Now, I have some questions:<br>

1. Does anyone have any recommendation on the proposal?<br>

<div><br>
</div>
<div>I like the proposal, but there are a couple of things
that may change slightly:</div>
<div>1. You may want to look into making the UART driver
work in interrupt driven mode, as it is currently polled.</div>
</div>

I will have a look at it.<div class=""><br>

<div>2. For the Framebuffer support, I have been talking to
someone off list that is making progress on implementing a
framebuffer driver. We may want to collaborate with this
person for the framebuffer. </div>

Certainly. I was scheduling the framebuffer work for July, should
that be re-scheduled? <br></div></blockquote><div><br></div><div>July may still work. This gives us time to see what gets accomplished and the work can be integrating it into the RTEMS tree and testing. </div><div><br>

2. Is there any interesting documentation or code you
think I should be looking at right now? For the past month
I have been studying the RPi BSP code and the RPi
architecture for the emmc driver that I am doing for my
final project at the university.<br>

<div>From what I can see, you are off to a very good start!</div>

There is no wiki page for the Raspberry Pi BSP (at least I
have not found any yet). May I create one using the Open
Project template and link it in the Open Projects page
under the BSP section?<br>

<div>I did not create one, so please do.</div>

4. I will create a dedicated development blog for the
project very soon. How frequently should it be updated
until may 19?<br>
<br>
5. How should the communication happen? Also I am not sure
if the Amar Takhar and Muhammad Adnan e-mails are the
correct ones.<br>
<br>
I will also be setting a github repository for this, and I
am also looking to get my own RPi and some peripherals (I
have one at the university right now).<br>

<div><br>
</div>
<div>I have been setting up my Pi for RTEMS development
again. I recently built u-boot and I am going to try to
get it to boot RTEMS images from a TFTP server. This may
help speed up development. </div>
<div><br>
</div>
<div>I am also trying out a FT2232H MiniMod evaluation board
that is supposed to work with the Raspberry Pi JTAG
interface and the OpenOCD project. It also serves as the
USB uart connector. I have it all wired up and I hope to
try getting it to talk to OpenOCD soon. If I get it
working, I will document everything. The FT2232H Minimod
board was $20 USD. </div>

<br></div>
Nice. Looking forward to that, as I still need to look at the
debugging part of the development.<br></div></blockquote><div><br></div><div>The FT2232H MiniMod is working so far! I am able to use the UART and at the same time load and run images over the JTAG interface using OpenOCD. Next, I plan on trying GDB. I will try to document the setup soon, but it just requires ~10 jumper wires to connect the MiniMod to the Pi GPIO header. </div>
<div><br></div><div>I need to use it, because I discovered that the RKI image no longer runs on the Pi. The samples such as ticker still work, so I'm sure it is a problem with the RKI code itself. </div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
