As per the Instructions provided on the Website, I plugged in my USB Stick into the USB1 - bottom Port and followed the Instructions, and typed the below instruction and result also shown below.
root@ruggedboard-a5d2x:~# mount /dev/sda1 /etc
mount: mounting /dev/sda1 on /etc failed: No such file or directory
I have a small doubt on this regard to the team who has posted or created the testing procedure, have you throughly tested the Instructions you have posted on the Developer Website. None of the Peripheral Testing Procedures posted on this Website are working right at first time.
Due you want the client to test what you have posted on developer website, come to community website and complaint that the instructions are not working and then you give solutions. Can't the team act proactively, test the instructions posted at your end and correct them accordingly.
I am really sorry to say this, you are wasting the client's time by following your Developer's Website.
