HDMI resolutions are not detected on Pandaboard A4 (Omap 4430 ES2.3 silicon)

Code for detecting OMAP4430 ES2.3 (embedded into Pandaboard A4) is missing. Attached patch adds this.

This patch was tested on top of 1206.15 oneiric kernel and proved to fix the issue.

I hate to be a total noob, but can someone point me in the direction of how to apply this patch? I followed the instructions for installing the pre-built ubuntu 10.10 from the omapedia website. I have tried to use the ubuntu patch command in the linux-headers directory, but it keeps saying failed. I guess I'm doing something wrong.

Thanks.

You need to get the kernel sources and apply the patch to it. So either apt-get source on the kernel package, or clone the kernel git tree.

Also this patch applies on Oneiric (11.10), not 10.10.

Here is the path to the Oneiric tree (look into ti-omap4 branch): http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-oneiric.git;a=summary

Here is an updated patch. Previous one was breaking omap4430 ES2.2 detection and was claiming ES2.3 instead.

The attachment "0001-omap4-add-4430-ES2.3-support.patch" of this bug report has been identified as being a patch. The ubuntu-reviewers team has been subscribed to the bug report so that they can review the patch. In the event that this is in fact not a patch you can resolve this situation by removing the tag 'patch' from the bug report and editing the attachment so that it is not flagged as a patch. Additionally, if you are member of the ubuntu-reviewers team please also unsubscribe the team from this bug report.

This bug is awaiting verification that the kernel for Oneiric in -proposed solves the problem (3.0.0-1207.16). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-oneiric' to 'verification-done-oneiric'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

As stated in #1, the original patch was tested on top of 1206.15 oneiric kernel and proved to fix the issue.

I do not have access to a Panda A4, so cannot confirm the final fix also works on top of 1207.16.

@Charles Breingan: may be you can confirm/want to test everything is ok? Instead of building the kernel by hand, just install the 3.0.0-1207.16 from -proposed (if you want to install the linux-image deb directly you can grab it from http://ports.ubuntu.com/pool/main/l/linux-ti-omap4/linux-image-3.0.0-1207-omap4_3.0.0-1207.16_armel.deb)

For your information, I tried the kernel from -proposed on my A4, and it works well. I haven't tried any older board to see if it's still working there.

Ok thanks for testing, marking as verification-done then.

This bug was fixed in the package linux-ti-omap4 - 3.0.0-1207.16
