Hi,

I would boot from SD card for Linux, but it would boot from TFTP now.

How can I modified it and boot from SD card?

I used the AM1808 development kit and attached SD card to boot.

The follow is the log message when booting from SD.

Booting with TI UBL

Check that you really have a working tftp server running on the address mentioned above and that it has a file named uImage available for download.

Carl,

To boot from the SD card you need to modify your boocmd parameters, probably currently now it set to boot from tftp,

u-boot > setenv bootcmd 'if mmc rescan 0:1; then fatload mmc 0:1 0xc0700000 uImage;
bootm c0700000; fi;'
u-boot > setenv bootargs ‘mem=32M console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw
rootwait ip=off’
u-boot > saveenv

Have a look at this link http://processors.wiki.ti.com/index.php/OMAP-L138_Preparing_SD_Card_for_Boot

which explains you to setup to boot from SD card.
