problem booting image on target from eMMC4.4

swl — Sat, 10 Aug 2013 14:14:16 GMT

I'm trying to download and boot Ubuntu image from eMMC4.4 via HannStar LVDS.

I follow the "i.MX_6Dual6Quad_Sabre-SD_Linux_User_Guide.pdf" from L3.0.35_4.0.0_docs using the MFGTool to download image into the sabre board.

The cfg.ini file :

[LIST]

name = ubuntu-SabreSD-eMMC

set boot mode as SD3 boot to enter serial download mode for MFGTool

did the following command in U-boot prompt

setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk0p1 rootwait rw video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666'

setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc dev 3;mmc read ${loadaddr} 0x800 0x2000;bootm'

setenv bootcmd 'run bootcmd_mmc'

saveenv

but it hang at the point when I tried to run bootcmd highlighted in red below and subsequently I'm not able to enter U-boot prompt to edit anymore, the only response I get is those that I highlighted in green below.

Is there anybody with similar issue or have some idea where should I go about debugging it?
