[U-Boot] How to resolve CRC issue in Uboot and maintain the env variables

[Zaheer Sheriff]

Stefan,

I thought the error is generic, I never know it is processor or board 
specific error.
Here are the details:
OMAPL138 EVM board 
u-boot version 2011.9 NOvember release.

modified env in da850 config file as :
-------
/*
 * Linux Information
 */
#define LINUX_BOOT_PARAM_ADDR	(PHYS_SDRAM_1 + 0x100)
#define CONFIG_CMDLINE_TAG
#define CONFIG_SETUP_MEMORY_TAGS
#define CONFIG_BOOTARGS		"mem=32M console=ttyS2,115200n8 noinitrd rw 
ip=10.1.5.115:10.1.5.69:10.1.5.1:255.255.255.0::eth0: root=/dev/nfs 
nfsroot=10.1.5.69:/home/targetNFS"
#define CONFIG_BOOTCOMMAND	"if mmc rescan 0:1; then fatload mmc 0:1 
0xc0700000 uImage; bootm c0700000; fi;"
#define CONFIG_BOOTDELAY	3
#define CONFIG_EXTRA_ENV_SETTINGS "ethaddr=00:08:ee:03:6a:c4\0"
---------------------------
Will this extra env creates CRC error.

this is my env variable:
 
setenv bootcmd 'sf probe 0;sf read c0008000 40000 340000; go c0008000'

Image file size is: 335268 hex
 
how to resolve this.
