Using flex-installer to create and format the partitions for SD on a LS1043ARDB reference board

Hello...

I just got LS1043ARDB and tried to follow the steps described in Layerscape SDK user guide

to create and format my SD on reference board.

I inserted my SD card in the slot of front chassis and I was able to find mmcblk0, mmcblk0p1 by a command as described in section

• To deploy custom LSDK images on a reference board running TinyLinux.

cat /proc/partitions

Also mmcblk0, mmcblk0p1 were there when I checked by

ls -al /dev/mmcblk*

Here is the screenshot

root@TinyDistro:~# cat /proc/partitions 31 11 1024 mtdblock11 31 12 9216 mtdblock12 179 0 7830528 mmcblk0 179 1 7829504 mmcblk0p1 root@TinyDistro:~# ls -al /dev/mmcblk* brw-rw---- 1 root disk 179, 0 Feb 22 00:48 /dev/mmcblk0 brw-rw---- 1 root disk 179, 1 Feb 22 00:48 /dev/mmcblk0p1 root@TinyDistro:~#

I ran flex_installer -i pf...blabla.

But to my disappointment, TinyDistro spit out following error messge.

root@TinyDistro:~# flex-installer -i pf -d /dev/mmcblk0 instruction: pf BusyBox v1.23.2 (2017-07-11 15:08:34 CST) multi-call binary. Usage: grep [-HhnlLoqvsriwFE] [-m N] [-A/B/C N] PATTERN/-e PATTERN.../-f FILE [FILE]... Partitioning /dev/ ... Welcome to fdisk (util-linux 2.26.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. fdisk: cannot open /dev/: Is a directory

And I can't see anything in /mnt/ directory where my mmcblk0 is supposed to be placed.

Anyone possibly help me out...

Many thanks in advance...
