I just received by very own beaglebone, and I would like to add PTP
hardware clock support for the CPTS unit, but I naturally want to do
this with the latest mainstream kernel and not the hacked up arago 3.2
kernel that ships with the board.
Does any vanilla kernel even boot on this board?
If so, which ones, and how?
I have tried a few variations of kernel/u-boot without any luck.
The u-boot that came with the board is
U-Boot 2011.09-00000-gf63b270-dirty (Apr 24 2012 - 09:51:01)
arm-angstrom-linux-gnueabi-gcc (GCC) 4.5.4 20120305 (prerelease)
GNU ld (GNU Binutils) 2.20.1.20100303
and I also tried the latest version:
U-Boot 2012.10-rc1-00148-g4668a08 (Sep 30 2012 - 09:35:20)
arm-none-linux-gnueabi-gcc (Sourcery G++ Lite 2009q1-203) 4.3.3
GNU ld (Sourcery G++ Lite 2009q1-203) 2.19.51.20090205
Thanks,
Richard

You say that you use CONFIG_ARM_APPENDED_DTB, which means: CONFIG_ARM_APPENDED_DTB: With this option, the boot code will look for a device tree binary (DTB) appended to zImage (e.g. cat zImage <filename>.dtb > zImage_w_dtb). This is meant as a backward compatibility convenience for those systems with a bootloader that can't be upgraded to accommodate the documented boot protocol using a device tree. But in the example you gave, you seem to load the dtb in the "normal" way, with a dtb-aware u-boot. So how do you boot this? With the APPENDED hack? Or just using a recent u-boot?

As I have my own old patch which enabled these two option in omap2plus_defconfig, which I just carry-forward everytime. I just tried with plain vanilla omap2plus_defconfig and it works for me.

There is a DT binding document Documentation/devicetree/bindings/net/cpsw.txt but cpsw does not appear in either am335x-bone.dts, am335x-evm.dts, or am33xx.dtsi, or for that matter, in *any* dts file anywhere. I have looked in mainline master, linux-next, and in the master branch of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap.git Is there an issue keeping the cpsw/DT combination from working? If not, is there a file dts for the bealgebone somewhere? Thanks, Richard ^ permalink raw reply [flat|nested] 20+ messages in thread

Richard I have a working branch for CPSW which is based on 3.5.0-rc6 in the following git repo Repo: https://github.com/hvaibhav/am335x-linux.git Branch: am335x-linux-next-master-cpsw Regards Mugunthan V N ^ permalink raw reply [flat|nested] 20+ messages in thread

I did see the stuff you added into arago for the DM814x, but it didn't look correct to me. Anyhow, I went ahead and wrote my own from stratch, based on the AM335XPSP_04.06.00.08 branch, and it is working well. So go ahead and post your driver, and I'll post mine, and we can go from there. Right now, I can't for the life of me get a mainline kernel to boot on the beaglebone, so I think we should focus on getting the mainline support on the am335x stable before adding new drivers.
