Phil, do you have a suitable test kernel and rootfs image available to allow this to be tested?You can build and boot a mipsel vmlinux by following the steps I described previously. In the kernel messages you'll see the jazzsonic driver attempt to probe the device. When it succeeds, you'll see the MAC address reported. You can also observe the regression I reported with regards to patch 2/6, "dp8393x: don't force 32-bit register access".Those instructions are useful, but since I am not a MIPS developer I don't have an existing toolchain/kernel tree and rootfs available to test this.You don't need a rootfs to see the jazzsonic driver messages. But if you still want one, you could try the mipsel builds from these distros (not the 64-bit ones): https://ftp.jaist.ac.jp/pub/Linux/Gentoo/experimental/mips/stages/ https://landley.net/aboriginal/downloads/binaries/
That's true, but then this wouldn't enable testing of Phil's proposed CRC changes. Having a simple shell with ping and wget/curl is a real help here.
If you can provide me with a link to your vmlinux and rootfs with busybox or similar in it, I can take a look to see what is happening here. Otherwise it's almost impossible for me to understand and debug the problem you are seeing on your setup.Uploading kernels is a hassle (for me) as it brings a trust question and requires a file hosting service. I really should use PGP and organise a web of trust but that's very difficult given my rural location.
Given that these are only running in a VM I'm not too worried about trust. I also have a VPS with scp access that I could temporarily grant you access via an SSH public key if that helps?
ATB, Mark.
