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?

Pt

Please check if i.MX28 LRADC1 pin is pulled up.

Please take a look at the next thread :

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
