<div dir="ltr">Hi Deval,<div>Your proposal looks good. I would suggest adding a step where you build a known BSP with BSD lib support. It will help you become familiar with the development process. </div><div>You should also address which Raspberry Pi model you will support. Now that there are so many Raspberry Pi models, it might make the project more complicated:</div><div>Original raspberry Pi Model A & A+: a single built in USB port in the BCM2835 CPU. No ethernet or USB hub. </div><div>Raspberry Pi Model B & B+: USB hub and Ethernet in LAN9512 chip. </div><div>Raspberry Pi 2 Model B: USB hub and Ethernet in LAN9514 chip. </div><div>Raspberry Pi 3 Model B: I would not worry about this one yet. </div><div>Raspberry Pi Zero: A single USB OTG port , no ethernet or USB hub. </div><div><br></div><div>I would pick one of them and get it working before seeing if another model could be supported. </div><div><br></div><div>If the Raspberry Pi 1/B+ and 2/B Hubs are functionally the same ( LAN9512 vs. LAN9514 ), this would support the widest range of devices out there. </div><div><br></div><div>If you have time, I would love to see USB support for the BCM2835 on the Pi Model A+ and especially the Pi Zero. </div><div><br></div><div>Thanks,</div><div>Alan</div><div> </div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Mar 22, 2016 at 8:52 AM, Deval Shah <span dir="ltr"><<a href="mailto:deval.maker@gmail.com" target="_blank">deval.maker@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello,<br>

I have updated my draft proposal and shared on the tracking page. I'm<br>
sharing it here as well. <a href="https://goo.gl/QQiAf6" rel="noreferrer" target="_blank">https://goo.gl/QQiAf6</a><br>
<br>
Sorry, I was busy with my Mid-Semester exams, could not update earlier.<br>
<br>
Since this is a draft proposal, it may not be completely polished yet.<br>
I'd appreciate any comments on it, especially regarding the project description<br>
and timeline.<br>
<br>
Thank you.<br>
