It looks good.<br>
<br>
I think adding the commands you use after the text "Unzip the downloaded Zip<br>
file inside this directory." helps. If the blob captures the exact commands it<br>
makes it easier for me to follow. The EPICS link is hard to find.<br></blockquote><div><br></div><div>Thank you so much for the feedback. I will fix that. </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<br>
Target Architecture seems likely. I would assume we need to look into what these<br>

<br>
Please post the commands and the output. I find it hard to follow what is<br>
happening here.<br>
