Hello,

I think problem is in below line, u didn't specify

bootcmd_mmc=run bootargs_base bootargs_mmc;mmc dev 1;mmc read ${loadaddr} 0x800 0x2000;bootm

try to do below and post ur result.....

bootcmd_mmc=run bootargs_base bootargs_mmc;mmc dev 1:1; load mmc 1:1 10800000 uImage;bootm

and if above not work then try these 2 belows....

bootcmd_mmc=run bootargs_base bootargs_mmc;mmc dev 1:1;mmc read ${loadaddr} 0x800 0x2000;bootm

bootcmd_mmc=run bootargs_base bootargs_mmc;mmc dev 0:1;mmc read ${loadaddr} 0x800 0x2000;bootm

and make sure about this that your uImage/RFS is in 5th partition of SD card as ur argument showed like this -> root=/dev/mmcblk0p5,so verify it 1st.

post ur results and output.

Hope this will help you

Regards

seems you selected the Android profile in MFGtool. please select the Linux Profile in MFGtool to write the linux images on your board.

You may use zImage to have a try.

All the best
