I am using Xenomai 2.6.0. We wish to run Xenomai on two different target boards, one uses the Freescale MPC8378 CPU, which is powerpc, the other uses the Freescale MX35 which is arm11. This is for real products that are under development, so there are some factors that affect our choices. For instance, to simplify maintenance of these cards for many years to come, we want to use the same kernel version on the MPC8378 as we do on the MX35. For this reason, we chose to use kernel 3.0.13, because there are Adeos patches against kernel 3.0.13 for both arm and powerpc. However, I know that the Adeos patches and kernel 3.0.13 are not really supported by Xenomai 2.6.0 because they are only in the Git tree and not in the official tarball download. Nonetheless, the powerpc target has been running with no problem for some time now, and the card is actually in product verification now, which means that testing has not discovered any problems with Xenomai 2.6.0 on that target. I am now attempting bring Xenomai up on the mx35 card.
I am using the adeos patch adeos-ipipe-3.0.13-arm-1.18.08.patch. I tried following the README for the MXC, but the Freescale IMX git has no tag rel_imx_3.0.15_12.03.00. The denx tree has the tag, but the mxc patches as described in the README do not apply without errors. Even after fixing the patch rejects, I ended up with compilation errors, so I lost confidence in that approach. So, I applied the adeos-ipipe-3.0.13-arm-1.18.08.patch to the kernel.org 3.0.13 kernel, without the pre and post patches, which went without error. The kernel boots, and many things work, but the FEC Ethernet is broken with an MDIO read timeout. I would like to debug this issue and provide whatever fixes back to the community. I don't really know where to start. I am looking for some guidance on what I should do to debug the issue.
