I resolved that issue by using Cutecom instead of Minicom.

But nowi have to partition the eMMC before i write anything to it . So following the instructions found here

http://processors.wiki.ti.com/index.php/Linux_Core_U-Boot_User's_Guide#Partitioning_eMMC_from_U-Boot

$ uuidgen ...first uuid... $ uuidgen ...second uuid... 
U-Boot # printenv partitions uuid_disk=${uuid_gpt_disk};name=rootfs,start=2MiB,size=-,uuid=${uuid_gpt_rootfs} U-Boot # setenv uuid_gpt_disk ...first uuid... U-Boot # setenv uuid_gpt_rootfs ...second uuid... U-Boot # gpt write mmc 1 ${partitions}

i get an error immediately saying:

data abort.

MAYBE you should read doc/README.arm-unaligned-accessess
pc : [] lr : []
etc..
etc..
etc..

Flags: NzCv IRQs off FIQs on MODE SVC_32
Resetting CPU...

reseting...
ccccccccccc


I cannot find understand this error. What is causing it ? is there any other way to go about partitioning and flashing the MLO, uboot and kernel to eMMC?
