<div dir="ltr">Nice work Qiao!<div><br><div>Andre had submitted the patches for GPIO, SPI, and I2C including recommended fixes. It was then recommended that we switch to the new Linux based I2C API, and we ( or I ) got stuck there.</div><div>For the time I have available, it was not going to be a 1 or 2 day fix to move Andre's I2C implementation to the new Linux based API. It was taking me a while just to understand what needed to be done.</div><div><br></div><div>A little later today, I will try to come up with a proposal to split the Pi work so it can be done by 3 participants.. But we need to decide if re-doing the I2C implementation should be part of the work, or if we should use Andre's initial implementation as a baseline for everyone.</div><div><br></div><div>Also, I will submit basic patches to create a raspberrypi2 BSP variant. I have built both the raspberrypi and raspberrypi2 BSPs and tested ticker so far.</div><div><br></div><div>Alan</div><div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Mar 15, 2015 at 7:11 AM, Gedare Bloom <span dir="ltr"><<a href="mailto:gedare@rtems.org" target="_blank">gedare@rtems.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><div class="gmail_extra"><br><div class="gmail_quote"><span class="">On Sun, Mar 15, 2015 at 5:50 AM, QIAO YANG <span dir="ltr"><<a href="mailto:yangqiao0505@me.com" target="_blank">yangqiao0505@me.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div>Hi !<br><br>I've managed to run a hello demo on RPI B/B+, including a demo for loading an image by u-boot (I don't have an ethernet cable on my hand, but I'm going to be able to load the image by tftp for dev).<br><br>If I've got it right, to prepare my proposal I may choose part of the TODO list , look into the implementation detail and schedule it.

Get #1-3 mergeable. May not take much. Then do #4 SD-card support and
