuntu kernel and we cannot provide any support related to this kernel as I suggested before replace the ubuntu kernel for our kernel (this is a MUST if you wish support).
    Otherwise, if the X not loaded, which files should I modify in the rootfs to get a console in the serial connection?
    /etc/inittab You should use the ubuntu documentation about how to setup ubuntu, google maybe can help you. [url=https://help.ubuntu.com/community/SerialConsoleHowto]https://help.ubuntu.com/community/SerialConsoleHowto[/url] Manel

    Hi, I have finally decided use linaro and the kernel linux-2.6.35.y. I followed the steps of the this tutorial: [url=http://labs.igep.es/index.php/How_to_boot_from_MicroSD_Card]http://labs.igep.es/index.php/How_to_bo ... croSD_Card[/url] My first problem is that when I type this sentence: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- igep0020_defconfig the console returns: Can\\\'t find default configuration \\\"arch/arm/configs/igep0020_defconfig\\\"! then, I had to change igep0020_defconfig by igep00x0_defconfig.. is this rigth? Now, my board loads and I can see the prompt. If I type \\\"ifconfig\\\" only can see loopback interface. Otherwise, if I type \\\"ifconfig -a\\\" I get the lo and usb0 Link ncap:Ethernet. Is this the eth0 interface? when I type the ifconfig usb0 up command it appears at ifconfig command. My second problem is that I can not activate the wireless interface. I copied sd8686_helper.bin sd8686.bin at /lib/modules directory. Then, I type modprobe_sdio and lsmod and this is my output: libertas_sdio 12712 0 libertas 151437 1 libertas_sdio cfg80211 124656 1 libertas lib80211 3224 1 libertas however, when insert ifconfig wlan0 up I get the next error: wlan0: ERROR while getting interface flags: No such device with dmesg command the output is:

    Hi Adrian, Maybe your wlan interface is not configured properly. What do you have with the following commands? dmesg | grep wlan cat /etc/network/interfaces And also, which kernel are you using exactly (as you said you cannot compile ISEE kernel? Regards, Guillaume

    Adrian, You said: \\\"My second problem is that I can not activate the wireless interface. I copied sd8686_helper.bin sd8686.bin at /lib/modules directory\\\" you have to copy them to /lib/firmware Regards, Guillaume

    Hi, sorry I was wrong, the path when I have copied the files is /lib/firmware. I have installed the kernel version 2.6.35.y, that is the ISEE kernel. Now, when I type \\\"dmesg | grep wlan\\\" I have no output. The output of the \\\"cat /etc/network/interfaces\\\" is: auto lo iface lo inet loopback I have an interface called usb0, but is the USB OMG interface. The kernel does not detect eth0 and eth1 interfaces.. Thanks, Adrián. PD: I have not time now, later I will reply your email! ;)

    Adrian, Take a look at: [url=http://labs.igep.es/index.php/How_to_setup_Marvell_88w8686_SDIO_wifi]http://labs.igep.es/index.php/How_to_se ... _SDIO_wifi[/url] It describes how to setup wlan. Your interface file is not configured for wifi. Also, the output of dmesg | grep wlan is not good. Was the wifi module loaded (see lsmod) when you tried that? Regards, Guillaume

    Hi, I\\\'m trying to follow the tutorial to setup the wifi interface, but have the next problem. I have downloaded the zip file, extracted and copied the bin_sd8686 to my card. Then, I want compile the module, but I can\\\'t because the \\\'make\\\' command and the compiler is not installed. What can I do? See your email, I\\\'m answering you! A lot of thanks, Adrián.

    Adrian, I am not sure of which tutorial you are following. Make command is not available on the board, you have to cross compile the module. Have you recompiled a kernel by your self? By the way, are you using the ISEE virtual machine? Guillaume.
