Any updates to meta-zynq in the pipeline?

Any updates to meta-zynq in the pipeline?

Hi Bruce,
                  I'm about to start with my Xilinx ZC702 development board, and I was wondering if there are any updates planned to the meta-zynq repository?

In an earlier thread, you had mentioned that a whole bunch of updates were pending to the meta-zynq layer:

There are updates planned, but with some vacations (mine and others), since
that last update things slowed down a bit. But work is proceeding,
I expect something in the next few weeks.

In particular, as an initial item, the BSP can be bumped to the Yocto
1.3 (3.4) kernel, and complete some work on remaining issues with the
layer.

After that, SDK updates, and other enhancements would be in the
pipeline, but i don't have a complete visibility into those yet.

Cheers,

Bruce

If you are interested in a kernel built direct from the Xilinx repo look at:

https://github.com/balister/meta-zynq

I just pushed use changes yesterday and could use some help testing them.

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'm more interested in updates to the machine configuration and tune files for the Zynq-7020 processor. Are there any updates planned for these? The processor uses a ARM Cortex A9 dual core CPU, so I was wondering where one draws on from, in order to get an accurate representation of the processor. e.g. use TRM for Zynq-7020 and then look a a TI OMAP 4430 or Freescale i.MX 6 dual core machine configuration, etc?

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.

Best regards,

Elvis Dowson

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.

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 :)

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".

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.

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.

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

Best regards,

Elvis Dowson

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.

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

Bruce
