Ideally yes but we need to investigate whether mainline has enough to get to a console prompt on the panda, I do not have that information at the moment but maybe John does? -- omap kernel does not support omap4 https://bugs.launchpad.net/bugs/623077 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 623077] Re: omap kernel does not support omap4
Mainline 2.6.36 does not have enough to get to a serial console prompt on Panda. For example: mmc support is broken. I've started adding patches to 2.6.36 to see how far I can get, but I am hampered by a Panda with bad POP memory. This results in random segfaults. I should have a replacement Panda in the next day or two.

Re: [Bug 623077] Re: omap kernel does not support omap4
(Sorry for top-posting. Not sure what's the protocol on this list). I've made sure mainline works great on OMAP4. On top of current mainline head, we need the following two patches that are not yet in mainline. [1] https://patchwork.kernel.org/patch/279661/ [2] https://patchwork.kernel.org/patch/294842/ Should be there by v2.6.37-rc2. omap2plus_defconfig should be just fine. This boots up to a console prompt on my pandaboard. For kernel/linux-linaro-2.6.35.git, I'll cherry-pick a minimal set of patches to get omap4 working. - Anand On Tue, Nov 2, 2010 at 9:33 AM, Jamie Bennett j...@canonical.com wrote: Ideally yes but we need to investigate whether mainline has enough to get to a console prompt on the panda, I do not have that information at the moment but maybe John does? -- omap kernel does not support omap4 https://bugs.launchpad.net/bugs/623077 You received this bug notification because you are a direct subscriber of the bug.

Re: [Bug 623077] Re: omap kernel does not support omap4
2.6.37-rc1 is better. These two patches should be all that are needed, as the MMC support is fixed there, as also basic ES2.0 support for the newer boards.

@Loic I think Lee understands this hence the break-down of required patches in his links above. A serial console is definitely what we are after and the 16 patches that Lee highlights in the last link are a good initial investigation point, at least 5 of which are not needed. -- omap kernel does not support omap4 https://bugs.launchpad.net/bugs/623077 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
