Linux/AM3351: Kernel boot hangs

Please post details. What is the boot device? What is the board configuration? Also post the boot log file.

hi i am using mmc boot for custom board, there is no EEprom in my case,

i am using ti-processor-sdk -am335x-03.00.00.04 sdk

Thankyou,

I checked it look same as my env settings.

hi, eeprom is not there in my custom board,
please suggest me what are the things we need to take care for sd card & Nand boot

The NAND timings are vendor specific and depends on the NAND chips which you are using. They are describe in the u-boot/arch/arm/cpu/armv7/omap-common/mem-common.c file. You can find an example of patch changing NAND timings at:
lists.denx.de/.../215582.html
But I suggest you to start with linked below guides about MMC and NAND booting:
processors.wiki.ti.com/.../AM335x_PSP_User's_Guide
processors.wiki.ti.com/.../AM335x_U-Boot_User's_Guide
