Hi Ryan!
We are now facing a new challenge! We need to output video from the HDMI1/2 available in the Juno r1 Board.
By checking the device tree, I concluded that video is not supported for now… Can you advise me about this subject?
Thanks,
Joao

Hi Joao,
I see from emails via another route that you've solved your problems by using updated software from Connected Community.
For reference, the Linaro release that supports PCIe on Juno R1 is the "latest.xml" and "juno-oe" variant from this release:

Ryan.

Hi!
My name is Joao Pinto and I am currently developing a pilot project with ARM'
Juno r1 board.
The application is very simple: I have a Synopsys board connected to Juno
through PCIe.
Using ARM' factory kernel image or our own linaro kernel image (using latest
release: 4.1 rc4), PCI initialization log provides some worrying messages
(please check bellow log).

In our initial test, despite the previous failure messages we were able to see

I tried also to read a register from our USB Controller (0xc120) though devmem
(provided by Busybox) using the base address 0x50000000 + 0xc120 offset and the
result is a segmentation fault which is not normal.
In our opinion the PCI has problems in the initialization and obviously that
reflects in its memory mapping.
I would like to know if this is a known issue and what should we do to overcome it.
Thanks,
Joao Pinto
