Hi,
I just took a quick look both the repos

My initial reaction is that I think Philip's repo appears to better structured, 
and attempts to use the xilinx kernel and u-boot repos, which for these targets 
is a good thing, given the state of the development for this new board.


Xilinx sponsored the one that I've "watching over" for the moment,
and they do plan to address the issues.

I said in some older threads, but I can say it again here. It's Xilinx's
board, so their voice carries the most weight, we just need to be patient
and give them time to come up to speed.



I also think its probably good to take then best of both repos, and maintain a 
single meta-zynq layer, since both these repos are in its initial stages.


That's already the plan :) But I'm waiting on things that don't work on
a schedule that I control.

Cheers,

Bruce



I'll give more feedback, as I progress with my build and test runs on the 
target board.

It is setup to boot from a SD card. You have to take the output of the u-boot 
recipe and use the Xilinx tools to combine it with the fsbl to get the required 
BOOT.BIN file.


I'll help out and test your layer first, and let you know. It's going to take 
me a while to get used to this new board. I always find that I end up spending 
more than 2 to 3 months, just getting to know each platform to a good level, 
the last two ones being the Gumstix TI OMAP 3530 and the Xilinx ML507. I'm 
going to brace myself, its going to be a deep dive I think! :-)

Adrian Alonso's meta-xilinx layer had some *.bbclass files, that invoked the 
Xilinx tools to create the ace image files, so perhaps that could be modified 
to automate the process or getting the final BOOT.BIN file.


Unfortunately I do not have the Xilinx tools installed on the machine I 
do the builds on. I'd love to post a working BOOT.BIN, but 1) I haven't 
tested this on he zc702 yet, and 2) I need to work out if I can 
distribute the binary since it includes GPL u-boot and non-GPL fsbl.


I understand it will take some time to get up to speed. I am finding the 
Xilinx workflow based around planAhead to be "challenging".


Philip

AFAIK, yes. Xilinx themselves are gearing up to take over this
work, but I can't speak for them, and haven't heard anything since
before I went on vacation. I'm hoping that this will pick up again
soon.



The kernel and u-boot recipes, I can migrate to the latest 3.5 and 2012.x 
versions, so that shouldn't be a problem for me.


ok! At some point the layer will become (hopefully) yocto BSP
compliant, and at that point we'll get some consistency in kernel
version where it will be on one of the yocto versions, LTSI, etc,
since spraying all over the map on versions doesn't help everyone :)
