Hello ,
i searched a lot in Google they are suggesting lots of things i try all , but noting is working for me please help.
i am using beaglebone black , and i am trying to build 3.8 kernel for my board . I got successfully zImage but while i am loading it through 4 GB SD card and partition is -----
# sudo fdisk /dev/sdb
Command (m for help): p
Disk /dev/sdb: 1980 MB, 1980760064 bytes
61 heads, 62 sectors/track, 1022 cylinders, total 3868672 sectors

/dev/sdb2 198656 3481599 1641472 83 Linux
I feel that here is some issue with zImage only
Please tell what i should do and where i made mistake on building zImage .
this is my whole log
