IMX28 custom board - command line issue?

Hi

Processor : IMX281

Linux Kernel version:2.6.35

Linux BSP:L2.6.35_1.1.0_130130_source

VDD 5V Only


I have successfully booted from sd card.

But I am facing some issues.

    1. When I turn off and on power, the command line changes.

      i.e., sometimes command line is

         console=ttyAM0,115200 root=/dev/ram0 rdinit=/sbin/init fec_mac=00:08:02:6B:A3:1A gpmi (command line 4)

          or

          console=ttyAM0,115200 ubi.mtd=1 root=ubi0:rootfs0 rootfstype=ubifs rw gpmi (command line 2)

          or

          noinitrd console=ttyAM0,115200 root=/dev/mmcblk0p3 rootwait rw ip=none ssp1(command line 1)

          Actually I have built the image to boot from mmc.

       

          *My custom board doesn't have keys to select different command line options.

    2. When I reboot the system, it shows the error code 0x8020a014 2times.


          0x8020a014 (#define ERROR_DDI_SD_MMC_DEVICE_NOT_SUPPORTED (ERROR_DDI_GROUP |           ERROR_DDI_SD_DRIVER_GROUP | 0x14))

          Then It restarts.

               root@freescale ~$ reboot

               root@freescale ~$ Stopping inetd:

                  Unmounting filesystems

                    Restarting system.

                    0x8020a014

                    0x8020a014

                    0x80502008

          HTLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLFLC

               PowerPrep start initialize power...

    3. reboots on poweroff command ?

what is the reason behind these issues?

Regards

Pt

Hi

     LRADC1 pin is not pulled up.

     when boot from command lines other than mmc, the mmc init is failing

    

     mxs-mmc: MXS SSP Controller MMC Interface driver

     mxs-mmc mxs-mmc.0: MMC HW configuration failed

     mxs-mmc: probe of mxs-mmc.0 failed with error -16
