Programming Tool Problem - Will not boot Ramdisk

[PaulDeMetrotion]

I am having difficulty programming an on-board SPI-NOR device on a custom i.MX6Q board.

I have built all of the appropriate manufacturing files and placed them in the proper directory. I am using the MfgTool2 program. Everything appears to be working properly but when the kernel gets to the end of execution, it attempts to mount a file system rather than executing the Ramdrive currently in memory. This failure causes none of the Updater commands to be executed.

Any suggestions will be greatly appreciated!

Here are the important parts of the console output:

Is it posible to boot the system from different source?, we need to make sure we have access to the spi-nor from linux.

[PaulDeMetrotion]

Yes, I can boot from an SD device, a micro-SD device, and a SATA/CFAST device. Wouldn't the following indicate that the SPI-NOR is being seen:

Please append a correct "root=" boot option; here are the available partitions:

1f01               8 mtdblock1  (driver?)

[AlejandroSierra]

Could you please include all the log message from the begining?.

Our Sabreauto board has pin conflicts on the SPI-NOR and WEIM-NOR, therefore we set a kernel parameter  called "SPI-NOR" to enable it. Is it posible to boot the system from different source?, we need to make sure we have access to the spi-nor from linux.

How are you building your mfg tool kernel image?

[PaulDeMetrotion]

Using LTIB, I select the 'Build mfg firmware' option and start the build. I have created the manufacturing specific include file which follows the instructions found in the Linux or Android Firmware Development Guide. Everything appears to be good.

[karina_valencia]

AlejandroSierra will  work on this case.

[PaulDeMetrotion]

I have more information to share. I have tracked the problem to the function kernel_init which is below. Within this function there is a call to sys_access that returns a -2 which indicates an error has occurred. Because of the error the ramdisk_execute_command variable is nulled and the kernel searches for an existing file system. I do not know why the sys_access function fails – could this indicate a memory error?

If I use the emulator I can trap after this function and force the return variable to be a zero and restart the boot process. If I do this I get the following console output: Failed to execute /linuxrc. This is the right function to execute according to the environment variables.

Could this possibly be a configuration setting?

static int __init kernel_init(void * unused)

{

        /*

         * Wait until kthreadd is all set-up.

         */

        wait_for_completion(&kthreadd_done);

        /* Now the scheduler is fully set up and can do blocking allocations */

        gfp_allowed_mask = __GFP_BITS_MASK;

        /*

         * init can allocate pages on any node

         */

        set_mems_allowed(node_states[N_HIGH_MEMORY]);

        /*

         * init can run on any cpu.

         */

        set_cpus_allowed_ptr(current, cpu_all_mask);

        cad_pid = task_pid(current);

        smp_prepare_cpus(setup_max_cpus);

        do_pre_smp_initcalls();

        lockup_detector_init();

        smp_init();

        sched_init_smp();

        do_basic_setup();

        /* Open the /dev/console on the rootfs, this should never fail */

        if (sys_open((const char __user *) "/dev/console", O_RDWR, 0) < 0)

                printk(KERN_WARNING "Warning: unable to open an initial console.\n");

        (void) sys_dup(0);

        (void) sys_dup(0);

        /*

         * check if there is an early userspace init.  If yes, let it do all

         * the work

         */

        if (!ramdisk_execute_command)

                ramdisk_execute_command = "/init";

        if (sys_access((const char __user *) ramdisk_execute_command, 0) != 0) {

                ramdisk_execute_command = NULL;

                prepare_namespace();

        }

        /*

         * Ok, we have completed the initial bootup, and

         * we're essentially up and running. Get rid of the

         * initmem segments and start the user-mode stuff..

         */

        init_post();

        return 0;

}

[PaulDeMetrotion]

Major breakthrough! I copied the initramfs.cpio.gz.uboot file from the Freescale folder titled Mfgtools-Rel-4.0.0_130424_MX6Q_UPDATER. Now the process does not fail where it did previously. It attempts to program the SPI-NOR device but fails. Have not investigated this failure any further.

Question now is should I be creating my own version of the initramfs.cpio.gz.uboot file or just use the Freescale version?

Here is the end of the new console output:
