Configuring RedBoot The Redboot configuration is made using a Minicom session that need to be established between host and target through serial port. To have an operational system been executed just on the power on, configure the right for Boot script. The chooses are shown in #Boot Script section. To avoid the start of operational system, power on the board and press CTRL-C immediately. Wait until RedBoot> prompt appears. Overview The main command for beginners is fconfig -l that can be abbreviated as fc -l This command shows the actual configuration of Redboot, like: RedBoot> fc -l Run script at boot: true Boot script: .. load -r -b 0x100000 /tftpboot/zImage .. exec -b 0x100000 -l 0x200000 -c "noinitrd console=ttymxc0,115200 root=/dev/n" Boot script timeout (1000ms resolution): 1 Use BOOTP for network configuration: false Gateway IP address: 10.29.241.254 Local IP address: 10.29.241.6 Local IP address mask: 255.255.254.0 Default server IP address: 10.29.244.99 Board specifics: 0 Console baud rate: 115200 Set eth0 network hardware address [MAC]: false GDB connection port: 9000 Force console for special debug messages: false Network debug at boot time: false RedBoot> Run script at boot: set true for booting with a script or false to always enter on prompt directly Boot script: define what commands to execute as script at the startup Boot script timeout: how many time to wait before execute boot script Use BOOTP for network configuration: set true for getting configuration from BOOTP or false for manually configuring gateway and IP address Gateway IP address: The IP address of the gateway Local IP address: The board IP address Local IP address mask: The board IP mask address Default server IP address: The host IP address when NFS and TFTP server are running Configuring Network Execute the command to configure network parameters: RedBoot> fc This step guarantee the possibilities to load images from some server previously connected and configured. For Use BOOTP for network configuration: answer false. For Gateway IP address: type the gateway IP address of your network; For Local IP address: type an IP address to your board, it needs to be a valid IP in your network; For Local IP address mask: type the IP mask address; For Default server IP address: type the IP of your host server where are running TFTP and NFS. Pay special attencion for Update RedBoot non-volatile configuration - continue (y/n)?. Answer y to have your configuration saved in the flash. To verify if your configuration is working use ping, be patient this command is very slow: RedBoot> ping -h 10.29.244.99 Network PING - from 10.29.241.6 to 10.29.244.99 PING - received 10 of 10 expected Use the "-n" option to change the number of pings and the "-r" option to speed things up, such as: ping -n 3 -h 10.29.244.99 -r 10. The boot script configuration is done in the next section. Boot Script NFS Boot In NFS Boot mode, a kernel image and a root file system image are loaded from a configured server through TFTP and NFS that can be executed doing the development more easy. To configure RedBoot for NFS Boot reset the board and press CTRL-C immediately. In a Minicom session type fc to modify the configuration boot. Enter the script boot below RedBoot> fc Run script at boot: true Boot script: Enter script, terminate with empty line >> load -r -b 0x100000 /tftpboot/zImage >>> exec -b 0x100000 -l 0x200000 -c "noinitrd console=ttymxc0,115200 root=/dev/nfs nfsroot=10.29.244.99:/tftpboot/rootfs init=/linuxrc ip=10.29.241.6:10.29.244.99" >> Boot script timeout (1000ms resolution): 1 Use BOOTP for network configuration: false Gateway IP address: 10.29.241.254 Local IP address: 10.29.241.6 Local IP address mask: 255.255.254.0 Default server IP address: 10.29.244.99 Board specifics: 0 Console baud rate: 115200 Set eth0 network hardware address [MAC]: false GDB connection port: 9000 Force console for special debug messages: false Network debug at boot time: false Update RedBoot non-volatile configuration - continue (y/n)? y ...

The first line load the kernel image (zImage) by TFTP from /tftpboot, the directory configured in TFTP.\ The second line executes the kernel and mount the root file system using NFS. The path /tftpboot/ltib indicates the path that should be exported in the host machine. (It's the path in the /etc/exports) 10.29.244.99 is the host IP address 10.29.241.6 is the target IP address Flash Boot For flash boot the Boot Script differs a little bit: fis init kernel exec -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock8 rw rootfstype=jffs2 ip=none" The value for root can be different for each board type.

current imx6 bsp, not only ltib but also yocto couldn't support subtitle. now we have two solution to support subtitle on yocto, 1)one is extract the subtitle, then draw the subtitle on the video by UI, which is supported by the imxplayer. this solution is using QT by imxplayer, so if you build yocto, should choose QT as target. basicly, aiurdemux send the text to the QT by appsink, then QT draw the text on the UI layer. when build the yocot, pls using the command as below: " bitbake fsl-image-qt5" copy the font libary to the /usr/lib/fonts, then when you play the imxplayer, choose the font you need. 2)another one is blending the subtitle on the video buffer by gstreamer, then output with video enable gst pango lib in gstreamer1.0-plugins-base change playbin flag to disable native video flag basetextoverlay apply patch http://cgit.freedesktop.org/gstreamer/gst-plugins-base/commit/ext/pango/gstbasetextoverlay.c?id=267a8c24af4f02ba6f3075bd589d3c5d1dc826e9 use following command line gst-launch-1.0 playbin flags=0x17 uri=file://$VIDEO_FILE suburi=file://$SUBTITLE_FILE

You can create GTK applications manually—this is just like creating Graphics Java Applications. It uses a similar layout idea! Copy this example and save as helloworld.c: /* example-start helloworld helloworld.c */ #include <gtk/gtk.h> /* This is a callback function. The data arguments are ignored * in this example. More on callbacks below. */ void hello( GtkWidget *widget, gpointer   data ) {    g_print ("Hello World\n"); } gint delete_event( GtkWidget *widget, GdkEvent  *event,  gpointer   data ) {    /* If you return FALSE in the "delete_event" signal handler,     * GTK will emit the "destroy" signal. Returning TRUE means     * you don't want the window to be destroyed.     * This is useful for popping up 'are you sure you want to quit?'     * type dialogs. */    g_print ("delete event occurred\n");    /* Change TRUE to FALSE and the main window will be destroyed with     * a "delete_event". */    return(TRUE); } /* Another callback */ void destroy( GtkWidget *widget, gpointer   data ) {    gtk_main_quit(); } int main( int   argc, char *argv[] ) {    /* GtkWidget is the storage type for widgets */    GtkWidget *window;    GtkWidget *button;       /* This is called in all GTK applications. Arguments are parsed     * from the command line and are returned to the application. */    gtk_init(&argc, &argv);       /* create a new window */    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);       /* When the window is given the "delete_event" signal (this is given     * by the window manager, usually by the "close" option, or on the     * titlebar), we ask it to call the delete_event () function     * as defined above. The data passed to the callback     * function is NULL and is ignored in the callback function. */    gtk_signal_connect (GTK_OBJECT (window), "delete_event",                        GTK_SIGNAL_FUNC (delete_event), NULL);       /* Here we connect the "destroy" event to a signal handler.      * This event occurs when we call gtk_widget_destroy() on the window,     * or if we return FALSE in the "delete_event" callback. */    gtk_signal_connect (GTK_OBJECT (window), "destroy",                        GTK_SIGNAL_FUNC (destroy), NULL);       /* Sets the border width of the window. */    gtk_container_set_border_width (GTK_CONTAINER (window), 10);       /* Creates a new button with the label "Hello World". */    button = gtk_button_new_with_label ("Hello World");       /* When the button receives the "clicked" signal, it will call the     * function hello() passing it NULL as its argument.  The hello()     * function is defined above. */    gtk_signal_connect (GTK_OBJECT (button), "clicked",                        GTK_SIGNAL_FUNC (hello), NULL);       /* This will cause the window to be destroyed by calling     * gtk_widget_destroy(window) when "clicked".  Again, the destroy     * signal could come from here, or the window manager. */    gtk_signal_connect_object (GTK_OBJECT (button), "clicked",                               GTK_SIGNAL_FUNC (gtk_widget_destroy),                               GTK_OBJECT (window));       /* This packs the button into the window (a gtk container). */    gtk_container_add (GTK_CONTAINER (window), button);       /* The final step is to display this newly created widget. */    gtk_widget_show (button);       /* and the window */    gtk_widget_show (window);       /* All GTK applications must have a gtk_main(). Control ends here     * and waits for an event to occur (like a key press or     * mouse event). */    gtk_main ();       return(0); } /* example-end */

It is one mandatory patch if you are in the case: The chip you are using is imx6sx TO1.3 and newer, and use the kobs-ng to flash your image to the Nand memory chip. If you are using MFG, you also need rebuild the kobs-ng, and update the binary into your MFG tool.  The patch have been integrated into the default release yocto_4.1.15, but if you are using the older version release before yocto_4.1.15, please make sure you have integrated the modification when you need to use kobs-ng to flash the image to Nand memory chip. commit 5ecf08703da489a3bd317341f630870a3d07dab9 Author: Han Xu <[email protected]> Date:   Thu Jan 28 14:40:14 2016 -0600     MMT-105: change the i.mx6sx revision check change the i.mx6sx revision check since v1.3 uses v1.2 boot config as well.     Signed-off-by: Han Xu <[email protected]>     (cherry picked from commit 1dac0c14d1e2016c2fa804f6628543d8d238c680) diff --git a/src/plat_boot_config.c b/src/plat_boot_config.c index 461675a..e1ef6f3 100644 --- a/src/plat_boot_config.c +++ b/src/plat_boot_config.c @@ -1,5 +1,5 @@ /* -* Copyright (C) 2010-2015 Freescale Semiconductor, Inc.
