Linux/TMDSCSK388: Problems with creating SD card for DM388 camera kit

Tool/software: Linux

Hello,

I have modified some configuration options and have compiled using 'make syscal all'. I am trying to write to the SD card as per the steps explained in http://processors.wiki.ti.com/index.php/IPNC_RDK_DM38x_,_DM8127#Boot_setup_for_custom_build.

Here is the script file as provided in the IPNC rdk software. ( I have not modified this script)

In the script in Line 9:

for i in `ls -1 $DRIVE?`; do

 Is the  '?' required. I tried removing the '?' and I still have the same issue.

For some reason sdb1 and sdb2 are not created. However 'lsblk' shows '/dev/sdb'

Does anyone have a hand on this issue?
