Hi List, at the moment I run a 2.6.16.11 on this core. Because of some trouble with the USB 2.0 EHCI controller (which is wired on the internal PCI bus) I am thinking about running a more recent kernel. It was easy to build linux-2.6.28.1 based on the db1550_defconfig using the mips_4KCle-gcc (gcc version 4.0.0 (DENX ELDK 4.1 4.0.0)) toolchain. But I see nothing on the serial console after starting the kernel. Some time ago (10 month I think) I was testing the head of the git mips kernel and the system was booting with some trouble on the pci bus but I was able so see someting on the serial console. A quick search on this list show me http://www.linux-mips.org/archives/linux-mips/2008-11/msg00099.html the last activity on the alchemy chip. I just want to ask who is working with the au1550 on a more recent kernel than 2.6.16.11. I'll start now with some early printk to solve booting problems and than we will see ..... Kind regards, FN
